Low Power Six-Channel Digital Isolator

Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering sub-

stantial data rate, propagation delay, power, size, reliability, and external BOM advan-

tages over 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 propagation delays of

less than 10 ns. Ordering options include a choice of isolation ratings (1.0, 2.5, 3.75 and

5 kV) and a selectable fail-safe operating mode to control the default output state during

power loss. All products >1 kVRMS are safety certified by UL, CSA, VDE, and CQC, and

products in wide-body packages support reinforced insulation withstanding up to 5

kVRMS.

Automotive Grade is available for certain part numbers. These products are built using

automotive-specific flows at all steps in the manufacturing process to ensure the robust-

ness and low defectivity required for automotive applications.

2. Functional Description

2.1 Theory of Operation

The operation of an Si866x 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 Si866x channel is shown in the figure below.

OSCILLATOR

MODULATOR DEMODULATOR

A B

Semiconductor-

Based Isolation

Barrier

Transmitter Receiver

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 better immunity to

magnetic fields. See the figure below for more details.

2.2 Eye Diagram

The figure below illustrates an eye-diagram taken on an Si8660. 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 Si8660 were captured on an oscilloscope. The re-

sults 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 9, where UVLO+ and UVLO- are the positive-going and negative-going thresholds respectively. Refer to the table below to

determine outputs when power supply (VDD) is not present.

Table 3.1. Si866x Logic Operation

VI Input 1,2 VDDI State1,3,4 VDDO State1,3,4 VO Output1,2 Comments

H P P H Normal operation.

L P P L

X 5UP P L6

Upon transition of VDDI from unpowered to pow-

ered, VO returns to the same state as VI in less

than 1 µs.

X5P UP Undetermined Upon transition of VDDO from unpowered to pow-

ered, VO returns to the same state as VI within 1

µs.

Notes:

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 1. 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 devi-

ces, the data channels have pull-ups on inputs/outputs. For default low devices, the data channels have pull-downs on inputs/

outputs.

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.

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 <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 4.5 Regulatory Information 1 on

page 23 and Table 4.6 Insulation and Safety-Related Specifications on page 23 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.

3.3.1 Supply Bypass

The Si866x family requires a 0.1 µF 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, the user may also include resistors (50–300 Ω ) in series

with the inputs and outputs if the system is excessively noisy.

3.3.2 Output Pin Termination

The nominal output impedance of an isolator driver channel is approximately 50 Ω, ±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

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 3.1 Si866x Logic Operation on page 8 and

1. Ordering Guide for more information.

1. The nominal output impedance of an isolator driver channel is approximately 50 Ω, ±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.

3. Start-up time is the time period from the application of power to valid data at the output.

2. To determine resistance and capacitance, the Si86xx is converted into a 2-terminal device. Pins 1–8 are shorted together to form

the first termina and pins 9–16 are shorted together to form the second terminal. The parameters are then measured between

these two terminals.
