Page 11 GE Data Sheet PIM400 Series; ATCA Board Power Input Modules -36 to -75 Vdc; 400W/10A Feature Descriptions Output Pin Connections (Standard Module: PIM400Z) Introduction The PIM400X module is designed to support the Advanced Telecommunications Computing Architecture (ATCA) power entry distribution requirements for the Front Board / Blade per the PICMG 3.0 specifications. The PICMG 3.0 specification defines the Mechanical, Shelf Management Interface, Power Distribution, Thermal, Data I/O and Regulatory requirements for the next generation of modular telecom architecture platform for use in Central Office telecom environments. The output pin connections of the PIM400X to the system board are described below: From To PIM400X ATCA Front Board Pin Pin Terminal Component # Designation 15 -48V_OUT Vin(-) DC/DC Converter 17 VRTN_OUT Vin(+) DC/DC Converter 18 V_HLDP +ve Holdup Capacitor Input Pin Connections 16 TRIM_HLDP RTrim Holdup Capacitor The ATCA board is specified to accept up to a maximum of 400W of input power via dual, redundant -48Vdc Feeds through the Zone 1 (Power and Management) connector, designated P10. 8 +5V0 9 +3V3 14 ALARM The power connector provides board to backplane engagement via pins of varying lengths. Please consult the PICMG 3.0 specifications for details. The following are the design considerations of the input pin connections of the PIM400X to the ATCA power connector.

The last pins to engage are the two short pins, ENABLE_A & ENABLE_B. The ATCA backplane connects the ENABLE_A to VRTN_A, ENABLE_B to VRTN_B, EARLY_A to -48V_A and EARLY_B to -48V_B. EARLY_A & EARLY_B Connections: During hot insertion of the ATCA board, the Inrush Control circuit limits the surge current to the C_FLTR capacitor. However, due to the presence of a small amount of internal EMI filter capacitance (located before the Inrush Control circuit), it is recommended that Precharge resistors, R1 & R2 (100 Ohms, with appropriate surge capability) be connected as shown in the Typical Application circuit. June 10, 2015 (2) The following additional output pins of the PIM400KZ available for I2C Digital Interface to the IMP/System Controller are defined below: To Requirement (1) Additional Output Pin Connections (Modules with optional I2C Digital Interface: Option - K) PIM400X Connection Rpull-up Notes Notes (5) Inrush Current Control / Hot Plug Functionality The module provides inrush current control / hot plug capability. The peak value of the inrush current and the duration complies with the PICMG 3.0's Inrush Transient specifications. The specifications shall be met with the external C_HLDP and C_FLTR capacitances as specified in the previous sections. The unique design of the module where the large energy storage capacitors are segregated from the input filter capacitors allows the module to meet the stringent PICMG's inrush transient specifications with minimal energy storage capacitors. Design Considerations -48V Main Output Bus: (Signal Names: -48V_OUT & VRTN_OUT) This is the main -48V output bus that provides the payload power to the downstream (one or more) DC/DC converters. The (c)2015 General Electric Company. All rights reserved. Page 12 GE Data Sheet PIM400 Series; ATCA Board Power Input Modules -36 to -75 Vdc; 400W/10A PIM400X module does not regulate or provide isolation from the input -48V A/B feeds. The main functionality of the module is to provide -48V A/B Feeds OR'ing, inrush protection for hot swap capability and EMI filtering to attenuate the noise generated by the downstream DC/DC converters. The -48V_OUT pin connects to the Vin(-) pin and the VRTN_OUT pin connects to the Vin(+) pin of the DC/DC converter(s). The -48V_OUT bus may require a fuse depending on the power and fusing requirements of the DC/DC converter. Input filtering of the DC/DC converter is provided by C_FLTR close to the input pins of the DC/DC converter(s); additional high frequency decoupling ceramic capacitors (0.01 to 0.1F are recommended for improved EMI performance. The maximum C_FLTR capacitance across all the downstream DC/DC converters should not exceed 300F. The minimum C_FLTR capacitance (80F) recommendation is based on meeting the EMI requirements. Holdup Capacitor Output Voltage (V_HLDP) This output provides the user settable high voltage to charge the C_HLDP capacitor(s) to allow the ATCA board to meet the 5ms, 0Volts transient requirements. The V_HLDP pin connects to the +ve terminals of the C_HLDP capacitors while the -ve terminals of the C_HLDP connects to the -48V_OUT bus. The C_HLDP capacitance is dependent on the system power and the holdup time requirements based on the following formula Where THU is the desired holdup time, PHU is the holdup power drawn from the holdup capacitors (=input power of the downstream DC/DC bus converter + Management Power), V_HLDP is the trimmed holdup capacitor voltage and V UV is the undervoltage lockout threshold of either the downstream bus or the Management Power DC/DC converter (higher of the two). capacitance to less than -60Vdc and less than 20 joules within one second of disconnection from the backplane. Management Power (+3V3, +5V0) Two isolated secondary output voltages (+3V3 & +5V0) are provided for ATCA Front Board's IPM/System Controller (3.3V) and for the Blue LED's (5.0V) power requirements. Both the outputs are referenced to LOGIC_GND. The management power is available even when the input voltage is down to -36Vdc. No additional output capacitors are required, but a 22F tantalum/ceramic and a 0.01 to 0.1F ceramic capacitors are highly recommended to contain the switching ripple and noise. Input Fault Alarm Signal (ALARM) Both the input feeds, -48V_AF & -48_BF are monitored via the 48V_ALARM signal. In the event of a loss of power from either feeds (-48V_A or -48V_B) or the opening of their respective fuses, the -48V_ALARM shall change its logical state indicating a fault. During normal operation, the signal is Low. During fault condition, the alarm signal shall assume a HI state when the ALARM pin is pulled up to an external pull voltage (maximum 5.0V) via an external pullup resistor (RPullup). The ALARM output is internally referenced to the LOGIC_GND. A 3.3K pull up resistor to 3.3V Management Power should suffice. EMI Filtering The module incorporates an EMI filter that is designed for the ATCA board to help meet the conducted emissions requirements of CISPR 22 Class B when used in conjunction with GE's DC/DC bus converters recommended for ATCA applications. The following Figure 14 depicts the Class B EMI performance of PIM400F when tested with GE's bus converter, QBVW033A0B1 with both modules mounted on the PIM400 Evaluation Board together with additional high frequency EMI capacitors (Fig 15). Holdup Capacitor Trim Voltage (TRM_HLDP) The resistor R_TRIM sets the external holdup capacitor voltage to the desired setting. The output voltage is adjustable from 50 to 90V. The resistor, R_TRIM is selected by the following equation: High Voltage Discharge Mechanism: Per the PICMG 3.0 specifications, the PIM400 provides an internal discharge mechanism to discharge the holdup/bulk June 10, 2015 Figure 14.

Page 13 GE Data Sheet PIM400 Series; ATCA Board Power Input Modules -36 to -75 Vdc; 400W/10A AIRFLOW For Safety and noise considerations, copper traces must not be routed directly under the power module (PWB top layer). C_EMI capacitors must make direct connections (preferably without vias) to the bus converter (DC/DC) module pins with as much copper width as possible. In case vias are necessary, allow for multiple connections to the inner plane with vias placed outside the footprint of the module. For additional layout guide-lines, refer to GE's FLT012A0Z Input Filter Module data sheet. Safety Considerations For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e. UL* 60950-1, 2nd Ed. Recognized, CSA C22.2 No. 60950-1-07 Certified, and VDE (EN60950-1, 2nd Ed.) Licensed. The power input to these units is to be provided with a maximum of fast acting 20A fuses with a voltage rating of at least 75Vdc. Refer to "Thermal Consideration" section for additional safety considerations. Figure 16. Tref Temperature Measurement Location. Heat Transfer via Convection Increased airflow over the module enhances the heat transfer via convection. Derating curves showing the maximum output current that can be delivered by each module versus local ambient temperature (TA) for natural convection and up to 2 m/s (400 lfm) forced airflow are shown in Figures 17 & 18. Please refer to the Application Note "Thermal Characterization Process For Open-Frame Board-Mounted Power Modules" for a detailed discussion of thermal aspects including maximum device temperatures. - 48V OUTPUT CURRENT (A) Figure 15. PIM400 & QBVW033A0 Bus Converter Test setup schematic AMBIENT TEMEPERATURE, TA (oC) The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The thermal reference point, Tref, used in the specifications is shown in Figure 16. For reliable operation this temperature should not exceed 130oC.

Page 14 GE Data Sheet PIM400 Series; ATCA Board Power Input Modules -36 to -75 Vdc; 400W/10A Layout Considerations Storage and Handling The power modules are low profile in order to be used in fine pitch system card architectures. As such, component clearance between the bottom of the power module and the mounting board is limited. Avoid placing copper areas on the outer layer directly underneath the power module. Also avoid placing via interconnects underneath the power module. Particular attention should be paid to the clearance area as noted in the Bottom View of the Mechanical Outline drawing. The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of 30C and 60% relative humidity varies according to the MSL rating (see J-STD-033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40 C, < 90% relative humidity. For additional layout guidelines, refer to FLT012A0Z Data Sheet. Process Considerations Through-Hole Lead-Free Soldering Information Peak Temp. 240-245C Temp The RoHS-compliant, Z version, through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. The module is designed to be processed through single or dual wave soldering machines. The pins have a RoHScompliant, pure tin finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Ramp down max. 4C/Sec 217C 200C Time Limited 90 Sec. above 217C 150C Preheat time 100-150 Sec.

Max. sustain temperature : 245C (J-STD-020C Table 4-2: Packaging Thickness>=2.5mm / Volume > 2000mm3), Peak temperature over 245C is not suggested due to the potential reliability risk of components under continuous hightemperature.

Time Figure 19. Recommended linear reflow profile using Sn/Ag/Cu solder. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to GE Board Mounted Power Modules: Soldering and Cleaning Application Note (AP01-056EPS). For additional information, please contact your Sales representative for more details. Pb-free Reflow Profile BMP module will comply with J-STD-020 Rev. C (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pbfree solder profiles and MSL classification procedures. BMP will comply with JEDEC J-STD-020C specification for 3 times reflow requirement. The suggested Pbfree solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Figure 19. MSL Rating The modules have a MSL rating of 2a. June 10, 2015 (c)2015 General Electric Company. All rights reserved.

Four bits are fixed (0101), three bits (xyz) are variable, and the least-significant bit is the read/write bit. 8 bit Address 0101 xyz* R/W Table 3: Address structure Modules with I2C Option Features: Address Selection: The three bits (xyz) of the address are set with a single external resistor from the ADD (pin10) to LOGIC_GND (pin 13). The 8 possible addresses are shown in Table 4 with the respective resistance values. Table 1: Internal register memory map Table 2: Digital signals Table 4: I2C Addressing Note: Bit 0=LSB, Bit 7=MSB I2C Command Structure: The I2C is a 2-wire interface supporting multiple devices and masters on a single bus. The connected devices can only pull the bus wires low and they never drive the bus high. The bus wires should be externally connected to a positive supply voltage via a pull-up resistor. When the bus is idle, both DAT and CLK are high. The max sink current supported on the I2C bus is 3.5mA. Each device on the I2C bus is recognized by a unique address stored in that device. Devices can be classified as masters or slaves when performing data transfers. A master is a device which initiates a data transfer on the bus and generates clock signals to permit that transfer. At the same time, any device addressed is considered slave. The PIM400 always acts as a slave. In PIM400 module, I2C interface is used for reporting critical parameters like input voltage, output current, holdup capacitor voltage and temperature data.
