Tried to use cd-rom drive plus a NOS 1543 dac to bulid cd player. The controller + cd-rom drive works find when use analog output. But when connect the SP/DIF to this 1543 dac

the controller freeze with message "Looking for IDE". Disconnect the dac, the cd-rom driver plays normally. Any idea what's wrong?

I don't have other dac to try.
I did further test on the dac with a dvd player's coax out. It didn't work also. From the link, it works with the author. And I also saw some similar schematic (same 75R at input, using 8412 or 8414 with 1543, different output RC network) DAC on other web sites and the authors also have success. I've check my connection over and over again and didn't spot anything wrong. What is the most likely area where I made msitake? What would you check first if you are in such situation? Please help.

compare with my DAC circuits, just one pin different in CS8412, pin16 should be connect to ground.

Where are you buy TDA1543 from Hong Kong?
and
How much?
jojo,
the controller is from here http://www.cdream5.com/htm/CDCV30_01.htm
MCLL,
Thanks for the schematic. What is the 10-pin IC before the output?
My 1543 was from here www.futurlec.com, not from HK.

Not 10-pin IC...
Should be output Single Op Amp like AD797, OPA604 and etc.
How much include delivery charge?
