Product details
Overview
DS90UR907QSQX/NOPB from Texas Instruments is an automotive-grade FPD-Link to FPD-Link II serializer IC that converts 4-channel LVDS data + 1-channel LVDS clock (RGB888 + VS/HS/DE) into a single-pair high-speed serial stream. It operates from 5 MHz to 65 MHz pixel clock, supports 24-bit color depth, embeds DC-balanced encoding and scrambling, and delivers ≤0.26 UI total output jitter at 65 MHz for QVGA–XGA displays in automotive navigation and infotainment systems.
For engineers reviewing the DS90UR907QSQX/NOPB datasheet, DS90UR907QSQX/NOPB pinout, DS90UR907QSQX/NOPB application, or DS90UR907QSQX/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification, configurable VOD (±300 mV / ±450 mV), pin-selectable de-emphasis, backward compatibility with DS90C124/DS90UR124, and support for AC-coupled STP cables up to 10 meters.
Technical Context
The DS90UR907QSQX/NOPB implements a deterministic parallel-to-serial conversion architecture with integrated PLL, DC-balance encoder, and scrambler. It accepts five LVDS inputs (RxIN[3:0]±, RxCLKIN±), applies 8b/10b-like balancing and pseudo-random scrambling, and outputs a single differential LVDS pair (DOUT±) carrying embedded clock, video data, and control signals.
Its functional modes-controlled via CONFIG[1:0], MAPSEL, and VODSEL pins-define deserializer compatibility (DS90UR908Q, DS90UR124, or DS90C124), RGB bit mapping (LSB/MSB on RxIN3), and signal integrity tuning. The device supports optional I²C configuration (SCL/SDA), BIST mode (BISTEN), and power-down (PDB) with <1 µA IDDZ at 1.8 V.

FAQ
What is the primary function of the DS90UR907QSQX/NOPB?
The DS90UR907QSQX/NOPB is an FPD-Link to FPD-Link II serializer IC that converts 4 LVDS data lanes and 1 LVDS clock lane (RGB888 + VS/HS/DE) into a single high-speed serial differential pair. It enables compact, low-EMI, long-cable display interconnects in automotive applications and is fully compatible with DS90UR908Q deserializers. Its core function is deterministic parallel-to-serial conversion with DC balancing and scrambling.
Does DS90UR907QSQX/NOPB support backward compatibility with older deserializers?
Yes, DS90UR907QSQX/NOPB supports backward compatibility through hardware-configurable CONFIG[1:0] pins. Setting CONFIG[1:0] = 10 enables interoperability with DS90UR124 (FPD-Link II Gen2), and CONFIG[1:0] = 11 enables operation with DS90C124 (FPD-Link II Gen1). This allows reuse of existing deserializer hardware in legacy automotive display modules without redesign.
How does the VODSEL pin affect DS90UR907QSQX/NOPB performance?
The VODSEL pin on DS90UR907QSQX/NOPB selects differential output voltage: logic high sets ±450 mV (900 mVp-p) for long cable runs with higher loss, while logic low sets ±300 mV (600 mVp-p) for shorter, lower-loss interconnects. This direct hardware control eliminates need for register writes and ensures optimal signal integrity across variable harness lengths in automotive platforms.
What is the role of the BISTEN pin on DS90UR907QSQX/NOPB?
The BISTEN pin enables Built-In Self-Test mode on DS90UR907QSQX/NOPB. When asserted high, it activates at-speed link testing using internal pattern generation and error detection-verifying physical layer integrity without external test equipment. This capability accelerates production line validation and supports field diagnostics in automotive display systems.
Can DS90UR907QSQX/NOPB operate with both 1.8 V and 3.3 V I/O supplies?
Yes, DS90UR907QSQX/NOPB supports dual-voltage I/O: VDDIO accepts either 1.8 V ±5% or 3.3 V ±10%, allowing flexible interfacing with host GPUs or MCUs operating at either logic level. All LVCMOS control pins (PDB, VODSEL, CONFIG[1:0], etc.) are compatible with both voltages, simplifying system-level voltage domain management.
