YM3414 digital filter: data needed

Hello,

One of my current projects is converting a CD-player DAC to receive S/PDIF
signals.
Data has to be fed first into a YM3414 digital filter, which differs
slightly from the YM3433,
on which info can be found on the internet.

Does anyone know where to find the data*** of the YM3414 itself?

Thanks in advance,

DJ
