Does anyone know what the crystal frequency of the the CD5400?

The service manual says something about a 8Mhz and a 8.467 Mhz crystal, but looking at the datasheet of the DAC, that can't be correct...

16.9344MHz. But a new clock doesn't want to go in in place of the existing crystal, it needs to go in after the rather nasty PLL and digital synthesiser that allows pitch control. I'll be fitting one of Guido Tent's clocks to mine and I'll post details once done.

Ah, thanks but why doesn't it say anything about that in the service manual.. Strange stuff.

I was also wondering about the BU thing. It would make sence that it is used for the pich control. I don't care about it. If would lose it, I won't miss it. it would be great to get the details!

The service manual was precisely where I got the crystal frequency information from. I really ought to have opened up the player and measured the frequency going into the DAC chip...

I found my manual with google, so it should not be to hard to find a working one...

@EC8010: then you must have a different one, since mine does not contain that number (nor part of it).

Right, that's it! The lid's coming off and I'll make a measurement.

I've just had the lid off. X601 is an 8.4672MHz crystal and that's also what it says on the parts list of the manual, I wondered how I'd got it wrong, so I went back to the diagram...

Thank you, Philips. Let's make things better, huh?

Yes, that's what I also saw, but how does this go together with the frequencies speficied the the DAC datasheet (3.5 System Clocking)?

I'm not annoyed at Philips, no, really, I'm not, not at all...

I'll have the board out and probe the DAC pin. Then, when I've carefully done that, I'll go and find some bubblewrap to jump up and down on and scream.
