Hello Rodrigo-san,
Here is my comments below
What is the specific data rate and test pattern being used by customer when issue is observed?
As noted above, based on our test, we observed exact the same symptom with customer using PRBS-7 pattern at 3…
Hi,
Thanks for the reply, I don't have DS110DF410EVM , and I am still confuse about the situation why the ds110rt410 can't lock to input signal automatically,here are my schematic. retimer.pdf
Part Number: DS110DF410 Hi TI,
I've been testing the DS110DF410 on my test card. This is 12 DS110DF410 transmitting 48 channels of PRBS31 data at 10.5 GHz. These channels are being output onto short tracks to an optical transciever and received by an…

Other Parts Discussed in Thread: DS110DF410EVM The source code to the DS110DF410EVM Atmel part would be nice to look at. I just don't want to start from scratch.
Thanks in advance!
Hi Kawai-san,
The bit transition point should appear at the same point if the same board is used at the same data rate. Changing data rates result in a different time where the bit transition is caught after the delay. For example, compare the eye at…
