Hi Team,

Does DS90UB921-Q1 have a recommended maximum propagation delay/ Trace length for DPI input signals?

    Hello Elsa,

    We do not spec what cable length or propagation delay is incoming into the Serializer's input. However, if your signal fulfills our specifications, shown in the datasheet, such as:

    1) PCLK timing requirements (see datasheet section 6.8)

    2) Data input setup and hold time (see datasheet section 6.10)
