The DS90CR218AMTD is an FPD-Link transmitter from National Semiconductor (now Texas Instruments), designed to transmit high-speed data over a single differential pair. It is part of the Channel Link family, commonly used for interconnecting displays and graphics controllers in various applications where high bandwidth and reduced cable size are essential. This particular part is designated as END-OF-LIFE by the manufacturer.

Applications

• Laptop and Notebook displays. Transmits video data from the graphics controller to the LCD panel.
• LCD monitors. Connects the graphics card to the display panel.
• Automotive infotainment systems. Used in in-car display systems for navigation and entertainment.
• Industrial displays. Facilitates data transmission in industrial control panels and instrumentation.
• Medical imaging equipment. Connects display components in medical diagnostic devices.

Features

• FPD-Link (Flat Panel Display Link) interface. Provides high-speed data transmission over a single differential pair.
• 24-bit RGB color data transmission. Supports a wide range of color depths.
• Pixel clock frequency up to 85 MHz. Enables high-resolution display support.
• Embedded clock. Eliminates the need for a separate clock signal.
• DC balanced transmission. Reduces EMI and improves signal integrity.
• Low power consumption. Minimizes power requirements in portable devices.
• Serialized data transmission. Reduces the number of interconnects required.

Benefits

Additional Details

The DS90CR218AMTD converts parallel RGB data into a serial data stream for transmission over the FPD-Link interface. It incorporates embedded clocking to further reduce the number of interconnects. The device's DC balanced transmission minimizes EMI and ensures signal integrity, even over longer cable lengths. This component is generally available in a TSSOP package. Note that because this part is END-OF-LIFE, availability might be limited, and replacements may be required for new designs. Consult the manufacturer's datasheet for detailed specifications, including voltage requirements, timing characteristics, and pinout information.
