These products are based on Silicon Labs proprietary RF isolation technology and offer shorter propagation delays, lower power consumption, smaller installed size, and more stable operation with temperature and age versus opto couplers or other digital isolators. All devices in this family include hot-swap, bidirectional SDA and/or SCL isolation channels with open-drain, 35 mA sink capability that operate to a maximum frequency of 1.7 MHz. The 8-pin version (Si8600) supports bidirectional SDA and SCL isolation; the Si8602 supports bidirectional SDA and unidirectional SCL isolation, and the 16-pin versions (Si8605, Si8606) feature two unidirectional isolation channels to support additional system signals, such as interrupts or resets. All versions contain protection circuits to guard against data errors when an unpowered device is inserted into a powered system. Small size, low installed cost, low power consumption, and short propagation delays make the Si860x family the optimum solution for isolating I2C and SMBus serial ports.

The nominal output impedance of a non-I2C 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. 2. tPSK(P-P) is the magnitude of the difference in propagation delay times measured between different units operating at the same supply voltages, load, and ambient temperature.

VDE certifies storage temperature from -40 to 150 C. Rev. 1.2 13 Si860x 2. Functional Description 2.1. Theory of Operation The operation of an Si86xx 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 unidirectional Si86xx channel is shown in Figure 6. Transmitter Receiver RF OSCILLATOR A MODULATOR SemiconductorBased Isolation Barrier DEMODULATOR B Figure 6. 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 7 for more details. Input Signal Modulation Signal Output Signal Figure 7. Modulation Scheme 14 Rev. 1.2 Si860x 3. Typical Application Overview 3.1. I2C Background In many applications, I2C, SMBus, and PMBus interfaces require galvanic isolation for safety or ground loop elimination. For example, Power over Ethernet (PoE) applications typically use an I2C interface for communication between the PoE power sourcing device (PSE), and the earth ground referenced system controller. Galvanic isolation is required both by standard and also as a practical matter to prevent ground loops in Ethernet connected equipment. The physical interface consists of two wires: serial data (SDA) and serial clock (SCL). These wires are connected to open collector drivers that serve as both inputs and outputs. At first glance, it appears that SDA and SCL can be isolated simply by placing two unidirectional isolators in parallel, and in opposite directions. However, this technique creates feedback that latches the bus line low when a logic low asserted by either master or slave. This problem can be remedied by adding anti-latch circuits, but results in a larger and more expensive solution. The Si860x products offer a single-chip, anti-latch solution to the problem of isolating I2C/SMBus applications and require no external components except the I2C/SMBus pull-up resistors. In addition, they provide isolation to a maximum of 5.0 kVRMS, support I2C clock stretching, and operate to a maximum I2C bus speed of 1.7 Mbps. 3.2. I2C Isolator Operation Without anti-latch protection, bidirectional I2C isolators latch when an isolator output logic low propagates back through an adjacent isolator channel creating a stable latched low condition on both sides. Anti-latch protection is typically added to one side of the isolator to avoid this condition (the "A" side for the Si8600/02/05/06). The following examples illustrate typical circuit configurations using the Si8600/02/05/06. Si8600/02/05/06 I2C/SMBus Unit 1 + - VIL I2C/SMBus Unit 2 ISO1 V OL V IL V OL B Side A Side ISO2 Figure 8. Isolated Bus Overview (I2C Channels Only) The "A side" output low (VOL) and input low (VIL) levels are designed such that the isolator VOL is greater than the isolator VIL to prevent the latch condition. Rev. 1.2 15 Si860x 3.3. I2C Isolator Design Constraints Table 13 lists the I2C isolator design constraints. Table 13. Design Constraints Design Constraint To prevent the latch condition, the isolator output low level must be greater than the isolator input low level. The bus output low must be less than the isolator input low logic level. The isolator output low must be less than the bus input low. Data Sheet Values Effect of Bus Pull-up Strength and Temperature Isolator VOL 0.7 V typical Isolator VIL 0.5 V typical This is normally guaranteed by the isolator data sheet. However, if the pull up strength is too weak, the outInput/Output Logic Low Level put low voltage will fall and can get Difference too close to the input low logic level. VSDA1, VSCL1 = 50 mV minimum These track over temperature. Bus VOL = 0.4 V maximum Isolator VIL = 0.41 V minimum If the pull up strength is too large, the devices on the bus might not pull the voltage below the input low range. These have opposite temperature coefficients. Worst case is hot temperature. If the pull up strength is too large, the isolator might not pull below the Bus VIL 0.3 x VDD = 1.0 V minimum for bus input low voltage. VDD = 3.3 V Si8600/02/05/06 Vol: -1.8 mV/C CMOS buffer: -0.6 mV/C Isolator VOL = 0.8 V maximum This provides some temperature tracking, but worst case is cold temperature. 3.4. I2C Isolator Design Considerations The first step in applying an I2C isolator is to choose which side of the bus will be connected to the isolator A side. Ideally, it should be the side which: 1. Is compatible with the range of bus pull up specified by the manufacturer. For example, the Si8600/02/05/06 isolators are normally used with a pull up of 0.5 mA to 3 mA. 2. Has the highest input low level for devices on the bus. Some devices may specify an input low of 0.9 V and other devices might require an input low of 0.3 x Vdd. Assuming a 3.3 V minimum power supply, the side with an input low of 0.3 x Vdd is the better side because this side has an input low level of 1.0 V. 3. Have devices on the bus that can pull down below the isolator input low level. For example, the Si860x input level is 0.41 V. As most CMOS devices can pull to within 0.4 V of GND this is generally not an issue. 4. Has the lowest noise. Due to the special logic levels, noise margins can be as low as 50 mV. 16 Rev. 1.2 Si860x 3.5.

Device Operation Device behavior during start-up, normal operation, and shutdown is shown in Figure 15, where UVLO+ and UVLOare the positive-going and negative-going thresholds respectively. Refer to Table 14 to determine outputs when power supply (VDD) is not present. 4.1. 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. 4.2. Undervoltage Lockout Undervoltage 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 AVDD falls below AVDDUVLO- and exits UVLO when AVDD rises above AVDDUVLO+. Side B operates the same as Side A with respect to its BVDD supply.

Input and Output Characteristics for Non-I2C Digital Channels The unidirectional Si86xx inputs and outputs are standard CMOS drivers/receivers. 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. Table 14 details powered and unpowered operation of the Si86xx's non-I2C digital channels. Table 14. Si86xx 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 L6 H6,7 X5 P UP Comments Normal operation. Upon transition of VDDI from unpowered to powered, VO returns to the same state as VI in less than 1 s. Upon transition of VDDO from unpowered to powUndetermined ered, 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 3.0 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 26 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). For default high devices, the data channels have pull-ups on inputs/outputs. For default low devices, the data channels have pull-downs on inputs/outputs. 7. For I2C channels, the outputs for a given side go to Hi-Z when power is lost on the opposite side. 20 Rev. 1.2 Si860x 4.4. 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 9 and Table 7 on page 10 detail the working voltage and creepage/clearance capabilities of the Si86xx. 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. 4.4.1. Supply Bypass The Si860x family requires a 0.1 F bypass capacitor between AVDD and AGND and BVDD and BGND. The capacitor should be placed as close as possible to the package. To enhance the robustness of a design, the user may also include resistors (50-300 ) in series with the inputs and outputs if the system is excessively noisy. 4.4.2. Output Pin Termination The nominal output impedance of an non-I2C isolator 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. 4.5. Fail-Safe Operating Mode Si86xx 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 14 on page 20 and "6.Ordering Guide" on page 26 for more information. Rev. 1.2 21 Si860x 4.6.
