TDA2705(P):
1 WSAB Word select I2S input
2 CLAB Clock I2S input
3 DAAB Data I2S input
4 EFAB Error flag
5 FS44 Sampling frequency input
6 SCAB Subcode clock
7 SDAB Subcode data
8 Vss Ground
9 XIN Crystal oscillator input
10 XOUT Crystal oscillator output
11 XSYS System clock output
12 TESTB Test input
13 DOBM Digital audio output
14 DOEN Digital output enable
15 ATSB Attenuation
16 Vdd Power supply +5V

PCM 2705 is used in Grundig:
CD2
CD3
CLCD6

PCM 3522 is used in Philips:
CD624
CD824
CD850II
CD930
CD931
CD940
CD951
...
Again, that's all I have.

Hi

I have been looking for these a long time

There are no datasheets (anymore). I even contacted Philips Semiconductors (internally, I work at Philips).

I have some typical application scheme's, these may help together with the pinout given below.

I think the 2705 equals the 3523.

They are used in Marantz 10, for example. Also CDM12 uses it.

It generates SPDIF from I2S, often used together wioth SAA7310

A Crystal CS8402 can do the same, if I am right

best regards

I want your typical application scheme's

Re: I want your typical application scheme's

Hello

Send me a mail (offline) with your address, I can send a hardcopy, or eventually scan the relevant parts of the Marantz circuit

regards

Hi

Sent a JPG, about 500k

anyone else interested ?

Hello

I have received the schematic.Do you have all schematics of that.I need the PHILIPS CD schematic just yet.

Hi

This is all I have, it is just a typical example

PCF2705 has been used many times tohether with SAA7310. I think all the circuits are the same

What exactly is the problem with your DC player and which type do you have ?

 

[mdlover]

don't know if this diagram is useful?

Thanks Mdlover

Hi MDLover

This looks like you have a scan taken from a spec, do you have any more info from that same spec ?

Would love to receive a copy

all the best

Hi Guido,

The pic was scanned from an article on "Elektor Electronics" published 1992.

The article was about modifying an Philips CD player (adding SPDIF digital output). That's all I have about this chip.

Cheers

OK, clear enough

I even may have that article.....

on a wide range of PCM decoders the internal parts of PCF2705P and PCF3523P to form a S/P-DIF (DOBM) protocol for an external digital output socket are integrated.
If in cd players are PCM decoders in use without this integrated logic parts (like SAA7310/SAA7210 e. g.), and a digital output was wanted, the above mentioned parts then additional necessary.
Philips CD608/618, Grundig CD35 and various other uses this S/P-DIF transmitter parts.
But I don't understand, why no detailed datasheets from Philips Components/NXP was published until now.
