S/PDIF Transceiver faulty??

[spresto9]

Hi All,
I have a s/pdif transceiver connected to my Cronus to convert to s/pdif
having caerfully studied the manual and data sheet for the 8804
and double checked the connections and switch settings (all as manual)
I have silence.
The only way to get any sound out of s/pdif is to set the Transceiver to slave (AIF/MS low) and connect MCK from Cronus to SCK on ransceiver, this results in extremely distorted music on s/pdif out.
All the led's stay the same no matter what the settings or connections.

My question is could this be a faulty clock on the board?

Cheers Steve

Sorry... the labels for AIFCONF0 and AIFCONF1 are reversed on these new boards. Try swapping those.

Hi Brian,
I have tried that, I have checked the settings directly at the chip pins to be sure the logic is correct.
Are the settings and conections in the transciver manual correct to connect to cronus
DCK - BCK
D1 - LRCK
D2 - DIN
GND - GND
Thanks Steve

Hi Brian

Quick update, these are the measured iogic voltages, the 42mv looks wrong to me any thoughts?



Thanks Steve
