Part Number: DS280BR810
Other Parts Discussed in Thread: DS280BR820

Hi Team,

Could you advise me on a questions bellows:

Q1. The minimum data rate, DS280BR810 can handle.

      The DS280BR810 datasheet insists that it supports as high as 28Gbps.

      However, I cannot find the information on the lowest corner of the data rate.

Q2. Can you share with me an information on the AC transfer function curve of this device on the minimum EQ and DE.

      I want to check the lowest corner of frequency bandwidth.


Best regards.
Yusuke

    Greetings Yasuke,

    DS280BR820 has integrated 220nF AC coupling Cap. We should be mindful of the RC time constant, data pattern run length coding, and data rate. As long as we are within this time constant we should be fine. Also, note at lower data rate, BR820 does not have much gain. Please recommend your customer to use IBIS-AMI model of the DS280BR820 to do system analyses.
