Product details
Overview
DS90UH927QSQE/NOPB from Texas Instruments is an automotive-grade FPD-Link III serializer IC that converts 24-bit RGB888 video + HS/VS/DE + I2S audio into a single AC-coupled differential serial stream for transmission over STP cable up to 10 meters. It supports 5–85 MHz pixel clock, HDCP encryption, and operates from 3.3-V supply with 1.8-V or 3.3-V LVCMOS I/O interface.
For engineers reviewing the DS90UH927QSQE/NOPB datasheet, DS90UH927QSQE/NOPB pinout, DS90UH927QSQE/NOPB application, or DS90UH927QSQE/NOPB equivalent, this page delivers verified technical context, exact pin functions, real-world automotive display use cases, and two confirmed alternative serializers with documented functional differences.
Technical Context
The DS90UH927QSQE/NOPB implements a full FPD-Link III forward-channel serializer with embedded HDCP cipher engine, DC-balanced scrambling, and clock embedding. It accepts parallel LVDS video inputs (RxIN[3:0]±, RxCLKIN±) and I2S audio (I2S_DA–I2S_WC), then outputs a CML differential stream (DOUT±) at up to 2.56 Gbps.
It features bidirectional I²C control (SDA/SCL), four GPIOs, backward compatibility modes (BKWD), low-frequency mode (LFMODE), and repeater functionality (REPEAT). Power management includes PDB-controlled shutdown with <2.4 mA standby current and dual-supply support (VDD33 = 3.3 V, VDDIO = 1.8 V or 3.3 V).
Key Specifications

Yes. DS90UH927QSQE/NOPB supports dual VDDIO operation: 1.71–1.89 V for 1.8-V LVCMOS I/Os or 3.0–3.6 V for 3.3-V interfaces. Pin-level VIH/VIL thresholds scale accordingly, as detailed in Section 6.5 of SNLS433C.
How does DS90UH927QSQE/NOPB handle power-down and wake-up timing?
When PDB is driven low, DS90UH927QSQE/NOPB enters power-down mode with <2.4 mA supply current and resets internal registers. PLL lock time after wake-up is ≤5 ms (tPLD), verified per Section 6.6 AC Electrical Characteristics in SNLS433C.
Is DS90UH927QSQE/NOPB pin-compatible with DS90UH927Q-Q1?
