Other Parts Discussed in Thread: DIR9001
I am inputting TOSLINK to TORX1355(F) to the DIR9001. On occasion during power up the ERROR pin asserts high, AUDIO# asserts low, and no data is transmitted on DOUT. By reading the DIR9001 documentation it would appear the PLL cannot lock on the input signal.
I say on occasion, but in reality I have only been able to get data on the output a couple times using the same TOSLINK transmitter.
Do you know why this could be the case? I have attached the relating schematics below.
