Texas Instruments DS90CF384AQMTX/NOPB

Overview

DS90CF384AQMTX/NOPB from Texas Instruments is an automotive-grade LVDS receiver IC for FPD-Link applications, converting four LVDS data streams into 28-bit parallel LVCMOS/LVTTL output (24-bit RGB + 4 control) at up to 65 MHz clock rate and 1.8 Gbps aggregate throughput. It operates from 3.3 V, delivers 50% duty-cycle RxCLK OUT, and supports VGA–Dual Pixel SXGA displays in flat-panel timing controller interfaces.

For engineers reviewing the DS90CF384AQMTX/NOPB datasheet, DS90CF384AQMTX/NOPB pinout, DS90CF384AQMTX/NOPB application, or DS90CF384AQMTX/NOPB equivalent, key selection criteria include AEC-Q100 Grade 3 qualification, −40°C to +85°C operation, low-power receiver mode (<142 mW @65 MHz), precise setup/hold timing (RSRC = 4.5–7.3 ns), and TSSOP-56 package compatibility with high-density display interconnects.

Technical Context

The DS90CF384AQMTX/NOPB implements a PLL-based LVDS-to-LVCMOS conversion architecture with no external components required. Its internal data sampling window is defined by receiver input strobe positions (RSPos0–RSPos6) ranging from 0.7 ns to 14.6 ns across 25–65 MHz, enabling robust skew margin (RSKM = 500–750 ps) against cable-induced jitter and ISI.

It features dedicated LVDS and PLL power domains (LVDS VCC, PLL VCC, VCC), independent ground pins (LVDS GND ×3, PLL GND ×2, GND ×5), and TTL-level control signaling including PWR DOWN for <200 μW power-down mode. Output timing is referenced to RxCLK OUT falling edge as data strobe per FPD-Link convention.

FAQ

What is the primary function of the DS90CF384AQMTX/NOPB in a display system?

The DS90CF384AQMTX/NOPB functions as an LVDS-to-parallel converter that recovers four serialized LVDS data streams and one LVDS clock into 28-bit LVCMOS/LVTTL parallel output-comprising 24-bit RGB video data and up to 4 control signals (HSYNC, VSYNC, DE, CNTL). It enables high-speed, low-EMI video transmission between timing controllers and LCD panels. The DS90CF384AQMTX/NOPB achieves this with integrated PLL clock recovery and guaranteed timing margins across its full 20–65 MHz operating range.

Does the DS90CF384AQMTX/NOPB require external components for PLL operation?

No, the DS90CF384AQMTX/NOPB integrates a fully self-contained PLL that requires no external capacitors, resistors, or crystals. Its PLL locks directly to the incoming LVDS clock (RxCLK IN±) and generates the synchronized RxCLK OUT signal used to strobe the 28-bit parallel outputs. This simplifies board layout, reduces BOM count, and improves reliability-key advantages confirmed in TI's SNLS345A datasheet for the DS90CF384AQMTX/NOPB.

How does the DS90CF384AQMTX/NOPB support automotive applications?

The DS90CF384AQMTX/NOPB is explicitly qualified to AEC-Q100 Grade 3 standards, covering operation from −40°C to +85°C ambient temperature, robust ESD protection (>7 kV HBM), and validated reliability for automotive infotainment and instrument cluster use. Its low 142 mW typical power consumption at 65 MHz and precise timing parameters (e.g., 4.5–7.3 ns RxOUT setup time) ensure stable pixel delivery in thermally constrained vehicle cabins. These attributes are specified and tested for the DS90CF384AQMTX/NOPB per TI's production data.

What is the meaning of "PWR DOWN" functionality on the DS90CF384AQMTX/NOPB?

The PWR DOWN pin on the DS90CF384AQMTX/NOPB is an active-low control input that places the device into ultra-low-power mode (<200 μW max), driving all 28 RxOUT signals low and disabling internal circuitry except bias references. This feature enables display blanking, power gating during sleep states, or synchronization with system-level power management. The DS90CF384AQMTX/NOPB specifies RPDD (power-down delay) as 1 μs, ensuring rapid entry/exit from this state without disrupting video timing integrity.

Can the DS90CF384AQMTX/NOPB be used with non-TI FPD-Link transmitters?

Yes, the DS90CF384AQMTX/NOPB is compatible with any TIA/EIA-644-compliant LVDS transmitter operating within its 20–65 MHz shift clock range and 1.8 Gbps aggregate data rate limit. While optimized for TI's DS90C383B transmitter, its input specifications-including differential input thresholds (±100 mV), common-mode range (0–2.4 V), and skew margin (500 ps @65 MHz)-support interoperability with third-party FPD-Link sources. This compatibility is verified in the DS90CF384AQMTX/NOPB's electrical characteristics and AC timing tables.
