Other Parts Discussed in Thread: DS92LX2122
Hello,
We have a customer with below concern:
I have a DS92LX2121/DS92LX2122 hooked up in camera mode and I cannot get the system to reliably work. The camera PCLK is 27MHz. The normal failure mode is that I see a good PCLK at the deserializer with all data signals low.
I've done this:
1.) I take the serializer out of sleep mode after power on.
2.) Verified that the serializer has the proper inputs. The inputs include PCLK and video data.
3.) Ran BIST at 25MHz and verified no errors by looking at the PASS output.
On one of my deserializer CCAs I discovered that rapidly turning the power off and back on after power-up makes everything work ok. Of course this isn't a permanent solution but might help in tracking down the problem.
Please help me figure out what's wrong.
Appreciate your help. Roland
