Introduction

The NS6129S deserializer chip is compliant to Automotive Wired High-Speed Media Transmission (HSMT) standard. Pairing with a compatible HSMT serializer. the NS6129S is used for transmission of forward video and bidirectional audio and control data for automotive display applications. 

The NS6129S 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 NS6129S supports 15m Coaxial cable or 8m Shielded Twisted Pair (STP) cable . The NS6129S 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.
