Hello, two LTC6829 are capacitively coupled, the cable length between the 6820 is ~2 Feet. The capacitor is located in the destination PCBA
1. The resultant IP-IM waveform includes a tail, which results in not meeting the 1/2PW(D) spec of 60ns. It's unclear what the ramifications are, but functional it appears to work.
A. What are the ramifications if the timing spec is not met ?
B. If there was a problem, how would it manifest?
2. The IP and IM are pulled up with 3K R, changing the pull up to ~500R helps. How much current can the IP/IM sink
