[FAQ] DS90UB960-Q1: BIST Duration

Part Number: DS90UB960-Q1

Hi Team,

What is the recommended duration to run the BIST?



  • Reed,

    I would recommend to set this based on your desired BER confidence level and the desired BER level you are targeting for your application. You can use a basic calculator like this to find the time: 

    The typical BER confidence level most designers use is >95%

    For example if you test for 10 seconds you could have 98% confidence level of 1e-10 BER:

    If you want >95% confidence level of 1e-12 BER then you would need to run for ~15mins:

    Best Regards,
