DS90UB947-Q1: about jitter transfer function

Part Number: DS90UB947-Q1

Hello，

I have a question about the λSTXBW and δSTX, how to test them ? It should be tested with fixed pattern, but the FPD link pattern are random like the total output jitter test conditions, so I am not sure λSTXBW and δSTX test conditions, could you please help me to understand these two parameters? 

Best regards

Kailyn

    Hello Kailyn,

    This is not a parameter that the customer needs to characterize during their system design and it is for informative purposes anyways since the parameters are only given as typical values. We do not have a test procedure we can support providing to the customer for this parameter

    Best Regards,

    Casey
