Product details
Overview
DS90UB949TRGCRQ1 from Texas Instruments is an AEC-Q100 Grade 2 automotive HDMI-to-FPD-Link III bridge serializer supporting 1080p60/24-bit video, TMDS clock up to 170 MHz, dual-lane FPD-Link III outputs, HDMI v1.4b input, and HDMI audio extraction for up to 8 channels - used in IVI head units and digital instrument clusters.
For engineers reviewing the DS90UB949TRGCRQ1 datasheet, DS90UB949TRGCRQ1 pinout, DS90UB949TRGCRQ1 application, or DS90UB949TRGCRQ1 equivalent, key selection considerations include HDMI-to-FPD-Link III bridging capability, dual-lane serial output support, automotive-grade thermal range (–40°C to +105°C), I²C/SPI control interface compatibility, and backward compatibility with DS90UB948-Q1 deserializers.
Technical Context
The DS90UB949TRGCRQ1 implements a full HDMI receiver front-end with TMDS clock/data recovery, HDCP-ready signaling path, and integrated HDMI audio extraction logic. It converts parallel HDMI video/audio into two high-speed FPD-Link III differential streams operating at up to 2.6 Gbps per lane.
Its dual-lane architecture supports forward-channel GPIO (up to 2 Mbps), bidirectional I²C and SPI pass-through over the same link, and automatic temperature/aging compensation for cable lengths up to 15 meters. The device uses separate 1.1-V analog/digital supplies and 1.8-V I/O supply to meet automotive noise immunity requirements.
