DS90UH925Q-Q1: FPDlink signal integrity test method

Part Number: DS90UH925Q-Q1


Hi champ,

We have a customer Roadrover, they use the 925-926 in infotainment system.

Now they have doubt about the FPDlink transfer signal integrity:

"video signal input serial IC---> deserializer  video output, please provide the reliability test method of signal input to the output signal in the process, we will apply to the process of practical design, for each project design, reliability as the basis, first proposed scheme, then do the actual test support."

 

And they want to know the detail test project and test method.

    Miller,
    Please ask for your customer analysis the total high speed signal link design to improve the total link reliability test. The customer can learn more high speed design and test knowledge from TI's website (www.ti.com/.../fpd-link-serdes-support-training.page) or Keysight/TEK/Lecroy's website.
    To be simple, customer should assess the transmission channel s parameters, on-board high speed signal and clock signal's performance, and the output jitter generation, and input total jitter spec. to have enough margins to match SerDes link design. And the final product should pass the PVT test, which are some basic test requirements for product reliability.

    best regards,
    Steven
