    Hello,
    Is your question on the TFP403 receiver side or the C387A transmit side? Have you looked at the product documentation online? The C387A datasheet provides information on how to configure for both single pixel and dual pixel modes.

    Hi,

    We are using DS90C387A at transmit side.

    We are refer the following two application notes. It makes confusion.

    1. SLLA325A

    2. SNLA014

    So Please suggest the single channel LVDS connection for DS90C387A at transmit side.

    Hi, can you list what your confusion for this application?
    for 387A, please see d/s for single pixel application as below. this is one Serializer, the parallel inputs are serialized in the LVDS output.

    Dual Pin: Three-mode select for dual pixel, single pixel, or single pixel input to dual
    pixel output operation. Single pixel mode when input is low (only LVDS
    channels A0 thru A3 and CLK1 are active) for power savings. Dual mode is
    active when input is high. Single in - dual out when input is at 1/2 Vcc. (Note
    10)

    best regards,
    Steven
