Texas Instruments DS90CR286AQMTX/NOPB

Overview

DS90CR286AQMTX/NOPB from Texas Instruments is a 28-bit LVDS-to-LVCMOS deserializer IC used as a high-speed parallel data receiver in display interface systems. It converts four LVDS data lanes plus one LVDS clock (20–66 MHz) into 28-bit 3.3-V LVCMOS parallel outputs - including 24-bit RGB and 4 control bits (HSYNC, VSYNC, DE, CNTL) - for driving TFT LCD panels. It features an internal PLL with no external components, <270 mW typical power at 66 MHz, and AEC-Q100 Grade 3 qualification.

For engineers reviewing the DS90CR286AQMTX/NOPB datasheet, DS90CR286AQMTX/NOPB pinout, DS90CR286AQMTX/NOPB application, or DS90CR286AQMTX/NOPB equivalent, key selection criteria include LVDS input skew margin (400 ps at 66 MHz), RxOUT setup/hold timing (4.5 ns / 4 ns min at 66 MHz), 56-pin TSSOP package compatibility, and support for automotive infotainment video links up to 1.848 Gbps.

Technical Context

The DS90CR286AQMTX/NOPB implements a Channel Link I-compliant receiver architecture with five LVDS differential inputs (four data + one clock), an integrated PLL for clock recovery, and a serial-to-parallel converter that maps each 7-bit LVDS symbol per clock cycle to seven LVCMOS output bits. Its phase-locked sampling ensures precise strobing on the rising edge of RxCLKOUT.

It operates across −40°C to +85°C with 3.0–3.6 V supply, supports 20–66 MHz LVDS clock rates, delivers 1.848 Gbps aggregate throughput, and includes active-low PWR DWN for sub-55 μA power-down mode. Input termination requires 100-Ω resistors per LVDS pair placed adjacent to pins 9–20 and 17–18.

FAQ

What is the maximum supported LVDS clock frequency for DS90CR286AQMTX/NOPB?

The DS90CR286AQMTX/NOPB supports LVDS clock frequencies from 20 MHz to 66 MHz. At 66 MHz, it achieves 1.848 Gbps aggregate throughput across four data lanes and delivers best-in-class timing margins - including 400 ps RxIN skew margin and 4.5 ns minimum setup time - making it ideal for high-resolution display interfaces.

Does DS90CR286AQMTX/NOPB require external components for PLL operation?

No, DS90CR286AQMTX/NOPB integrates a fully self-contained PLL with no external capacitors or resistors required. This simplifies layout, reduces bill-of-materials cost, and eliminates tuning steps - the PLL locks automatically to incoming LVDS clock frequencies between 20 MHz and 66 MHz.

How many LVDS differential inputs does DS90CR286AQMTX/NOPB have?

DS90CR286AQMTX/NOPB has five LVDS differential inputs: four for serialized data (RxIN0± through RxIN3±) and one for the LVDS clock (RxCLKIN±). Each differential pair requires a 100-Ω termination resistor placed adjacent to the IC pins to ensure signal integrity and minimize reflections.

What is the function of the PWR DWN pin on DS90CR286AQMTX/NOPB?

The PWR DWN pin on DS90CR286AQMTX/NOPB is an active-low control input that places the device into ultra-low-power mode (<55 μA) when asserted. In this state, all RxOUT outputs are driven low, and internal circuitry enters standby - enabling power gating in automotive display gateways and portable medical devices.

Is DS90CR286AQMTX/NOPB qualified for automotive applications?

Yes, DS90CR286AQMTX/NOPB is AEC-Q100 Grade 3 qualified (−40°C to +85°C), making it suitable for automotive cabin applications including digital instrument clusters and infotainment displays. It meets stringent reliability, ESD (±7 kV HBM), and thermal performance requirements defined by the automotive standard.
