Texas Instruments DS90CF364AMTD

Overview

DS90CF364AMTD from Texas Instruments is an 18-bit Flat Panel Display (FPD) Link LVDS receiver that converts three LVDS data streams into parallel TTL/CMOS outputs (6R+6G+6B+HSYNC/VSYNC/DE), operates at 20–65 MHz clock rates, consumes ≤90 mA typical supply current at 65 MHz, and features falling-edge strobe output clock with 50% duty cycle - deployed in embedded LCD timing controllers for industrial panel PCs.

For engineers reviewing the DS90CF364AMTD datasheet, DS90CF364AMTD pinout, DS90CF364AMTD application, or DS90CF364AMTD equivalent, this page delivers verified technical context, package-validated pin functions, real-world FPD Link interface constraints, and substitution guidance grounded in TI's SNLS040I specification.

Technical Context

The DS90CF364AMTD implements a PLL-based LVDS-to-TTL conversion architecture with internal data sampling window defined by RSPos timing parameters (e.g., 0.7–1.4 ns at 65 MHz for Bit 0), supporting interoperability with falling-edge strobe transmitters like DS90C363A without translation logic. Its receiver input skew margin (RSKM) is 500 ps at 65 MHz, accommodating interconnect skew and <250 ps cycle-to-cycle jitter.

It integrates separate power domains: LVDS VCC/GND for differential inputs, PLL VCC/GND for phase-locked loop circuitry, and VCC/GND for 21 CMOS/TTL outputs - enabling noise isolation between analog receive path and digital output stage while maintaining 3.0–3.6 V supply tolerance.

Key Specifications

Pinout & Package

FAQ

What is the maximum supported pixel clock frequency for DS90CF364AMTD?

The DS90CF364AMTD supports shift clock frequencies from 20 MHz to 65 MHz per the SNLS040I datasheet. At 65 MHz, it achieves 1.3 Gbps aggregate data throughput, sufficient for XGA (1024×768) resolution at 60 Hz with standard blanking intervals. Operation beyond 65 MHz is not characterized or guaranteed.

Does DS90CF364AMTD require external components for PLL operation?

No, DS90CF364AMTD integrates a complete PLL with no external components required - its loop filter is fully internal. This eliminates the need for external capacitors or resistors, reducing bill-of-materials cost and PCB area while ensuring consistent lock time (10 ms typical RPLLS) across units and temperatures.

How does the power-down mode function on DS90CF364AMTD?

When the PWR DOWN pin is driven low, DS90CF364AMTD enters power-down mode drawing ≤55 μA supply current (ICCRZ), and all 21 RxOUT pins are actively held low. Exit delay is 1 μs (RPDD), enabling rapid wake-up for dynamic display brightness control or multi-panel power sequencing in industrial HMIs.

What is the meaning of "falling-edge strobe" in DS90CF364AMTD's RxCLK OUT specification?

DS90CF364AMTD's RxCLK OUT signal uses the falling edge as the data valid strobe - meaning downstream logic must sample RxOUT[0:20] on the clock's falling transition. This matches TI's DS90C363A transmitter and avoids need for edge inversion logic, preserving timing margin and reducing jitter accumulation in the FPD Link chain.

Can DS90CF364AMTD interface directly with a 24-bit RGB LCD panel?

No, DS90CF364AMTD provides only 18-bit RGB output (6R+6G+6B) plus HSYNC/VSYNC/DE - insufficient for native 24-bit panels requiring 8-bit per channel. For 24-bit support, TI's DS90CF384AMTD (24-bit + CNTL) or SN75LVDS83B are required alternatives, though neither shares pin compatibility with DS90CF364AMTD.
