DS90UB953-Q1: The VSWR request for cable

Part Number: DS90UB953-Q1

Hi,

Here are some question:

1. Is there any data about VSWR requirement for FDPLink cable?

2. The highest data rate is 4.16GHz, so the BW of cable we need is 4.16GHz/2=2.08GHz?

Thank you.

  • Hello Chentsu,

    1. We recommend the return loss (S11) to be better than -10dB. So the VSWR should be better than 1.92.

    2. Yes, the BW of cable should be above the Nyquist frequency or 4.16Gbps/2.

    Best regards,

    Cera
