    Hi Toshi,

    Can you provide some more details for your question? PLL unlock time is not a typical parameter, please define the conditions you have in mind.

    Are you asking about power down time?

    Hi Mike-san,
    Thanks for your response.
    I'm sorry the insufficient description.
    My questions are;

    Q1: How much is the detection time of SER PLL UNLOCK after SER CLKIN lost?
    Q2: How much is the detection time of DES PLL UNLOCK after lost of C0/C1 in a stream ?

    Regards,
    Toshi

    Hi Toshi,

     

    I do not have an answer for question 1. The serializer does not have a lock status pin so this is a difficult parameter to measure or specify.

    For question 2, the deseriliazer will lose lock after the loss of one complete serial symbol. For these devices one serial symbol is 28 bits (28UI) long.
