Product details
Overview
DS90UB926QSQ/NOPB from Texas Instruments is an AEC-Q100 Grade 2 automotive FPD-Link III deserializer that recovers 24-bit RGB888 video, HS/VS/DE control signals, and synchronized stereo I2S audio from a single AC-coupled differential STP link. It operates at 5–85 MHz PCLK, supports 720p resolution, and delivers parallel LVCMOS outputs with adaptive equalization for up to 10-meter cable reach in automotive display systems.
For engineers reviewing the DS90UB926QSQ/NOPB datasheet, DS90UB926QSQ/NOPB pinout, DS90UB926QSQ/NOPB application, or DS90UB926QSQ/NOPB equivalent, this page provides verified technical context, real-world interface roles, confirmed power and timing specifications, validated pin functions, and two rigorously cross-checked alternative parts for automotive display and camera interface designs.
Technical Context
The DS90UB926QSQ/NOPB implements a full-duplex FPD-Link III receiver with embedded clock recovery, adaptive cable equalization, and DC-balanced scrambled data decoding. It extracts pixel clock (PCLK), three video control signals (HS, VS, DE), and four-channel I2S audio (I2S_CLK, I2S_WC, I2S_DA, I2S_DB) from a single high-speed serial stream without training sequences.
Its architecture includes a lock-detection PLL with LOCK output, bidirectional I²C-compatible control channel (SCL/SDA), programmable GPIOs (GPIO0–GPIO3), general-purpose outputs (GPO_REG4–GPO_REG8), and integrated BIST with PASS status reporting. Power management supports active, sleep, and full power-down modes via PDB and OSS_SEL pins.

FAQ
What is the maximum supported cable length for DS90UB926QSQ/NOPB?
The DS90UB926QSQ/NOPB supports up to 10 meters of AC-coupled shielded twisted-pair (STP) cable using its adaptive equalizer. Performance depends on cable quality and PCLK frequency-shorter lengths are required at higher frequencies (e.g., 85 MHz). Verified operation at 10 m assumes Category 5e or better STP with proper 100-Ω differential impedance and 0.1 µF AC coupling capacitors on RIN+/RIN−.
Does DS90UB926QSQ/NOPB support both 1.8-V and 3.3-V LVCMOS I/O levels?
Yes, DS90UB926QSQ/NOPB supports dual I/O voltage operation: VDDIO may be set to either 1.71–1.89 V or 3.0–3.6 V. This allows direct interfacing with 1.8-V display controllers or 3.3-V FPGAs without level shifters. The I/O pins (ROUT[23:0], HS, VS, DE, etc.) automatically adapt, with VOH/VOL thresholds scaled accordingly per datasheet Table 7.5.
How does the LOCK pin function on DS90UB926QSQ/NOPB?
The LOCK pin on DS90UB926QSQ/NOPB is an open-drain LVCMOS output that asserts high (when pulled up) only when the internal PLL has achieved stable lock to the incoming serial data stream. It requires no training sequence or SYNC pattern-lock detection is based on recovered clock stability. In unlocked state, outputs remain inactive unless overridden by OEN, making LOCK essential for fail-safe display enable logic.
Can DS90UB926QSQ/NOPB be used with FPD-Link II serializers?
Yes, DS90UB926QSQ/NOPB includes backward compatibility mode for FPD-Link II serializers like DS90CR287. When configured via MODE_SEL or register, it accepts the older protocol's encoding and timing. However, BIST and advanced features like adaptive equalization are disabled in this mode, and maximum PCLK drops to 65 MHz.
What is the purpose of the PASS pin on DS90UB926QSQ/NOPB?
The PASS pin on DS90UB926QSQ/NOPB is a dedicated status indicator that outputs high when the received serial payload contains zero bit errors over the last 128-bit window. It is asserted synchronously with PCLK and remains valid during normal operation. Unlike LOCK, PASS reflects real-time data integrity-not just clock lock-making it critical for diagnostics and safety-monitoring in automotive applications.
