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. 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 7.1, 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. Table 7.1 Output status vs. power status Input VDD1 status VDD2 status Output H1 Ready Ready H L2 Ready Ready L X3 Unready Ready L(NSi822xx0) H(NSi822xx1 ) X Ready Unready X Comment Normal operation. The output follows the same status with the input within 60us after input side VDD1 is powered on. The output follows the same status with the input within 60us after output side VDD2 is powered on. Note: H=Logic high; L=Logic low; X=Logic low or logic high VDD1 is input side power; VDD2 is out side power. Copyright © 2022, NOVOSENSE Page 24 NSi8220/NSi8221/NSi8222 Datasheet (EN) 1.6 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.

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 8.2 to Figure 8.5 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.
