Introduction

The NS6129 deserializer chip is compliant to Automotive Wired High-Speed Media Transmission (HSMT) standard. Pairing with a compatible HSMT serializer, the NS6129 is used for transmission of forward video and bidirectional audio and control data for automotive display applications. The NS6129 receives the HSMT input over a single or dual HSMT links and converts the input to OpenLDI formatted output. Each HSMT link operates at a fixed data rate up to 12.8Gbps in the forward direction and 100Mbps in the backward direction. The NS6129 supports 15 meters Coaxial cable or 8 meters Shielded Twisted Pair (STP) cable at 12.8Gbps. The NS6129 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 NS6129 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.
