Product details
Overview
DS90UB924TRHSTQ1 from Texas Instruments is an AEC-Q100 Grade 2 automotive-qualified FPD-Link III deserializer that converts a single-pair AC-coupled high-speed serial stream (5–96 MHz pixel clock) into four LVDS data lanes, one LVDS clock pair (OpenLDI), and up to four I2S audio channels. It supports RGB888 + HS/VS/DE timing and 720p digital video output for in-vehicle displays.
For engineers reviewing the DS90UB924TRHSTQ1 datasheet, DS90UB924TRHSTQ1 pinout, DS90UB924TRHSTQ1 application, or DS90UB924TRHSTQ1 equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive-grade specifications, and real-world interface compatibility with DS90UB921-Q1 serializers and OpenLDI displays.
Technical Context
The DS90UB924TRHSTQ1 implements adaptive equalization on its FPD-Link III input (RIN±) to compensate for cable loss up to 100Q STP, enabling robust operation over long automotive harnesses. Its internal PLL locks to embedded clock data, generating precise TxCLKOUT± (5–96 MHz) and four synchronized TxOUT[3:0]± LVDS outputs compliant with OpenLDI timing standards.
It integrates bidirectional control via I²C (SCL/SDA), four configurable GPIOs (including shared I2S_DA/DB/DC/DD), and dedicated status pins (LOCK, PASS, INTB_IN). The device supports dual-voltage I/O (1.8 V or 3.3 V) and includes BIST, loop-through monitoring (CMLOUTP/N), and backward-compatible modes selected via MODE_SEL voltage divider.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pixel Clock Range | 5 MHz to 96 MHz - supports 720p video with precise timing alignment across all four LVDS data lanes and clock pair. |
| Input Interface | Single-pair FPD-Link III (AC-coupled RIN±) - enables EMI-reduced, skew-free transmission over 100Ω STP cable. |
| Output Interface | OpenLDI LVDS: TxCLKOUT± + TxOUT[3:0]± - provides standard-compliant RGB888 video output with external 100Ω differential termination. |
| I²C Control | Standard/Fast-mode (100/400 kHz) with open-drain SCL/SDA - allows host processor configuration and status readback without additional level-shifting. |
| Audio Interface | Up to 4 I2S outputs (MCLK, I2S_WC, I2S_CLK, I2S_DA–DD) - delivers stereo or surround sound directly to audio DACs or processors. |
| Supply & I/O | Single 3.3-V VDD33 supply; 1.8-V or 3.3-V LVCMOS I/O (VDDIO) - simplifies power design while supporting legacy and low-power logic interfaces. |
| AEC-Q100 Grade | Grade 2 (−40°C to +105°C ambient) - qualified for instrument cluster, navigation, and touch display applications in passenger compartments. |
Pinout & Package
DS90UB924TRHSTQ1 is housed in a thermally enhanced 48-pin WQFN package (7.0 mm × 7.0 mm), with exposed thermal pad (DAP) requiring ≥9 vias to ground plane. Pin functions are validated per TI SNLS512 datasheet Rev. APRIL 2016.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RIN+, RIN− | FPD-Link III differential input | AC-coupled receiver inputs with adaptive equalization; require 0.1-µF series capacitors per TI layout guidelines. |
| TxCLKOUT+, TxCLKOUT− | LVDS clock output | OpenLDI-compliant clock pair; requires external 100-Ω differential termination for proper signal integrity. |
| TxOUT[3:0]+, TxOUT[3:0]− | LVDS data outputs | Four true/inverting LVDS data lanes carrying RGB888 + DE/HS/VS; each pair needs 100-Ω termination. |
| SCL, SDA | I²C bidirectional control bus | Open-drain interface with mandatory 4.7-kΩ pullups to VDD33; supports register access and status monitoring. |
| LOCK, PASS | Status outputs | LVCMOS signals indicating PLL lock state (LOCK) and BIST pass/fail (PASS); routed to test points or MCU GPIOs. |
| PDB | Power-down mode input | Active-high enable pin; must be driven or pulled up to VDD33; asserts tri-state outputs and shuts down PLL when low. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive cable equalization | Compensates for deterministic jitter and insertion loss on 100Ω STP cables up to 15 m, ensuring reliable link at 96 MHz. |
| Bidirectional I²C control channel | Enables full register read/write over same FPD-Link III physical layer used for video/audio, eliminating separate control wiring. |
| Integrated BIST engine | Generates and verifies PRBS patterns internally; PASS output indicates error-free serial link integrity without external test equipment. |
| Configurable OpenLDI mapping | MAPSEL pin selects MSB-first or LSB-first data routing across TxOUT[3:0]±, matching serializer output order (e.g., DS90UB921-Q1). |
| Four-channel I2S audio support | Delivers independent stereo streams (I2S_DA–DD) with MCLK, word clock, and bit clock - suitable for multi-zone car audio systems. |
| Backward compatibility modes | MODE_SEL voltage divider configures BKWD, REPEAT, I2S_B, or LCBL modes - enables interoperability with legacy FPD-Link II systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPD-Link III deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90UB926TRHSTQ1 | Same 48-pin WQFN package; adds eDP-compatible output (not OpenLDI); supports higher 1080p resolution. | Targeted at premium displays requiring eDP sink capability; not drop-in compatible for OpenLDI-only systems. | Select DS90UB926TRHSTQ1 only if migrating to eDP-based display architecture and redesigning PCB layout. |
| DS90UB940TRGZTQ1 | 10-bit color depth (vs. 24-bit), no I2S audio outputs, different pinout (64-pin ZQZ), and no BIST engine. | Designed for cost-sensitive clusters with basic graphics; lacks audio integration and diagnostic features. | Choose DS90UB940TRGZTQ1 for non-audio, lower-resolution instrument panels where BIST and I2S are unnecessary. |
Compared with DS90UB924TRHSTQ1, DS90UB926TRHSTQ1 extends resolution and interface flexibility at the cost of OpenLDI compatibility, while DS90UB940TRGZTQ1 reduces feature set and package size for simpler, lower-cost implementations - neither offers pin-to-pin replacement.

FAQ
What is the maximum supported pixel clock frequency for DS90UB924TRHSTQ1?
The DS90UB924TRHSTQ1 supports pixel clock frequencies from 5 MHz to 96 MHz, enabling full 720p (1280×720 @ 60 Hz) video output with precise timing alignment. This range is specified under recommended operating conditions (TA = −40°C to +105°C, VDD33 = 3.3 V) and validated in TI SNLS512 datasheet Section 6.3.
Does DS90UB924TRHSTQ1 support I2S audio output, and how many channels are available?
Yes, DS90UB924TRHSTQ1 supports up to four I2S digital audio outputs (I2S_DA, I2S_DB, I2S_DC, I2S_DD) alongside MCLK, I2S_WC, and I2S_CLK - enabling stereo or multi-zone surround sound delivery. These outputs are LVCMOS and share pins with GPIO_REG[6:5] and GPIO[3:2], as defined in the pin function table (Section 5, SNLS512).
How does the adaptive equalization in DS90UB924TRHSTQ1 improve cable performance?
The DS90UB924TRHSTQ1 implements adaptive input equalization on its RIN± FPD-Link III receiver to compensate for high-frequency loss and deterministic jitter introduced by 100Ω STP cables. This enables reliable operation over extended lengths (up to 15 m) at 96 MHz without external equalizer ICs, reducing BOM cost and board space.
What is the role of the LOCK and PASS pins on DS90UB924TRHSTQ1?
LOCK is an LVCMOS output indicating PLL lock status (high = locked); PASS is an LVCMOS output signaling BIST result (high = error-free transmission). Both are used for system-level diagnostics: LOCK confirms stable video timing, while PASS validates serial link integrity - critical for functional safety monitoring in automotive displays.
Can DS90UB924TRHSTQ1 operate with both 1.8-V and 3.3-V LVCMOS I/O levels?
Yes, DS90UB924TRHSTQ1 supports dual-voltage LVCMOS I/O via the VDDIO pin, which accepts either 1.8 V (1.71–1.89 V) or 3.3 V (3.0–3.6 V) supplies. All GPIOs, I2S outputs, and control pins (SCL/SDA, MODE_SEL, etc.) auto-adapt to the selected VDDIO level, as detailed in Sections 6.5 and 6.6 of the SNLS512 datasheet.
