  • Description

    The DS90C387A/DS90CF388A transmitter/receiver pair is designed to support dual pixel data transmission between Host and Flat Panel Display up to QXGA resolutions. The transmitter converts 48 bits (Dual Pixel 24-bit color) of CMOS/TTL data and 3 control bits into 8 LVDS (Low Voltage Differential Signalling) data streams. At a maximum dual pixel rate of 112MHz, LVDS data line speed is 784Mbps, providing a total throughput of 5.7Gbps (714 Megabytes per second).

    The LDI chipset is improved over prior generations of FPD-Link devices and offers higher bandwidth support and longer cable drive. To increase bandwidth, the maximum pixel clock rate is increased to 112 MHz and 8 serialized LVDS outputs are provided. Cable drive is enhanced with a user selectable pre-emphasis feature that provides additional output current during transitions to counteract cable loading effects.

    The DS90C387A transmitter provides a second LVDS output clock. Both LVDS clocks are identical. This feature supports backward compatibility with the previous generation of FPD-Link Receivers - the second clock allows the transmitter to interface to panels using a 'dual pixel' configuration of two 24-bit or 18-bit FPD-Link receivers.

    This chipset is an ideal means to solve EMI and cable size problems for high-resolution flat panel applications. It provides a reliable interface based on LVDS technology that delivers the bandwidth needed for high-resolution panels while maximizing bit times, and keeping clock rates low to reduce EMI and shielding requirements. For more details, please refer to the "Applications Information" section of this datasheet.

    Description:

    The LDI3V8BT-112 is an evaluation kit designed to demonstrate performance and capabilities of the DS90C387 and DS90CF388 and DS90C387A and DS90CF388A Open LDI Serializer/Deserializer Chipsets.

    The DS90C387 Serializer board accepts LVCMOS input signals and provides serialized FPD-Link LVDS data pairs as an output. The DS90CF388 Deserializer board accepts the FPD-Link LVDS serialized data streams and converts the data back into parallel LVCMOS signals and clock. Flat Ribbon cable is provided as a generic medium for the high speed data link. Jumpers and switches on the boards can be configured for evaluation of chipset features.

    Contents:

    • One Serializer board with IDC connectors on TX input with DS90C387
    • One Deserializer board with IDC connectors on RX output with DS90CF388
    • One 2- meter 3 M MDR LVDS Cable Interface
    • Evaluation Kit Documentation

    What the user needs to provide:

    • A source of RGB bus and clock - for example a video generator
    • LCD panel and interface from deserializer board to the panel itself, or a test equipment
    • Power supply for the both boards

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
