Dear sir:
I found there's abnormal output issue when input and clock signals are off. Here's 3 pictures I got from power up, data in and data off of the TXout0+
Power up step picture, TXout0+ is correct with no clock/ data input
signal (Txout0+) on with clock input picture which is correct waveform
signal (Txout0+) with clock/ data input off picture, there's unknown signal output even without clock/ data inputs.
I have also checked the Txclkout+ and all other LVDS pairs and got similar unknown waveforms as well. Are these waveforms reasonable?
Why we have these waves after parallel clock/ data inputs?
Thank you!
Brian
