Introduction

The NS6139 deserializer chip is compliant to Automotive Wired High-Speed Media Transmission (HSMT) standard. Pairing with a compatible HSMT serializer, the NS6139 is used for transmission of forward video and bidirectional audio and control data for automotive display applications. The NS 6139 receives the HSMT input over a single or dual HSMT links and converts the input to DP/eDP formatted output. Each HSMT link operates at a fix ed data rate up to 12.8Gbps in the forward direction and 100Mbps in the backward direction. The NS6139 supports 15 meters Coaxial cable or 8 meters Shielded Twisted Pair (STP) cable at 12.8Gbps. The NS6139 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 NS6139 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.
