Hi,
Looking for anyone with some experience of the SN75DP130 output jitter when subjected to high input jitter...
We have a very simple design of DisplayPort repeater card using the SN75DP130 device. We see around 90ps (at 5.6Gbps) at the input to our card and around 120ps at the output. This looks really bad compared to the data sheet, which seems to imply much lower figures for output jitter. We don't have a simple means to change EQ, we are set to default automatic low levels, which is too low for this level of input jitter according to the datasheet, but we want to try and determine if this is the only problem or there is something else fundamentally wrong with our design / PCB layout.
So input from anyone with experience of the 'DP130 and jitter would be really appreciated.
Thanks
Julian
