Texas Instruments DS90UR916QSQ/NOPB

Overview

DS90UR916QSQ/NOPB from Texas Instruments is an automotive-grade FPD-Link II deserializer that recovers 24-bit RGB888 video, HS/VS/DE control signals, and pixel clock from a single AC-coupled differential pair at 5–65 MHz PCLK (140 Mbps–1.82 Gbps). It features white balance LUTs, adaptive Hi-FRC dithering, and real-time LOCK status reporting. Designed for in-vehicle display interfaces, it supports QVGA to XGA resolution displays with up to 10-meter STP cable.

For engineers reviewing the DS90UR916QSQ/NOPB datasheet, DS90UR916QSQ/NOPB pinout, DS90UR916QSQ/NOPB application, or DS90UR916QSQ/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification (−40°C to +105°C), LVCMOS I/O voltage flexibility (1.8 V or 3.3 V), integrated receiver equalization, SSCG support, and backward compatibility with DS90UR241 and DS90C241 serializers.

Technical Context

The DS90UR916QSQ/NOPB implements embedded-clock recovery without external reference clock or training sequences, achieving FAST Random Data Lock. Its DC-balanced decoding enables reliable AC-coupled interconnects over 10-meter STP cables. The internal PLL locks to incoming serial data across the full 5–65 MHz PCLK range, with lock time as low as 3 ms (no SSCG) or 6 ms (with SSCG at 65 MHz).

It integrates configurable image enhancement: dual-stage FRC dithering and programmable white balance LUTs. Output slew control (OS_PCLK/DATA), spread-spectrum clocking (SSCG), and adjustable input equalization (EQ[3:0]) allow system-level EMI and signal integrity tuning. The device operates with independent 1.8 V supply domains (VDDL, VDDIR, VDDR, VDDSC, VDDPR, VDDCMLO) and flexible 1.8 V/3.3 V LVCMOS I/O (VDDIO).

FAQ

What is the maximum cable length supported by DS90UR916QSQ/NOPB?

The DS90UR916QSQ/NOPB supports AC-coupled STP interconnect cables up to 10 meters in length when paired with the DS90UR905Q serializer. Performance depends on cable quality and equalization setting: EQ[3:0] straps allow compensation for higher loss, and actual reach may extend beyond 10 m with optimized 100 Ω shielded twisted-pair and proper grounding. DS90UR916QSQ/NOPB datasheet Figure 1 confirms 10 m as the validated specification.

Does DS90UR916QSQ/NOPB require an external reference clock?

No, DS90UR916QSQ/NOPB does not require an external reference clock. It performs embedded clock recovery directly from the incoming FPD-Link II serial stream using its internal PLL, enabling "FAST Random Data Lock" without training sequences or SYNC patterns. This eliminates clock distribution complexity and skew issues in automotive display systems. DS90UR916QSQ/NOPB achieves lock in as little as 3 ms at 5 MHz PCLK.

How does DS90UR916QSQ/NOPB handle video control signals (HS, VS, DE)?

DS90UR916QSQ/NOPB recovers HS, VS, and DE from the embedded FPD-Link II stream and outputs them as LVCMOS timing signals synchronized to the recovered PCLK. Pulse width and transition rate are constrained: e.g., HS requires ≥3 PCLKs when CONFIG[1:0]=01 (control filter enabled), and VS is limited to 1 transition per 130 PCLKs. These constraints ensure robust transmission of control data alongside high-speed RGB.

Can DS90UR916QSQ/NOPB operate with both 1.8 V and 3.3 V I/O supplies?

Yes, DS90UR916QSQ/NOPB supports dual-voltage LVCMOS I/O: VDDIO may be set to either 1.8 V ±5% or 3.3 V ±10%. DC specifications are guaranteed for both rails-e.g., VOH ≥2.4 V at 3.3 V, and VOH ≥VDDIO −0.45 V at 1.8 V. This allows direct interfacing with 1.8 V display drivers or 3.3 V FPGA I/O banks without level shifters. DS90UR916QSQ/NOPB datasheet Section 7.5 confirms both operating modes.

What is the purpose of the LOCK pin on DS90UR916QSQ/NOPB?

The LOCK pin on DS90UR916QSQ/NOPB is a real-time status indicator: LOCK = 1 signifies stable PLL lock and valid parallel outputs (RGB/HS/VS/DE/PCLK); LOCK = 0 indicates unlocked state, where outputs enter tri-state or low state per OSS_SEL/PDB configuration. It is used for display enable synchronization, system diagnostics, and fail-safe shutdown. DS90UR916QSQ/NOPB pin description Table 1 explicitly defines LOCK as "PLL is Locked" status output.
