The DS90CF582MTDX is a Flat Panel Display Link (FPD-Link) transmitter designed for high-speed data transmission from a graphics controller to a flat panel display. This transmitter, manufactured by National Semiconductor (now Texas Instruments), converts parallel RGB data into a serial data stream for transmission over a single cable, reducing the interconnect complexity and cost associated with traditional parallel interfaces.

Applications

• LCD monitors
• Laptop displays
• Digital televisions
• Industrial displays
• Automotive displays

Features

• FPD-Link Interface: Supports high-speed serial data transmission using the FPD-Link protocol.
• 24-bit RGB Input: Accepts 24-bit RGB parallel data from the graphics controller.
• Pixel Clock Support: Supports pixel clock frequencies up to 85 MHz.
• Serialized Data Output: Converts the parallel data into a serial data stream for transmission over a twisted pair cable.
• Reduced EMI: Serial data transmission reduces electromagnetic interference compared to parallel interfaces.
• Power-Down Mode: Features a power-down mode for reduced power consumption during inactive periods.
• Small Package: Available in a compact TSSOP package for space-constrained applications.

Benefits

• Simplified System Design: Reduces the number of interconnects required between the graphics controller and the display.
• Lower System Cost: Reduces cable cost and connector cost.
• Improved Signal Integrity: Serial data transmission minimizes signal skew and reduces signal degradation.
• Reduced EMI: Lowers electromagnetic interference, improving overall system performance and reliability.
• Lower Power Consumption: Power-down mode reduces power consumption, extending battery life in portable devices.

Additional Details

The DS90CF582MTDX uses a current mode logic (CML) output driver to transmit the serial data over a twisted pair cable. The device typically operates from a 3.3V power supply. It incorporates an internal phase-locked loop (PLL) to generate the high-speed serial clock from the pixel clock input. The FPD-Link interface provides a robust and reliable data transmission solution for flat panel display applications.
