I am using a 2412 on my product. for testing purposes i would like to send my product non synchronous data using a 2411. My board does not require a processor so I want to drive the clock of the 2411 with a 10MHz clock My understanding is that this configuration should work because the 2411 is just capturing the state of the input pins ever clock period. I can see that the 2411 is powered up, the clock is running and that the Rout+/- pins are being driven.
However when I plug my device into the test apparatus, the 2412 on my device does not decode the data from the 2411. I know that the issue is not with my device under test as the onboard 2412 functions well with it's mating product which contains a 2411.
My set up is as follows:
VDDIO = 3.3V; VDDTX = VDDHS = 1.8V
VDDSEL = 1; RFB = Config1 = Config2 = BISTEN = 0
De-emph = Floating
Is there anything that i am doing incorrectly? Could the problem be with my clock source?
