Introduction

The NS6139M deserializer chip is compliant to Automotive Wired High-Speed Media Transmission (HSMT) standard. Pairing with a compatible HSMT serializer, the NS6139M is used for transmission of forward video and bidirectional audio and control data for automotive display applications. 

The NS6139M 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 fixed data rate up to 12.8Gbps in the forward direction and 100Mbps in the backward direction. The NS6139M supports 15m Coaxial cable or 8m Shielded Twisted Pair (STP) cable at 12.8Gbps. The NS6139M 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 NS6139M 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.
