Introduction

The NS6232 serializer chip is compliant to Automotive Wired High-Speed Media Transmission (HSMT) standard.  Pairing with a compatible HSMT deserializer, the NS6232 converts DisplayPort/eDP input to dual HSMT outputs for transmission of forward video and bidirectional audio and control data. Each HSMT link operates at a data rate up to 6.4Gbps in the forward direction and 100Mbps in the backward direction. The NS6232 supports 16 meters Coaxial cable or 10 meters STP cable at 6.4Gbps. The NS6232 is AEC-Q100 Grade 2 certified with automotive temperature range of -40°C to +105°C, and meets ISO 10605 and IEC 61000-4-2 ESD requirements.

The NS6232 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.
