TDA4VE-Q1: SPI Interface Issue

Part Number: TDA4VE-Q1

Dear TI expert.

We use TDA4VE as our project solution and connect the SPI0 interface to UPID(DSI3) directly.

The SPI_CLK Frequency is 10MHz.

And according to the HW test, we found that the Tdis time can't meet the requirement from datasheet. The Tdis = 24.2uS/42.6uS(two samples) and which value from Datasheet is maximum 200nS. How can we meet this requirement? Can we just change the Tdis via setting the register?

    Hi Jinzhong,

    I have a few questions:

    1. Are you running into functional issues? 
    2. Where is this requirement being defined? The attached screenshots do not appear to reflect our datasheet.
    3. How are you performing this measurement? Can you provide the plots?
