DCX2496 mod for Digital OUT x 3

[noah katz]

"In case anyone didn't know, they had to re-design the circuit due to some IC no longer available....."

So there are no other additional features or functional enhancements?

Thanks

mm2,
When I get the new unit, I'll open it and see what has changed.
I have two of the 'old' DCX in the car (one left channel, one right channel)
so will be able to do good comparison testing of the new units

I made SPDIF transmitter board for DCX2496.
It is easy and you can get 3Way digital X-over device at very cheep price.

(1) The signal you need
from AK4393, get these signal with very slender cable, solder with microscope or something.
Pin 3:MCLK?APin 5:BICK?APin 7:LRCK
These signals are common for all AK4393.

Pin 6:SDATA , on the side of AK4393, you can find 10ohm R,
you can get 3 SDATAs from this register's solder easily.

(2)CS8404 configure
PRO=Low, TRNP=Low, M2M1M0=100, I2S mode.
Pullup RST with 10kohm.

(3)CS8404 connection
?@MCLK->MCK, BICK->SCK, LRCK->FSYNC, SDATA->SDATA

(4)SPDIF output is done by TOTX173

(5)5V power is made by 7505, on each CS8404, 9V is supplied from Pin 1 of 7805 on the main PCB. GND is supplied from Capaciter's solder. (maybe direct from power module is better)

Then now you can get 3 SPDIF signal, for DCX2496's ch12, 34, 56.
Do not forget to make DCX2496's configuration to LL-MM-HH.?@

Now I'm using this for connection to 3 units Panasonic SA-XR50(maybe same as SA-XR45 or so).
