DP83TC811R-Q1: 2 Quick questions

[FAE] Andrew Wang
Genius 10685 points
Part Number: DP83TC811R-Q1
Other Parts Discussed in Thread: DP83TC811S-Q1, AM3352

Hi Team,

1. Can DP83TC811S-Q1 directly connected with AM3352 through RMII interface?

2. DP83TC811S-Q1 pins: TRD_P/TRD_N goes through CMC (common mode choke) to connector, any isolation is needed in between?

Thanks!

Andrew

    Hi Andrew,

    DP83TC811S does support RMII operation. We have not tested it specifically with AM3352 but RMII is a standard interface. We test that DP83TC811S meets RMII standard so interfacing with AM3352 should not be an issue.

    The isolation requirement is as per 100Base-T1 standard and capacitors are need on TRD_P/N pins. You can use the datasheet and EVM schematics for reference.
