Si861x/2x Data Sheet
System Overview
2. System Overview
2.1 Theory of Operation
The operation of an Si861x/2x 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 Si861x/2x channel is shown in the figure below.
Figure 2.1. 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 improved immunity
to magnetic fields. See the following figure for more details.

System Overview
2.2 Eye Diagram
The figure below illustrates an eye diagram taken on an Si8610. 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 Si8610 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 350 ps peak jitter were exhibited.

3. Device Operation
Device behavior during start-up, normal operation, and shutdown is shown in Figure 3.1 Device Behavior during Normal Operation on
page 8, where UVLO+ and UVLO– are the respective positive-going and negative-going thresholds. Refer to the following table to
determine outputs when power supply (VDD) is not present.

Normal operation.
Upon transition of VDDI from unpowered to powered, VO returns to the same state as VI in less than 1 µs.
Upon transition of VDDO from unpowered to powered, VO returns to the same state as VI within 1 µs.
Note:
1. VDDI and VDDO are the input and output power supplies. VI and VO are the respective input and output terminals.
2. X = not applicable; H = Logic High; L = Logic Low; Hi-Z = High Impedance.
3. “Powered” state (P) is defined as 2.5 V < VDD < 5.5 V.
4. “Unpowered” state (UP) is defined as VDD = 0 V.
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 Ordering Guide 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.

Device Operation
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 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 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.
Figure 3.1. Device Behavior during Normal Operation
3.3 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 109
