DS90UH949TRGCTQ1 Overview
Key specifications include a 5.95 Gbps forward-channel data rate (up to 2.975 Gbps per lane), integrated HDCP 1.4 cipher engine for content-protected video transport, an embedded clock over the bidirectional control channel, and an I2C-compatible pass-through interface for remote peripheral access. The device accepts up to three digital-input video sources and provides an adaptive equalization receiver on the back-channel, enabling operation across long-distance STP or coaxial cables commonly used in automotive infotainment backbones.
A serializer/deserializer pair, often abbreviated SerDes, is a fundamental building block of modern in-vehicle video distribution. SerDes converters sit in the signal chain between a graphics source (HDMI, DSI, OpenLDI) and a remote display panel, compressing parallel RGB/clock lines into a high-speed serial stream and embedding the clock in the data - which dramatically reduces wiring harness count, EMI, and connector pin count. FPD-Link III is TI's third-generation Flat Panel Display Link family, designed for AEC-Q100-qualified automotive display modules; it adds HDCP content protection, bidirectional I2C/audio transport, and adaptive equalization on top of the original FPD-Link II architecture.
A differential output architecture and integrated PLL with low jitter reduce the need for external clock-recovery components. Automotive-grade qualification (AEC-Q100) makes the DS90UH949TRGCTQ1 a drop-in solution for head-unit-to-display video transport in instrument clusters, center-stack displays, and rear-seat entertainment. Compatibility with backward-mode 24-bit color and reduced blanking formats lets the same part serve legacy panels.
Typical applications include automotive head-unit video links, digital instrument clusters, HUD projectors, and rear-seat entertainment displays. The DS90UH949TRGCTQ1 also serves industrial touch-panel bridges and medical imaging displays where HDCP-protected video must traverse long cables. The device pairs naturally with the DS90UH940-Q1 deserializer for full HDCP-end-to-end support.
When designing with this part, follow TI's reference layout for the 64-VQFN exposed pad, which provides the primary thermal path; insufficient solder coverage will derate the thermal envelope. Use AC-coupled interconnects on the FPD-Link III output, keep the HDMI input traces impedance-controlled at 100 ohms differential, and place the local 1.8 V/3.3 V decoupling within 5 mm of each supply pin.

Typical Applications
DS90UH949TRGCTQ1 is suitable for 7 applications: Automotive Head Unit to Display Video Link, Digital Instrument Cluster Serializer, Rear-Seat Entertainment (RSE) Display Module, Heads-Up Display (HUD) Optical Engine, Industrial Touch Panel and HMI Bridge, Medical Imaging Display Bridge, Surveillance and Security Video Walls.
Automotive Head Unit to Display Video Link
The DS90UH949TRGCTQ1 is purpose-built for automotive head-unit-to-display video distribution, where it serializes the HDMI output of an infotainment SoC onto a single differential pair running across the vehicle harness. Its 5.95 Gbps forward channel and integrated HDCP 1.4 cipher engine support 1080p60 protected content end-to-end, while AEC-Q100 Grade 2 qualification (-40 C to +105 C) ensures reliable operation in cabin thermal environments. The bidirectional I2C pass-through allows the head unit to read panel EDID and control backlight/TCON registers at the remote display side, replacing dozens of LVDS/RGB lines with one STP cable, which cuts harness weight, EMI, and connector pin count.
Recommended
Digital Instrument Cluster Serializer
For digital instrument clusters that must drive a remote TFT-LCD panel behind the steering wheel, the DS90UH949TRGCTQ1's HDMI input accepts direct RGB888 from cluster graphics processors with full HDCP support. Its low-latency serializer path (single-digit line latencies) preserves the real-time responsiveness critical for gauge animations and turn-by-turn navigation prompts. The AEC-Q100 Grade 2 rating and -40 C to +105 C operating range suit under-dash thermal envelopes, and the bidirectional back-channel carries touch/button events back to the cluster MCU without a second wiring harness. Reference designs in TI's automotive display portfolio pair this part with the DS90UH940-Q1 deserializer at the panel end.
Recommended
Rear-Seat Entertainment (RSE) Display Module
In rear-seat entertainment systems, the DS90UH949TRGCTQ1 transports HDCP-protected Blu-ray or streaming HDMI content from a central head unit to one or two ceiling-mounted displays. The 5.95 Gbps forward-channel bandwidth accommodates 1080p60 with multi-channel audio over a single twisted pair, simplifying routing through seat frames and headliners. The integrated I2S and S/PDIF audio channels deliver multi-channel sound to remote speakers without additional wiring, and the bidirectional control channel lets passengers control playback via remote IR or capacitive buttons at the display side.
Recommended
Heads-Up Display (HUD) Optical Engine
HUD optical engines require compact, EMI-isolated serializer paths from the instrument-cluster graphics processor to a remote projection module. The DS90UH949TRGCTQ1 replaces parallel RGB/clock lines with a single differential pair, eliminating radiated emissions that would otherwise interfere with the projection optics and reducing cabling through the dashboard structure. Its support for embedded clocking and bidirectional I2C enables the HUD's brightness sensor and motor control loop to communicate back to the cluster MCU over the same link. AEC-Q100 Grade 2 and -40 C to +105 C operation handle windshield solar-load thermal conditions.
Recommended
Industrial Touch Panel and HMI Bridge
Industrial HMI panels often require a long-distance, EMI-robust video link between a sealed IPC enclosure and a remote touch-screen module on the factory floor. The DS90UH949TRGCTQ1's 5.95 Gbps serializer delivers 1080p content over 10+ meters of shielded twisted pair, while its industrial operating temperature range and integrated HDCP support make it suitable for medical imaging, secure KVM, and protected-content HMI terminals. The bidirectional I2C channel carries touch coordinates, button presses, and panel-status telemetry back to the host, eliminating a separate USB or RS-485 cable run.
Recommended
Medical Imaging Display Bridge
Diagnostic-grade medical displays (ultrasound, endoscopy, surgical monitors) need HDCP-protected, low-latency, noise-free video transport from imaging carts to ceiling-mounted or boom-arm displays. The DS90UH949TRGCTQ1's HDMI input accepts direct feed from medical graphics cards, and its serializer path preserves image fidelity without compression artifacts that would compromise diagnostic accuracy. The integrated bidirectional I2C pass-through enables remote calibration commands and panel self-test responses, while the AEC-Q100-derived robust silicon is well-suited to 24/7 hospital duty cycles across wide temperature ranges.
Recommended
Surveillance and Security Video Walls
Multi-display security video walls benefit from the DS90UH949TRGCTQ1's HDCP-protected HDMI input and FPD-Link III serialization to drive remote panels across long cable runs in NOC and control-room installations. A single HDMI source can be branched to multiple deserializer endpoints with synchronized audio/video, simplifying wall-controller architecture. The bidirectional control channel allows operator panels to query each display's health, brightness, and input status without a separate management network.

- Backwards-compatible FPD-Link II/III dual mode (vs DS90UB947TRGCRQ1)
- AEC-Q100 Grade 2 qualification with -40 C to +105 C operating range (vs DS90UB948TNKDRQ1)
Design Notes
The 64-VQFN (RGC) package relies on the exposed pad as its primary thermal path. The pad MUST be soldered to a continuous copper pour of at least 1 square inch on the top layer, with thermal vias (0.3 mm drill, 1 mm pitch) connecting to inner ground planes. Estimated: with a 4-layer 2 oz copper stack-up, theta_JA is approximately 28 C/W; with a minimal 1 oz 1-layer copper pour it rises to ~45 C/W. Derate the link accordingly if ambient inside a sealed head unit exceeds 85 C.
Route the FPD-Link III differential pair (TX0P/TX0N and RX1P/RX1N) with 100 ohm differential impedance, length-matched to within 5 mils, and AC-coupled with 0.1 uF 0402 capacitors placed within 5 mm of the serializer pins. Keep the HDMI input traces impedance-controlled at 90 ohm differential for the TMDS lanes, with reference ground on an adjacent layer and no splits under the data path. Place the 1.8 V and 3.3 V decoupling capacitors within 3 mm of each supply pin, using a 0.1 uF plus 10 uF bulk combination.
Do not assume the DS90UH949TRGCTQ1 and DS90UH949TRGCRQ1 are different parts - they share the same die and the only difference is the carrier-quantity code (T = 250-piece reel, R = 2000-piece reel). Common design mistakes include: (1) leaving the exposed pad un-soldered, which causes thermal shutdown under load; (2) omitting AC-coupling capacitors on the FPD-Link III output, which prevents link lock; (3) failing to configure MODE/IDX straps for the correct input interface (HDMI vs RGB) - check the datasheet's strap table before board bring-up.
Use a shielded twisted pair (STP) or coax cable rated for 5.95 Gbps operation; standard Ethernet Cat5e cable does NOT meet the loss budget beyond 3-5 meters. For 10+ meter automotive harnesses, specify a cable with <= 14 dB insertion loss at 3 GHz. Place ESD protection (low-capacitance TVS arrays) at the connector side to survive ISO 10605 automotive transients, with capacitance below 0.5 pF to preserve signal eye margin.
