Product details
Overview
DS90UH929TRGCRQ1 from Texas Instruments is an AEC-Q100 Grade 2 automotive HDMI-to-FPD-Link III bridge serializer supporting 720p60/1080i60 video at up to 96 MHz TMDS clock, 24-bit color depth, integrated HDCP v1.4 cipher engine, and HDMI audio extraction for up to 8 channels. It operates across –40°C to +105°C and interfaces with DS90UH926Q-Q1/DS90UH928Q-Q1 deserializers in infotainment head units.
For engineers reviewing the DS90UH929TRGCRQ1 datasheet, DS90UH929TRGCRQ1 pinout, DS90UH929TRGCRQ1 application, or DS90UH929TRGCRQ1 equivalent, key selection considerations include TMDS input compatibility (HDMI v1.4b/DP++), FPD-Link III single-lane AC-coupled differential output, HDCP repeater functionality, I²C master/slave control at 1 Mbps, and 64-pin VQFN package thermal performance (RθJA = 25.8°C/W).
Technical Context
The DS90UH929TRGCRQ1 implements a parallel-to-serial conversion architecture that accepts HDMI v1.4b/DP++ TMDS inputs (IN_CLK±, IN_D[2:0]±) and outputs a single-lane FPD-Link III stream (DOUT+/DOUT−) with embedded bidirectional control channel (BCC) for I²C and GPIO communication. It integrates a full HDCP v1.4 repeater engine with on-chip key storage, enabling authentication and re-encryption without external controller involvement.
Its timing architecture includes dual PLLs calibrated at power-up for stable lock across temperature ramps (TCLH1 = 80°C, TCLH2 = 105°C), supports spread-spectrum clock monitoring to reduce EMI, and provides configurable I²S audio interface (master/slave modes) with MCLK, I2S_WC, I2S_CLK, and four data lanes (I2S_DA–I2S_DD). Power domains are segregated into VDD11 (1.1 V), VDD18 (1.8 V), VDDIO (1.8 V), and VTERM (1.8 V or 3.3 V), each with defined operating tolerances.

FAQ
What video resolutions does the DS90UH929TRGCRQ1 support?
The DS90UH929TRGCRQ1 supports HDMI v1.4b input up to 720p60 and 1080i60 resolutions with 24-bit color depth, enabled by its 96 MHz TMDS clock capability. It does not support 1080p60 or 4K formats. The device is optimized for automotive-grade video links where latency, EMI robustness, and HDCP compliance are prioritized over ultra-high resolution.
Does the DS90UH929TRGCRQ1 require an external HDCP controller?
No, the DS90UH929TRGCRQ1 includes a fully integrated HDCP v1.4 cipher engine with on-chip key storage, enabling standalone repeater functionality. This eliminates the need for an external controller in applications such as rear seat entertainment systems, reducing system complexity and bill-of-materials cost while maintaining content protection compliance.
Which deserializers are compatible with the DS90UH929TRGCRQ1?
The DS90UH929TRGCRQ1 is explicitly compatible with DS90UH926Q-Q1 and DS90UH928Q-Q1 FPD-Link III deserializers, as confirmed in TI's official documentation. It also supports interoperability with DS90UH940-Q1 and DS90UH948-Q1 deserializers, though AC coupling capacitor values differ (0.1 µF for 92x, 33 nF for 94x devices).
What power supply voltages does the DS90UH929TRGCRQ1 require?
The DS90UH929TRGCRQ1 requires five distinct supply rails: VDD11 (1.1 V ±5%), VDD18 (1.8 V ±5%), VDDIO (1.8 V ±5%), VTERM (1.8 V or 3.3 V ±5% depending on AC/DC coupling), and multiple domain-specific 1.1-V supplies (VDDA11, VDDHA11, VDDHS11, VDDL11, VDDP11, VDDS11). Each rail has defined current requirements and thermal derating limits per the datasheet.
How is thermal management implemented for the DS90UH929TRGCRQ1 in automotive applications?
The DS90UH929TRGCRQ1 uses a 64-pin VQFN package with an exposed thermal pad requiring connection to the PCB ground plane via ≥9 vias. Its RθJA is 25.8°C/W, and junction temperature must remain ≤150°C. TI specifies thermal design guidelines including copper pour area, layer stack-up, and airflow assumptions to maintain operation within –40°C to +105°C ambient conditions during sustained 330 mA IDD11 load.
