Part Number: DS280DF810

1. DS280DF810ABV is used on our schematic. Do we need to add external AC coupling caps on RX of DS280DF810ABV?

2. For DS280DF810ABV, is there no internal AC coupling caps both on Tx and Rx?

3. For DS280DF810ABW, is there internal AC coupling caps both on Tx and Rx?

Thanks,

Jimmy Huang

Hi Jimmy,

DS280DF810 has AC coupling Caps on both inputs and outputs. Therefor you do not need to add these on both inputs and outputs of the device. Options you have listed mainly refers to the number of parts per package when these are ordered.
