Description Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering substantial data rate, propagation delay, power, size, reliability, and external BOM advantages when compared to legacy isolation technologies. The operating parameters of these products remain stable across wide temperature ranges and throughout device service life for ease of design and highly uniform performance. All device versions have Schmitt trigger inputs for high noise immunity and only require VDD bypass capacitors. Data rates up to 150 Mbps are supported, and all devices achieve worst-case propagation delays of less than 10 ns. Ordering options include a choice of isolation ratings (up to 5 kV) and a selectable fail-safe operating mode to control the default output state during power loss. All products are safety certified by UL, CSA, and VDE, and products in wide-body packages support reinforced insulation withstanding up to 5 kVRMS.

Functional Description 2.1. Theory of Operation The operation of an Si84xx channel is analogous to that of an opto coupler, except an RF carrier is modulated instead of light. This simple architecture provides a robust isolated data path and requires no special considerations or initialization at start-up. A simplified block diagram for a single Si84xx channel is shown in Figure 4. Transmitter Receiver RF OSCILLATOR A MODULATOR SemiconductorBased Isolation Barrier DEMODULATOR B Figure 4. Simplified Channel Diagram A channel consists of an RF Transmitter and RF Receiver separated by a semiconductor-based isolation barrier. Referring to the Transmitter, input A modulates the carrier provided by an RF oscillator using on/off keying. The Receiver contains a demodulator that decodes the input state according to its RF energy content and applies the result to output B via the output driver. This RF on/off keying scheme is superior to pulse code schemes as it provides best-in-class noise immunity, low power consumption, and better immunity to magnetic fields. See Figure 5 for more details. Input Signal Modulation Signal Output Signal Figure 5. Modulation Scheme 20 Rev. 1.2 Si8410/20/21 (5 kV) Si8422/23 (2.5 & 5 kV) 2.2. Eye Diagram Figure 6 illustrates an eye-diagram taken on an Si8422. For the data source, the test used an Anritsu (MP1763C) Pulse Pattern Generator set to 1000 ns/div. The output of the generator's clock and data from an Si8422 were captured on an oscilloscope. The results illustrate that data integrity was maintained even at the high data rate of 150 Mbps. The results also show that 2 ns pulse width distortion and 250 ps peak jitter were exhibited. Figure 6. Eye Diagram Rev. 1.2 21 Si8410/20/21 (5 kV) Si8 422/23 ( 2. 5 & 5 k V) 3. Device Operation Device behavior during start-up, normal operation, and shutdown is shown in Figure 7, where UVLO+ and UVLOare the positive-going and negative-going thresholds respectively. Refer to Table 12 to determine outputs when power supply (VDD) is not present. Table 12. Si84xx Logic Operation Table VI Input1,4 VDDI State1,2,3 VDDO State1,2,3 VO Output1,4 H P P H L P P L X5 UP P Comments Normal operation. H6 (Si8422/23) Upon transition of VDDI from unpowered to (Si8410/20/21) powered, VO returns to the same state as VI in less than 1 s. L6 X5 P UP Undetermined Upon transition of VDDO from unpowered to powered, VO returns to the same state as VI within 1 s. Notes: 1. VDDI and VDDO are the input and output power supplies. VI and VO are the respective input and output terminals. 2. Powered (P) state is defined as 2.70 V < VDD < 5.5 V. 3. Unpowered (UP) state is defined as VDD = 0 V. 4. X = not applicable; H = Logic High; L = Logic Low. 5. Note that an I/O can power the die for a given side through an internal diode if its source has adequate current. 6. See "6. Ordering Guide" on page 29 for details. This is the selectable fail-safe operating mode (ordering option). Some devices have default output state = H, and some have default output state = L, depending on the ordering part number (OPN). 22 Rev. 1.2 Si8410/20/21 (5 kV) Si8422/23 (2.5 & 5 kV) 3.1. Device Startup Outputs are held low during powerup until VDD is above the UVLO threshold for time period tSTART. Following this, the outputs follow the states of inputs. 3.2. Under Voltage Lockout Under Voltage Lockout (UVLO) is provided to prevent erroneous operation during device startup and shutdown or when VDD is below its specified operating circuits range. Both Side A and Side B each have their own undervoltage lockout monitors. Each side can enter or exit UVLO independently. For example, Side A unconditionally enters UVLO when VDD1 falls below VDD1(UVLO-) and exits UVLO when VDD1 rises above VDD1(UVLO+). Side B operates the same as Side A with respect to its VDD2 supply.

Layout Recommendations To ensure safety in the end user application, high voltage circuits (i.e., circuits with >30 VAC) must be physically separated from the safety extra-low voltage circuits (SELV is a circuit with <30 VAC) by a certain distance (creepage/clearance). If a component, such as a digital isolator, straddles this isolation barrier, it must meet those creepage/clearance requirements and also provide a sufficiently large high-voltage breakdown protection rating (commonly referred to as working voltage protection). Table 6 on page 16 and Table 7 on page 17 detail the working voltage and creepage/clearance capabilities of the Si84xx. These tables also detail the component standards (UL1577, IEC60747, CSA 5A), which are readily accepted by certification bodies to provide proof for end-system specifications requirements. Refer to the end-system specification (61010-1, 60950-1, 60601-1, etc.) requirements before starting any design that uses a digital isolator. 3.3.1. Supply Bypass The Si841x/2x family requires a 0.1 F bypass capacitor between VDD1 and GND1 and VDD2 and GND2. The capacitor should be placed as close as possible to the package. To enhance the robustness of a design, it is further recommended that the user also add 1 F bypass capacitors and include 100 resistors in series with the inputs and outputs if the system is excessively noisy. 3.3.2. Pin Connections No connect pins are not internally connected. They can be left floating, tied to VDD, or tied to GND. 3.3.3. Output Pin Termination The nominal output impedance of an isolator driver channel is approximately 50 , 40%, which is a combination of the value of the on-chip series termination resistor and channel resistance of the output driver FET. When driving loads where transmission line effects will be a factor, output pins should be appropriately terminated with controlled impedance PCB traces. 3.4. Fail-Safe Operating Mode Si84xx devices feature a selectable (by ordering option) mode whereby the default output state (when the input supply is unpowered) can either be a logic high or logic low when the output supply is powered. See Table 12 on page 22 and "6. Ordering Guide" on page 29 for more information. 24 Rev. 1.2 Si8410/20/21 (5 kV) Si8422/23 (2.5 & 5 kV) 3.5.
