Product details
Overview
DS90UH927QSQ/NOPB from Texas Instruments is an automotive-grade FPD-Link III serializer IC that converts 24-bit RGB888 video with VS/HS/DE and up to four I2S audio channels into a single AC-coupled differential serial stream for transmission over STP cable. It operates from 5 MHz to 85 MHz PCLK, supports 720p resolution, embeds HDCP cipher engine with on-chip key storage, and interfaces directly to graphics processors via LVCMOS or LVDS parallel inputs.
For engineers reviewing the DS90UH927QSQ/NOPB datasheet, DS90UH927QSQ/NOPB pinout, DS90UH927QSQ/NOPB application, or DS90UH927QSQ/NOPB equivalent, this page delivers verified technical context, validated pin functions, confirmed HDCP repeater capability, real-world 10-meter STP interconnect support, and precise AEC-Q100 Grade 2 compliance details - all grounded in TI's SNLS433C datasheet.
Technical Context
The DS90UH927QSQ/NOPB implements a full-duplex FPD-Link III interface with embedded clock recovery, DC-balanced scrambling, and bidirectional control channel over the same differential pair. Its serializer core accepts parallel RGB888 + sync signals and up to four I2S audio streams, then multiplexes them with HDCP-encrypted payload before CML-level serialization.
It features dual-supply operation (3.3-V VDD33 for internal regulation and 1.8-V/3.3-V VDDIO for LVCMOS I/O), supports backward compatibility with DS90UH926/928Q-Q1, and includes configurable modes via LFMODE, MAPSEL, REPEAT, and BKWD pins - enabling low-frequency operation (5–15 MHz), MSB/LSB data mapping, HDCP repeater function, and legacy interface alignment.

Does the DS90UH927QSQ/NOPB support HDCP repeater functionality?
Yes, the DS90UH927QSQ/NOPB supports HDCP repeater mode via the REPEAT pin. When asserted, it regenerates and re-encrypts HDCP content, allowing cascaded display topologies while maintaining end-to-end compliance with HDCP 1.4. This capability is confirmed in TI's SNLS433C datasheet Section 7.4 and Feature Description.
What are the valid supply voltage configurations for DS90UH927QSQ/NOPB?
The DS90UH927QSQ/NOPB requires two supplies: VDD33 (3.0–3.6 V) for internal regulation and VDDIO (1.71–1.89 V or 3.0–3.6 V) for LVCMOS I/O. The VDDIO pins support either 1.8-V or 3.3-V logic levels, enabling direct interfacing with diverse graphics processors - a specification verified in Section 6.3 of the SNLS433C datasheet.
How does the DS90UH927QSQ/NOPB handle clock embedding and jitter tolerance?
The DS90UH927QSQ/NOPB embeds the pixel clock within the serialized data stream using CML signaling and achieves <0.29 UI total jitter at 85 MHz PCLK. Its input jitter tolerance is 0.5 UI for 78-MHz input clocks when paired with DS90UH928Q-Q1, as specified in Section 6.6 of SNLS433C - ensuring robust timing integrity across automotive temperature ranges.
