Product details
Overview
DS90UB929TRGCRQ1 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, and HDMI v1.4b input with audio extraction. It delivers single-lane FPD-Link III output over coaxial or STP cable for infotainment display links.
For engineers reviewing the DS90UB929TRGCRQ1 datasheet, DS90UB929TRGCRQ1 pinout, DS90UB929TRGCRQ1 application, or DS90UB929TRGCRQ1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade operating conditions (−40°C to +105°C), and cross-referenced compatibility with DS90UB926Q-Q1/DS90UB928Q-Q1 deserializers - all critical for IVI head unit and digital cluster design.
Technical Context
The DS90UB929TRGCRQ1 implements a full HDMI receiver front-end with TMDS clock/data recovery, HDCP-ready DDC interface, HPD monitoring, and CEC support, followed by parallel-to-serial conversion into FPD-Link III format. Its PLL locks to incoming TMDS clocks from 25 MHz to 96 MHz and supports spread-spectrum clock tracking to reduce EMI.
It integrates dual I2S interfaces - master-mode auxiliary audio (SWC/SCLK/SDIN/MCLK) and slave-mode local audio (I2S_WC/I2S_CLK/I2S_DA–DD) - enabling up to 8-channel HDMI audio extraction or external stereo input. The device uses dedicated 1.1-V analog supplies (VDDA11, VDDHA11, VDDHS11, VDDS11, VDDP11) and 1.8-V I/O supply (VDDIO) with configurable I2C voltage level (1.8 V or 3.3 V via I2CSEL).

Pinout & Package
DS90UB929TRGCRQ1 is housed in a 64-pin VQFN package (9.00 mm × 9.00 mm, 0.5-mm pitch) with exposed thermal pad requiring ≥9 vias to GND plane. Pin functions are validated per TI SNLS457B Rev B datasheet, including HDMI TMDS inputs (IN_CLK±, IN_D[2:0]±), FPD-Link III outputs (DOUT+/DOUT−), dual I2S interfaces, and multi-role GPIOs with register-controlled modes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN_CLK±, IN_D[2:0]± | HDMI TMDS differential inputs | Accept HDMI v1.4b video data/clock; require external 100-Ω differential termination and VTERM bias (1.8 V or 3.3 V) |
| DOUT+, DOUT− | FPD-Link III serial output | AC-coupled differential output driving coaxial or STP cable; 0.1-µF cap for 92x deserializers, 33-nF for 94x |
| SCL, SDA | I²C control bus | Open-drain bidirectional interface; pullup to VDDIO (1.8 V or 3.3 V); supports 1-MHz Fast-Mode Plus |
| PDB | Power-down mode control | LVCMOS input; logic low places device in low-power state (IDDZ11 = 15 mA typical) |
| HPD, RX_5V, DDC_SCL/SDA | HDMI hot-plug & DDC interface | HPD open-drain output (1-kΩ pullup to RX_5V); DDC lines pulled to RX_5V (47-kΩ); RX_5V detects HDMI source presence |
| I2S_WC/I2S_CLK/I2S_DA–DD | Slave-mode I2S audio input | Local stereo audio input path; shared pins with GPIO7_REG–GPIO3; requires external master clock and word clock |
| SWC/SCLK/SDIN/MCLK | Master-mode I2S auxiliary audio | Generates I2S signals for external DAC/codec; SCLK doubles as I2CSEL strap at power-up |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI-to-FPD-Link III bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90UB949TRGCRQ1 | Supports higher resolutions (1080p60, UXGA) and dual-lane FPD-Link III; includes embedded HDCP engine and enhanced audio features | Required for 1080p+ displays or systems needing HDCP compliance; consumes more power and requires additional layout care | Select DS90UB949TRGCRQ1 only when resolution or security requirements exceed DS90UB929TRGCRQ1 capabilities |
| DS90UB925TRGCRQ1 | Lower-cost variant with no HDMI input; accepts OpenLDI/RGB parallel input only; lacks DDC, HPD, and CEC interfaces | Suitable for non-HDMI sources (e.g., GPU RGB output); cannot replace DS90UB929TRGCRQ1 in HDMI-based systems | Choose DS90UB925TRGCRQ1 only for RGB-input display links where HDMI functionality is unnecessary |
Compared with DS90UB929TRGCRQ1, DS90UB949TRGCRQ1 adds resolution scalability and HDCP but increases cost and complexity, while DS90UB925TRGCRQ1 removes HDMI entirely - making DS90UB929TRGCRQ1 the optimal balance of HDMI integration, 720p performance, and automotive qualification for mainstream IVI displays.

FAQ
What video resolutions does the DS90UB929TRGCRQ1 support?
The DS90UB929TRGCRQ1 supports HDMI v1.4b input up to 720p60 and 1080i60 resolutions with 24-bit color depth, enabled by its TMDS clock recovery up to 96 MHz. It does not support 1080p60 or higher resolutions - those require DS90UB949TRGCRQ1. The device maintains pixel-accurate timing and jitter performance across its specified operating range.
Does DS90UB929TRGCRQ1 support HDCP?
The DS90UB929TRGCRQ1 does not include an embedded HDCP engine. It passes through HDCP authentication signaling via its DDC interface but relies on the upstream HDMI source for key management and encryption. For full HDCP 1.4 compliance with on-chip key handling, TI recommends DS90UB949TRGCRQ1 instead.
How is the I²C voltage level selected on DS90UB929TRGCRQ1?
The I²C voltage level for SCL and SDA on DS90UB929TRGCRQ1 is selected by the I2CSEL pin: tie to VDDIO with a 10-kΩ resistor for 1.8-V operation, or leave floating for 3.3-V operation. This configuration is sampled at power-up and determines the input thresholds and output drive strength of the open-drain I²C interface.
Can DS90UB929TRGCRQ1 drive both coaxial and shielded twisted-pair cables?
Yes - DS90UB929TRGCRQ1 supports both 50-Ω coaxial and 100-Ω shielded twisted-pair (STP) cabling via its AC-coupled FPD-Link III output. For coaxial or 92x-series deserializers, use 0.1-µF AC-coupling capacitors; for 94x-series deserializers, use 33-nF capacitors. Cable compensation operates automatically across both media types.
What power supplies are required for DS90UB929TRGCRQ1?
DS90UB929TRGCRQ1 requires seven distinct supply rails: VDD11 (1.1 V ±5% for analog/PLL cores), VDD18 (1.8 V ±5% for analog), VDDIO (1.8 V ±5% for I/O), VTERM (1.8 V or 3.3 V for HDMI termination), and three additional 1.1-V supplies (VDDHA11, VDDHS11, VDDS11) for TMDS, serializer, and digital domains - all specified in Section 6.3 of the datasheet.
