I2S on a Marantz CD4000

[haik]

I have a CD4000 made by Marantz. I installed the mini 2496 kit for better audio. This kit has a AK4396 DAC.

The CD4000 has S/PDIF out (and is now used by the kit). But I see in the schematics of the CD player 3 lines:

CLOCK
WORD SELECT
DATA.

they go into the (original TDA 1545A DAC).


Can these line be used to go into the AK4396 directly? As so not to use the CS8416?
In the schematics of the kit, I see 4 lines, which might be used for that:

BICK (audio serial data clock)
SDATA (audio serial data input)
LRCK (Left / Right clock)
MCLK (master clock)


If these are the same, what "mapping" is used?

I assume DATA -->SDATA.

What to do with CLOCK and WORD SELECT?

Or is not so easy.... and some conversion is needed?
