19-2113; Rev 0; 8/01 16 x 16 Nonblocking Video Crosspoint Switch with On-Screen Display Insertion and I/O Buffers The MAX4356 is a 16 16 highly integrated video crosspoint switch matrix with input and output buffers and On-Screen Display (OSD) Insertion. This device operates from dual 3V to 5V supplies or from a single +5V supply. Digital logic is supplied from an independent single +2.7V to +5.5V supply. Individual outputs can be switched between an input video signal source and OSD information through an internal, dedicated fast 2:1 mux (40ns switching times) located before the output buffer. All inputs and outputs are buffered, with all outputs able to drive standard 75 reverse-terminated video loads. The switch matrix configuration and output buffer gain are programmed via an SPI/QSPITM-compatible, threewire serial interface and initialized with a single update signal. The unique serial interface operates in two modes facilitating both fast updates and initialization. On power-up, all outputs are initialized in the disabled state to avoid output conflicts in large-array configurations. Superior flexibility, high integration, and space-saving packaging make this nonblocking switch matrix ideal for routing video signals in security and video-ondemand systems. The MAX4356 is available in a 128-pin TQFP package and specified over an extended -40C to 85C temperature range.

All inputs and outputs are buffered, with all outputs able to drive standard 75 reverse-terminated video loads. A 3-wire interface programs the switch matrix and initializes with a single update signal. The unique serial interface operates in one of two modes: Complete Matrix Mode (Mode 1) or Individual Output Address Mode (Mode 0). In the Functional Diagram, the signal path of the MAX4356 is from the inputs (IN0-IN15), through the switching matrix, buffered by the output amplifiers, and presented at the output terminals (OUT0-OUT15). The other functional blocks are the serial interface and control logic. Each of the functional blocks is described in detail below. Analog Outputs The MAX4356 outputs are high-speed voltage feedback amplifiers capable of driving 150 (75 back-terminated) loads. The gain, A V = +1V/V or +2V/V, is selectable through programming bit 4 of the serial control word. Amplifier compensation is automatically opti- OSDKEY0 OSDKEY15 OSDKEY1 mized to maximize the bandwidth for each gain selection. Each output can be individually enabled and disabled through bit 5 of the serial control word. When disabled, the output is high impedance, presenting typically a 4k load, and 3pF output capacitance, allowing multiple outputs to be connected together in building large arrays. On power-up (or asynchronous RESET), all outputs are initialized in the disabled state to avoid output conflicts in large array configurations. The programming and operation of the MAX4356 is output referred. Outputs are configured individually to connect to any one of the 16 analog inputs, programmed to the desired gain (AV = +1V/V or +2V/V), or disabled in a high-impedance state. Analog Inputs The MAX4356 offers 16 analog input channels. Each input is buffered before the crosspoint switch matrix, allowing one input to cross-connect to up to 16 outputs. The input buffers are voltage feedback amplifiers with high input impedance and low-input bias current. This allows the use of very simple input clamp circuits. ______________________________________________________________________________________ 29 MAX4356 Functional Diagram MAX4356 16 x 16 Nonblocking Video Crosspoint Switch with On-Screen Display Insertion and I/O Buffers Table 1.

DOUT supplies original data in 96 SCLK pulses later. 1 Data in the serial 96-bit Complete Matrix Mode register is transferred into parallel latches that control the switching matrix. 1 Data at DIN is routed to the Individual Output Address Mode shift register. DIN is also connected directly to DOUT so that all devices on the serial bus may be addressed in parallel. 0 0 0 1 0 1 X Di X Di Di-96 X Di 1 1 0 1 1 1 OPERATION/COMMENTS 0 0 X Di Di 0 0 1 The 4-bit chip address A3 to A0 is compared to D13 to D10. If equal, the remaining 10 bits in the Individual Output Address Mode register are decoded, allowing reprogramming for a single output. AOUT signals a successful individual matrix update. X X X X X X X 0 Asynchronous reset. All outputs are disabled. Other logic remains unchanged. OSDFILL and OSDKEY Inputs Digital Interface Intended for on-screen display insertion, the 16 OSDFILL inputs are buffered analog signal inputs that are routed exclusively to a dedicated output buffer through a fast 2:1 Mux. The signal presented to the output buffer is selected from the programmed analog input signal (IN_) and the dedicated OSDFILL input signal. Each OSD Insertion Mux is controlled through the corresponding OSDKEY digital input to provide fast pixel switching. The digital interface consists of the following pins: DIN, DOUT, SCLK, AOUT, UPDATE, CE, A3-A0, MODE, and RESET. DIN is the serial data input; DOUT is the serial data output. SCLK is the serial data clock that clocks data into the Data Input registers (Figure 2). Data at DIN is loaded at each falling edge of SCLK. DOUT is the data shifted out of the 96-bit Complete Matrix Mode (Mode = 1). DIN passes directly to DOUT when in Individual Output Address Mode (Mode = 0). Switch Matrix The MAX4356 has 256 individual T-switches making a 16 x 16 switch matrix . The switching matrix is 100% nonblocking, which means that any input may be routed to any output. The switch matrix programming is output-referred. Each output may be connected to any one of the 16 analog inputs. Any one input can be routed to all 16 outputs with no signal degradation. 30 The falling edge of UPDATE latches the data and programs the matrix. When using individual output address mode, the address recognition output AOUT drives low when control word bits D13 to D10 match the address programming inputs (A3-A0) and UPDATE is low. Table 1 is the operation truth table. Programming the Matrix The MAX4356 offers two programming modes: individual output address mode and complete matrix mode. ______________________________________________________________________________________ 16 x 16 Nonblocking Video Crosspoint Switch with On-Screen Display Insertion and I/O Buffers BIT NAME 0 (LSB) Input Address 0 1 Input Address 1 2 Input Address 2 3 4 5 6 IC ADDRESS BIT A3 (MSB) A2 ADDRESS A1 A0 (LSB) CHIP ADDRESS (HEX) CHIP ADDRESS (DECIMAL) 0 0 0 0 0h 0 Input Address 3 0 0 0 1 1h 1 0 0 1 0 2h 2 0 0 1 1 3h 3 Gain Set Gain Select for output buffer, 0 = gain of +1V/V, 1 = gain of +2V/V 0 1 0 0 4h 4 0 1 0 1 5h 5 Output Enable Enable bit for output, 0 = disable, 1 = enable 0 1 1 0 6h 6 0 1 1 1 7h 7 LSB of output buffer address 1 0 0 0 8h 8 1 0 0 1 9h 9 1 0 1 0 Ah 10 Output Address B0 Output Address B1 8 Output Address B2 10 FUNCTION LSB of input channel select address MSB of input channel select address 7 9 Table 3.

Both modes operate with the same physical board layout. This flexibility allows initial programming of the IC by daisychaining and sending one long data word while still being able to address immediately and update individual outputs in the matrix. Individual Output Address Mode (MODE = 0) Drive MODE to logic low to select mode 0. Individual outputs are programmed through the serial interface with a single 16-bit control word. The control word consists of two don't care MSBs, the chip address bits, output address bits, an output enable/disable bit, an output gain-set bit, and input address bits (Tables 2 through 6, and Figure 2). In mode 0, data at DIN passes directly to DOUT through the data routing gate (Figure 3). In this configuration, the 16-bit control word is simultaneously sent to all chips in an array of up to 16 addresses. Complete Matrix Mode (MODE = 1) Drive MODE to logic high to select mode 1. A single 96-bit control word consisting of 16 six-bit control words programs all outputs. The 96-bit control word's first 6-bit control word (MSBs) programs output 15, and the last 6-bit control word (LSBs) programs output 0 (Table 7 and Figures 4 and 5). Data clocked into the 96-bit Complete Matrix Mode register is latched on the falling edge of UPDATE, and the outputs are immediately updated. Initialization String The Complete Matrix Mode (Mode = 1) is convenient to use to program the matrix at power-up.

Mode 1: Complete Matrix Mode Programming 34 ______________________________________________________________________________________ 16 x 16 Nonblocking Video Crosspoint Switch with On-Screen Display Insertion and I/O Buffers On-Screen-Display Fast Mux The MAX4356 features an asynchronous dedicated 2:1 Mux for each output buffer amplifier. Fast 40ns switching times enable pixel switching for on-screen-display (OSD) information such as text or other picture-in-picture signals (Figure 1). OSDFILL_ inputs are buffered analog inputs connected to each dedicated OSD Mux. Switching between the programmed IN_ input from the crosspoint switch matrix and the OSDFILL_ is accomplished by driving the dedicated OSDKEY_ digital input. A logic low on OSDKEYi routes the analog signal at OSDFILLi to the OUTi output buffer. OSDKEY_ control does not affect the crosspoint switch matrix programming or the output buffer enable/disable or gain-set programming. RESET The MAX4356 features an asynchronous bidirectional RESET with an internal 20k pullup resistor to V DD. When RESET is pulled low, either by internal circuitry, or driven externally, the analog output buffers are latched into a high-impedance state. After RESET is released, the output buffers remain disabled. The outputs may be enabled by sending a new 96-bit data word or a 16-bit individual output address word. A reset is initiated from any of three sources. RESET can be driven low by external circuitry to initiate a reset, or RESET can be pulled low by internal circuitry during power-up (power-on reset) or thermal shutdown. Since driving RESET low only clears the output buffer enable bit in the matrix control latches, RESET can be used to disable all outputs simultaneously. If no new data has been loaded into the 96-bit complete matrix mode register, a single UPDATE restores the previous matrix control settings. Power-On-Reset The power-on reset ensures all output buffers are in a disabled state when power is initially applied. A VDD voltage comparator generates the power-on-reset. When the voltage at VDD is less than 2.5V, the poweron-reset comparator pulls RESET low through internal circuitry. As the digital supply voltage ramps up crossing 2.5V, the MAX4356 holds RESET low for 40ns (typ). Connecting a small capacitor from RESET to DGND extends the power-on-reset delay. See Power-on Reset vs. RESET Capacitance in the Typical Operating Characteristics. Thermal Shutdown The MAX4356 features thermal shutdown protection with temperature hysteresis. When the die temperature exceeds +150C, the MAX4356 pulls RESET low, disabling the output buffers. When the die cools by 20C, the RESET pulldown is deasserted, and output buffers remain disabled until the device is programmed again. Applications Information Building Large Video Switching Systems The MAX4356 can be easily used to create larger switching matrices. The number of ICs required to implement the matrix is a function of the number of input channels, the number of outputs required, and whether the array needs to be nonblocking or not. The most straightforward technique for implementing nonblocking matrices is to arrange the building blocks in a grid. The inputs connect to each vertical bank of devices in parallel with the other banks. The outputs of each building block in a vertical column connect together in a wired-OR configuration. Figure 6 shows a 128-input, 32-output, nonblocking array using the MAX4356 16 x 16 crosspoint devices. The wired-OR connection of the outputs shown in the diagram is possible because the outputs of the IC devices can be placed in a disabled or high-impedance output state. This disable state of the output buffers is designed for a maximum impedance vs. frequency while maintaining a low output capacitance. These characteristics minimize the adverse loading effects from the disabled outputs. Larger arrays are constructed by extending this connection technique to more devices. Driving a Capacitive Load Figure 6 shows an implementation requiring many outputs to be wired together. This creates a situation where each output buffer sees not only the normal load impedance, but also the disabled impedance of all the other outputs. This impedance has a resistive and a capacitive component. The resistive components reduce the total effective load for the driving output. Total capacitance is the sum of the capacitance of all the disabled outputs and is a function of the size of the matrix. Also, as the size of the matrix increases, the length of the PC board traces increases, adding more capacitance. The output buffers have been designed to drive more than 30pF of capacitance while still maintaining a good AC response. Depending on the size of the array, the capacitance seen by the output can exceed this amount. There are several ways to improve the situation. The first is to use more building-block ______________________________________________________________________________________ 35 MAX4356 stream equal to n x 96 bits, where n is the number of MAX4356 devices on the bus. The first 96-bit data word programs the last MAX4356 in line (see Matrix Programming under Applications Information).

In Figure 7, the additional devices are placed in a second bank to multiplex the signals. This reduces the number of wired-OR connections. Another solution is to put a small resistor in series with the output before the capacitive load to limit excessive ringing and oscillations. Figure 8 shows the graph of the Optimal Isolation Resistor vs. Capacitive Load. A lowpass filter is created from the series resistor and parasitic capacitance to ground. A single R-C do not affect the performance at video frequencies, but in a very large system there may be many R-Cs cascaded in series. The cumulative effect is a slight rolling off of the high frequencies causing a "softening" of the picture. There are two solutions to achieve higher performance. One way is to design the PC board traces associated with the outputs such that they exhibit some inductance. By routing the traces in a repeating "S" configuration, the traces that are nearest each other will exhibit a mutual inductance increasing the total inductance. This series inductance causes the amplitude response to increase or peak at higher frequencies, offsetting the rolloff from the parasitic capacitance. Another solution is to add a smallvalue inductor to the output. On-Screen Display Insertion The MAX4356 facilitates the insertion of on-screen graphics and characters by using the built-in fast 2:1 multiplexer associated with each of the 16 outputs (Functional Diagram).

Access to this fast mux is through 16 dedicated OSDFILL analog inputs and 16 dedicated OSDKEY input controls. OSD timing is externally controlled and applied to the OSDKEY inputs (Figure 1). Pulling OSDKEYi low switches the signal on the OSDFILLi input to the OUTi output. When the OSDKEY signal is logic high, the signal at IN_ is switched to the output. This switching action is repeated on a pixel-by-pixel basis for each scan line. In this way any synchronized video signal, including arbitrary graphics, can be inserted on the screen (Figure 9). ______________________________________________________________________________________ 16 x 16 Nonblocking Video Crosspoint Switch with On-Screen Display Insertion and I/O Buffers COMPUTER CONTROL CAMERAS 30 ISOLATION RESISTANCE () MAX4356 OPTIMAL ISOLATION RESISTANCE vs. CAPACITIVE LOAD IN0 SYNC0 IN1 25 OUT0 MONITOR 0 SYNC1 20 IN15 15 OUT1 MAX4356 10 MONITOR 1 OSDFILL0 SYNC0 OSD SYNC15 OSDKEY0 5 OSDFILL1 SYNC1 OSD 0 0 100 200 300 400 500 CAPACITIVE LOAD (pF) SYNC15 OSD OSDKEY1 OUT15 MONITOR 15 OSDFILL15 OSDKEY15 Figure 8. Optimal Isolation Resistor vs. Capacitive Load MEMORY This technique for inserting OSD display information is an improvement over the way it has traditionally been done. Other OSD techniques require an external fast mux and a buffer for each output. Crosstalk Signal and Board Routing Issues Improper signal routing causes performance problems such as crosstalk. The MAX4356 has a typical crosstalk rejection of -62dB at 6MHz. A bad PC board layout degrades the crosstalk rejection by 20dB or more. To achieve the best crosstalk performance: 1) Place ground isolation between long critical signal PC board trace runs. These traces act as a shield to potential interfering signals. Crosstalk can be degraded by parallel traces as well as directly above and below on adjoining PC board layers. 2) Maintain controlled-impedance traces. Design as many of the PC board traces as possible to be 75 transmission lines. This lowers the impedance of the traces, reducing a potential source of crosstalk. More power will be dissipated due to the output buffer driving a lower impedance. 3) Minimize ground-current interaction by using a good ground plane strategy. In addition to crosstalk, another key issue of concern is isolation. Isolation is the rejection of undesirable feedthrough from input to output with the output disabled. The MAX4356 acheives a -110dB isolation at 6MHz by selecting the pinout configuration such that the inputs and outputs are on opposite sides of the package. Coupling through the power supply is a function of the quality and location of the supply bypassing. Use Figure 9. Improved Implementation of On-Screen Display appropriate low-impedance components and locate them as close as possible to the IC. Avoid routing the inputs near the outputs. Power-Supply Bypassing The MAX4356 operates from a single +5V or dual 3V to 5V supplies. For single-supply operation, connect all VEE pins to ground and bypass all power-supply pins with a 0.1F capacitor to ground. For dual-supply systems, bypass all supply pins to ground with 0.1F capacitors. Power in Large Systems The MAX4356 has been designed to operate with split supplies down to 3V or a single supply of +5V. Operating at the minimum supply voltages reduces the power dissipation by as much 40% to 50%. At 5V, the MAX4356 consumes 195mW (0.76mW/point). Driving a PC Board Interconnect or a Cable (AV = +1V/V or +2V/V) The MAX4356 output buffers can be programmed to either AV = +1V/V or +2V/V. The +1V/V configuration is typically used when driving a short-length (less than 3cm), high-impedance "local" PC board trace. To drive a cable or a 75 transmission line trace program the gain of the output buffer to +2V/V and place a 75 resistor in series with the output. The series termination resistor and the 75 load impedance act as a voltagedivider that divides the video signal in half. Set the gain to +2V/V to transmit a standard 1V video signal down a ______________________________________________________________________________________ 37 MAX4356 16 x 16 Nonblocking Video Crosspoint Switch with On-Screen Display Insertion and I/O Buffers cable. The series 75 resistor is called the back-match, reverse termination, or series termination. This 75 resistor reduces reflections, and provides isolation, increasing the output capacitive driving capability. Matrix Programming The MAX4356's unique digital interface simplifies programming multiple MAX4356 devices in an array. Multiple devices are connected with DOUT of the first device connecting to DIN of the second device, and so on (Figure 10). Two distinct programming modes, individual output address mode (MODE = 0) and complete matrix mode (MODE = 1), are selected by toggling a single MODE control pin high or low. Both modes operate with the same physical board layout. This allows initial programming of the IC by daisy-chaining and sending one long data word while still being able to address immediately and update individual locations in the matrix. Individual Output Address Mode (Mode 0) In Individual Output Address Mode, the devices are connected in a serial bus configuration, with the data routing gate (Figure 3) connecting DIN to DOUT, making each device a virtual node on the serial bus. A single 16-bit control word is sent to all devices simultaneously. Only the device with the corresponding chip address responds to the programming word, and updates its output. In this mode, the chip address is set through hardware pin strapping of A3-A0. The host then communicates with the device by sending a 16-bit word consisting of 2 don't care MSB bits, 4 chip address bits, and 10 bits of data to make the word exactly 2 bytes in length. The 10 data bits are broken down into 4 bits to select the output to be programmed; 1 bit to set the output enable, 1 bit to set gain, and 4 bits to select the input to be connected to that output. In this method, the matrix is programmed one output at a time. Complete Matrix Mode (Mode 1) In Complete Matrix Mode, the devices are connected in a daisy-chain fashion where n x 96 bits are sent to program the entire matrix, and where n = the number of MAX4356 devices connected in series. This long data word is structured such that the first bit is the LSB of the last device in the chain and the last data bit is the MSB of the first device in the chain. The total length of the data word is equal to the number of crosspoint devices to be programmed in series, times 96 bits per crosspoint device. This programming method is most often used at startup to initially configure the switching matrix. 38 +5V Single-Supply Operation with AV = +1V/V and +2V/V The MAX4356 guarantees operation with single +5V supply and gain of +1V/V for standard video input signals (1Vp-p). To implement a complete video matrix switching system capable of gain = +2V/V while operating with +5V single supply, combine the MAX4356 crosspoint switch with Maxim's low-cost, high-performance video amplifiers optimized for single +5V supply operation (Figure 11). The MAX4450 single and MAX4451 dual op amps are unity-gain-stable devices that combine high-speed performance with Rail-toRail(R) outputs. The common-mode input voltage range extends beyond the negative power-supply rail (ground in single-supply applications). The MAX4450 is available in the ultra-small 5-pin SC70 package, while the MAX4451 is available in a space-saving 8-pin SOT23. The MAX4383 is a quad op amp available in a 14-pin TSSOP package. The MAX4380/MAX4381/MAX4382 and MAX4384 offer individual output high-impedance disable making these amplifiers suitable for wired-OR connections.
