remove saa7030 - Page 2

rfbrw · 8th June 2005, 09:07 PM

Yes, I would remove it completely.

pisky · 8th June 2005, 09:13 PM

Do you think the connection that I have explain before can be correct?

rfbrw · 8th June 2005, 10:16 PM

Yes it will work but if you have pins 13 and 15 of the SAA7000 connected to the TDA1540P at the same time as pins 3 and 10 of the SAA7030 you will have problems.

Ok, thank you for your advise

As soon is possible I will try these modification

Hi rfbrw

You indicated that it is easier to connect a TDA1541 to the SAA7000, could you please elaborate how one would do this. I have a Philips CD 202 and would like to try this mod.

Cheers

The pin on TDA1541a are:
PIN1 (latch enable input/ word select input),
PIN2 (bit clock input)
PIN3 (data left channel input/ data input (selected format))
PIN4 (data right channel input)

On SAA7000
You must put PIN16 to +5V for enable 16 bit output
Pin 16 connect to PIN2 of TDA1541 (but I'm not sure)
PIN15 to PIN4 of TDA1541
PIN13 to PIN3 of TDA1541
and I think PIN 12 to PIN1 of dac

rfbrw can help you better.........

Ciao

SAA7000 ---> TDA1541A
DLCF 13 ---> DATA_L 3
DRCF 15 ---> DATA_R 4
CLCF 14 ---> BCK 2
STR1 12 ---> LE 1

Pin 27, OB/TWC, must be connected to -5v placing the TDA1541A in simultaneous L and R data mode.

Leave Pin 16 on the SAA7000 connected to ground. The SAA7000 is already set for 16 bit data as the SAA7030 expects 16bit data.

Hi Andrea and rfbrw

Thank you both very much for your feedback. I'm still a novice when it comes to electronics and have ne more query;

if I'm taking the 16 bita data from the SAA7000 directly to the TDA1541, should I remove the SAA7030.

I plan on building the TNT 1541 dac (without 8412) to use after the Saa7000, when its all implemented I'll report back with my findings.

Cheers

Richard

I did. For reasons of convenience. The empty holes provided easy access to the SAA7000. I also connected the inputs of the TDA1540's to ground.

Hi rfbrw,

are you using a SAA7000 with TDA1541A? Which cd-player?

Ciao
Andrea
