DS90C387A: DS90C387A related issues

Part Number: DS90C387A

Tool/software:

Hello,

The customer wants to use a DS90C387A chip to output dual LVDS (10 pairs) and simultaneously light up two screens. May I ask if it can be achieved? If it can be achieved, how can it be achieved? Do you have any examples to refer to?

Thanks!

  • Hi Jeno,

    Could you please confirm the block diagram for this system, to confirm the input and output interfaces from the IC?

    It appears you would use dual LVDS (4 Data channels + 1 CLK pair) for each display. Examining the number of data channels used, this would be 24 bpp?

    Based on the generalized block diagram, separate parallel RGB888 inputs (1 and 2) would come into the IC, and separate LVDS outputs would go out. Please note the PLL is common between the LVDS outputs.

    This configuration sounds feasible as long as the assumptions below are met:

    • Both displays share the same RX Clocking rate
    • Separate CMOS/TTL is supplied for each display at the ICs input
    • Bandwidth is met at the 195 to 784 Mbit/s LVDS channel output

    If you have more information about the display application or can form a block diagram to describe, this will confirm some of the assumptions above.

    Please let me know if you have any additional questions or feedback!

    Best,

    Miguel
