7. Function Description
7.1. Overview
The NSi822x is a Dual-channel digital isolator based on a capacitive isolation barrier technique. The digital signal is modulated with
RF carrier generated by the internal oscillator at the Transmitter side. Then it is transferred through the capacitive isolation barrier
and demodulated at the Receiver side.
The NSi822x devices are high reliability dual-channel digital isolator with AEC-Q100 qualified. The NSi822x device is safety certified
by UL1577 support several insulation withstand voltages (3.75kVrms, 5kVrms), while providing high electromagnetic immunity and low
emissions at low power consumption. The data rate of the NSi822x is up to 150Mbps, and the common-mode transient immunity
(CMTI) is up to 250kV/us. The NSi822x device provides digital channel direction configuration and the default output level
configuration when the input power is lost. Wide supply voltage of the NSi822x device support to connect with most digital interface
directly, easy to do the level shift. High system level EMC performance enhance reliability and stability of use.
The NSi822x has a default output status when VDDIN is unready and VDDOUT is ready as shown in Table 4.1, which helps for
diagnosis when power is missing at the transmitter side. The output B follows the same status with the input A within 60us after
powering up.

7.2. OOK Modulation
NSi822x is based on a capacitive isolation barrier technique and the digital signal is modulated with RF carrier generated by the
internal oscillator at the transmitter side, as shown in Figure 7.1, then it is transferred through the capacitive isolation barrier and
demodulated at the receiver side. The modulation uses OOK modulation technique with key benefits of high noise immunity and low
radiation EMI.

8. Application Note
8.1. Typical Application Circuit
Figure 8.1 Typical SCH for ISO CAN Interface
8.2. PCB Layout
The NSi822x requires a 0.1 µF bypass capacitor between VDD1 and GND1, VDD2 and GND2. The capacitor should be
placed as close as possible to the package. Figure 5.1 to Figure 5.4 show the recommended PCB layout, make sure the space under
the chip should keep free from planes, traces, pads and via. 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. The series resistors also improve the
system reliability such as latch-up immunity.
The typical output impedance of an isolator driver channel is approximately 50 Ω, ±40%. When driving loads where transmission line
effects will be a factor, output pins should be appropriately terminated with controlled impedance PCB traces.

with 350ps p-p jitter.
Figure8.5 NSi822x Eye Diagram
8.4. Typical Supply Current Equations
The typical supply current of NSi822x can be calculated using below equations. IDD1 and IDD2 are typical supply currents measured in
mA, f is data rate measured in Mbps, CL is the capacitive load measured in pF
NSi8220:
IDD1 = 0.19 *a1+1.45*b1+0.82*c1.
IDD2 = 1.36+ VDD1*f* CL *c1*10-9
When a1 is the channel number of low input at side 1, b1 is the channel number of high input at side 1, c1 is the channel number of
switch signal input at side 1.
NSi8221/ NSi8222:
IDD1 = 0.87 +1.26*b1+0.63*c1+ VDD1*f* CL *c2*10-9
IDD2 = 0.87 +1.26*b2+0.63*c2+ VDD1*f* CL *c1*10-9
When b1 is the channel number of high input at side 1, c1 is the channel number of switch signal input at side 1, b2 is the channel
number of high input at side 2, c2 is the channel number of switch signal input at side 2.
