Product details
Overview
DS90UH928QSQE/NOPB from Texas Instruments is an automotive-grade FPD-Link III deserializer IC that converts high-speed serialized video/audio with embedded clock over a single AC-coupled STP pair into four LVDS data streams, one LVDS clock (OpenLDI), and up to four I2S audio outputs. It supports 5–85 MHz pixel clocks, RGB888 + HS/VS/DE timing, HDCP 1.3 content protection, and operates from -40°C to +105°C. Used in automotive navigation displays and rear-seat entertainment systems.
For engineers reviewing the DS90UH928QSQE/NOPB datasheet, DS90UH928QSQE/NOPB pinout, DS90UH928QSQE/NOPB application, or DS90UH928QSQE/NOPB equivalent, key selection criteria include HDCP repeater capability, adaptive cable equalization for ≤10 m STP interconnects, dual-supply flexibility (VDD33 = 3.3 V, VDDIO = 1.8 V or 3.3 V), LVDS output compliance (100 Ω termination), and AEC-Q100 Grade 2 qualification.
Technical Context
The DS90UH928QSQE/NOPB implements a fully integrated HDCP cipher engine with on-chip key storage and supports HDCP repeater functionality via bidirectional control channel. Its FPD-Link III receiver includes adaptive input equalization to compensate for transmission losses and deterministic jitter across long cables.
It delivers four LVDS data pairs (TxOUT[3:0]±), one LVDS clock pair (TxCLKOUT±), and four independent I2S audio outputs (I2S_DA/DB/DC/DD) with MCLK, I2S_CLK, and I2S_WC - all configurable via I²C (SDA/SCL) and register-accessible GPIOs. The device supports backward-compatible modes (BKWD, REPEAT) and image enhancement features including white balance and dithering.

FAQ
What is the primary function of the DS90UH928QSQE/NOPB in an automotive video system?
The DS90UH928QSQE/NOPB functions as an FPD-Link III deserializer that receives high-speed serialized video and audio over a single differential pair, then outputs parallel LVDS video (OpenLDI compliant) and up to four I2S audio streams. It integrates HDCP 1.3 encryption/decryption and supports AEC-Q100 Grade 2 operation for use in automotive navigation and rear-seat displays.
Does the DS90UH928QSQE/NOPB support HDCP repeater functionality?
Yes, the DS90UH928QSQE/NOPB supports HDCP repeater mode, allowing it to act as an intermediate node in a content distribution chain. This capability is enabled via dedicated control registers and requires pairing with a compatible FPD-Link III serializer such as DS90UH927Q-Q1. The on-chip HDCP cipher engine stores keys internally and handles authentication handshaking.
What are the power supply requirements for the DS90UH928QSQE/NOPB?
The DS90UH928QSQE/NOPB requires two supplies: VDD33 (3.0–3.6 V) for core logic and LVDS drivers, and VDDIO (1.71–1.89 V or 3.0–3.6 V) for LVCMOS I/Os. Each supply needs a 4.7 µF decoupling capacitor. Power-up ramp must be monotonic and faster than 1.5 ms; PDB must be driven high to enable normal operation.
Can the DS90UH928QSQE/NOPB drive standard LVDS displays directly?
Yes, the DS90UH928QSQE/NOPB outputs four LVDS data pairs and one LVDS clock pair compliant with OpenLDI (FPD-Link) standards. These outputs require external 100 Ω differential termination and deliver RGB888 pixel data with HS, VS, and DE timing signals - directly compatible with most automotive LVDS display panels.
How does the DS90UH928QSQE/NOPB handle long cable runs in automotive harnesses?
The DS90UH928QSQE/NOPB incorporates adaptive input equalization optimized for AC-coupled STP cables up to 10 meters. It compensates for frequency-dependent loss and deterministic jitter introduced by long harnesses, maintaining signal integrity without requiring external equalizer ICs or complex PCB layout adjustments.
