SPDif and PCM67 ??

Tekko · 22nd January 2006, 08:16 PM

I want to make a dac with Toslink input and i have a PCM67 but unfortunately it needs separate data for L and R as well as clock signals, connected to it theres a filter ic that splits a digital signal down to these L/R signals, nut still theres these clock signals input. Whatr do i need to make this a SPDif dac ?

An understanding of the datasheet, a SPDIF receiver and a digital filter.

The digital filter is in place, OKI M6528-01, a ic i cannot find a datasheet on.

Where can i find a spdif receiver ? I dont wanna buy one.

Is this a cd player or something else? OKI digital filters are new to me.

That might be a problem.

Its what remains of the cdp from a sony all in one.

Model No.? You are going to have to get a SPDIF rx from somewhere or your project is dead before it starts.

I dont remember the model, it was the kind with cd in the bottom, dual tape deck above and radio at the top.

A large main board alog the right side and two boards behind the front.

It was 2x25w with a stk module s poweramp that was a separate amp unit mounted in the bottom.

What other chips are present? A picture?

The ics are, on the cd drive: CXA1372AQ. On the board: CXD2500BQ, M6538-01 and PCM67.

The M6538-01 is most likely a microcontroller. Follow the tracks connected to CXD2500BQ pins 71,72 & 74 to see where they go and do the same with pin 32 of the same chip.
