DS90UB947-Q1: Setup time and hold Time ?

Part Number: DS90UB947-Q1

hi  Team:

How to determine the Setup time and hold Time ?

Tks!

  • Hi,

    OpenLDI is also serdes I/f, not strict request on setup/hold timing. pls check d/s on the LVDS_CLK and LVDS_Data relationship as below.

    8.3.4 OpenLDI Input Frame And Color Bit Mapping Select
    The DS90UB947-Q1 can be configured to accept 24-bit color (8-bit RGB) with 2 different mapping schemes,
    shown in Figure 13 and Figure 14. Each frame corresponds to a single pixel clock (PCLK) cycle. The LVDS clock
    input to CLK± follows a 4:3 duty cycle scheme, with each 28-bit pixel frame starting with two LVDS bit clock
    periods high, three low, and ending with two high. The mapping scheme is controlled by MAPSEL strap option or
    by Register (Table 10).
