Introduction

     The NS6046 Serializer chip is compliant to Automotive Wired High-Speed Media Transmission (HSMT) standard. The NS6046 converts an 8-bit parallel data input to a single HSMT serial output for transmission of video and bi-directional control data. The HSMT link operates at a fixed data rate of 2.0Gbps in the forward direction, and 100Mbps in the backward direction. The NS6046 supports Power-over-Cable (PoC) operation over 22 meters Coaxial cable or 12 meters Shielded Twisted Pair (STP) cable, with multiple inline connectors. The NS6046 is ISO 26262 ASIL-B and AEC-Q100 Grade 2 certified with automotive temperature range of -40°C to +105°C.

     The NS6046 includes ISO 26262 ASIL-B certified 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.
