Zubair,14bit/80MSPS is not available. For 80MSPS, you must use 12bit mode.Thanks,Chuck Smyth

HI Chuck,For normal OP-Amp, we know, there is -3db bandwidth. I am wondering if the VGA of the AFE5801 has the similary thing.

Junwei,Do you want diff in/diff out? Or single in/diff out? What is your BW concerns? Look into the THS4130 for fully-differential or the LMH6629 or LMe49990 for single-ended.Chuck Smyth

Chandu,If you are setting the bias current to zero to isolate the afe during transmit pulse you need to be aware that when you turn the bias current on it will inject a bump into the signal that will...

Chandu,The VCAT is the analog TGC, a DC or AC input will control the envelope of signal. If your question is why an attenuator instead of a gain stage, this is done because of better DC offset control...
