Texas Instruments DS90UR906QSQ/NOPB

Overview

DS90UR906QSQ/NOPB from Texas Instruments is an automotive-grade FPD-Link II deserializer IC that recovers 24-bit RGB video, HS/VS/DE control signals, and embedded pixel clock from a single AC-coupled differential serial stream. It operates at 5–65 MHz PCLK (140 Mbps–1.82 Gbps), supports up to 10 m STP cable, and delivers real-time LOCK status reporting. Used in automotive navigation and infotainment displays.

For engineers reviewing the DS90UR906QSQ/NOPB datasheet, DS90UR906QSQ/NOPB pinout, DS90UR906QSQ/NOPB application, or DS90UR906QSQ/NOPB equivalent, key selection criteria include AEC-Q100 Grade 2 qualification, 1.8 V/3.3 V LVCMOS I/O compatibility, integrated receiver equalization, spread-spectrum clocking support, and lock-detection capability without reference clock or training sequence.

Technical Context

The DS90UR906QSQ/NOPB implements a PLL-based clock recovery architecture with no external reference clock required, achieving fast random-data lock via adaptive equalization on the RIN± inputs. Its internal DC-balanced decoding enables robust AC-coupled operation over STP cables.

It features configurable output slew control (OS_PCLK/OS_DATA), programmable SSCG range (SSC[3:0]), and strap-selectable receiver equalization (EQ[3:0]) and bit mapping (MAP_SEL[1:0]). The LOCK pin provides real-time link integrity monitoring, while PASS reports BIST error status.

FAQ

What is the maximum supported cable length for DS90UR906QSQ/NOPB?

The DS90UR906QSQ/NOPB supports AC-coupled STP interconnect cables up to 10 meters in length when paired with the DS90UR905Q-Q1 serializer. This is achieved through adjustable receiver equalization (EQ[3:0]) and optimized LVDS input sensitivity, enabling reliable operation at 65 MHz PCLK over standard automotive shielded twisted-pair cabling.

Does DS90UR906QSQ/NOPB require an external reference clock?

No, DS90UR906QSQ/NOPB does not require an external reference clock. It performs fully autonomous clock recovery from the incoming FPD-Link II serial stream using an internal PLL architecture. Lock acquisition occurs rapidly on random data without training sequences, and the LOCK pin provides real-time confirmation of stable synchronization.

How is the DS90UR906QSQ/NOPB configured for different serializer partners?

DS90UR906QSQ/NOPB uses CONFIG[1:0] strap pins to select compatibility mode: CONFIG[1:0]=00 or 01 enables interoperability with DS90UR905Q-Q1 (with/without control signal filtering), while 10/11 selects DS90UR241 or DS90C241. These settings determine register mapping, timing behavior, and handshake protocols - no firmware change is needed.

What power supply voltages does DS90UR906QSQ/NOPB support?

DS90UR906QSQ/NOPB supports dual-domain I/O: VDDIO accepts either 1.8 V ±5% or 3.3 V ±10%, allowing direct connection to host processors with either voltage level. Core supplies (VDDL, VDDPR, VDDIR, VDDCMLO, VDDR, VDDSC) all operate at 1.8 V ±5%, with strict monotonic ramp requirements (<1.5 ms) for reliable power-up sequencing.

Can DS90UR906QSQ/NOPB generate spread-spectrum clocking?

Yes, DS90UR906QSQ/NOPB supports hardware-configurable spread-spectrum clock generation (SSCG) on its parallel outputs. The SSC[3:0] strap pins select one of 16 modulation ranges, reducing peak radiated emissions without requiring software control - critical for meeting automotive EMC standards like CISPR 25 Class 5.
