Introduction

The NS6162 serializer chip is compliant to Automotive Wired High-Speed Media Transmission (HSMT) standard. Pairing with a compatible HSMT deserializer, the NS6162 is used for transmission of forward video and bidirectional audio  and control data. The NS6162 converts a single or dual MIPI DSI inputs to HSMT output, and transmits the output to the paired deserializer over a single or dual HSMT links. Each HSMT link operates at a data rate up to 6.4Gbps in the forward direction and 100Mbps in the backward direction. The NS6162 supports 16 meters Coaxial cable or 10 meters STP cable at 6.4Gbps. The NS6162 is AEC-Q100 Grade 2 certified with automotive temperature range of -40°C to +105°C, and compliant  with ISO 10605 and IEC 61000-4-2 ESD standards.

The NS6162 is ISO 26262 ASIL-B certified and supports I2C and SPI control ports, flexible GPIO with trigger mode, constant latency mode and oversample mode, tunneled UART, forward and backward audio channels, a built-in ADC, temperature sensor, and an extensive set of diagnostics for functional safety.
