Product details
Overview
DS90UB929TRGCTQ1 from Texas Instruments is an AEC-Q100 Grade 2 automotive HDMI-to-FPD-Link III bridge serializer supporting 720p60 and WXGA video at up to 96 MHz TMDS clock with 24-bit color depth. It accepts HDMI v1.4b or DP++ inputs, extracts up to 8-channel audio, and drives a single AC-coupled FPD-Link III differential output for connection to DS90UB926Q-Q1/DS90UB928Q-Q1 deserializers in infotainment displays.
For engineers reviewing the DS90UB929TRGCTQ1 datasheet, DS90UB929TRGCTQ1 pinout, DS90UB929TRGCTQ1 application, or DS90UB929TRGCTQ1 equivalent, key selection criteria include TMDS input compatibility (HDMI v1.4b/DP++), FPD-Link III serial output compliance, automotive temperature range (–40°C to +105°C), I²C master/slave control interface, and HDMI audio extraction capability.
Technical Context
The DS90UB929TRGCTQ1 implements a parallel-to-serial conversion architecture that maps HDMI's four TMDS differential pairs (clock + three data channels) onto a single FPD-Link III differential lane using scrambling and DC-balancing. Its receiver includes adaptive equalization and spread-spectrum clock monitoring to maintain lock under EMI stress and cable aging.
It supports dual-mode I²C operation (1.8 V or 3.3 V selectable via I2CSEL), bidirectional control channel (BCC) GPIOs for remote interrupt mirroring (REM_INTB) and local register access, and configurable power-down via PDB with <5 µA quiescent current. The device integrates dedicated 1.1-V analog supplies (VDDA11, VDDHA11, VDDP11) and separate 1.8-V I/O rails (VDDIO, VDD18).
