Personal bickering and squabbles have no place here. OT posts have been removed.Thankyou, hopefully we can have an on-topic discussion now.
There are two main reasons I ask about the AD1893. Firstly, there is very little about in online, the datasheet is available of course, but there are very few mentions of it apart from that, not a single circuit schematic to be found, it just seems to be a very uncommon chip to see utilised, so information is very lacking.
Secondly, the primary application I could find was in TEAC's high end VRDS CD player, but most of the discussion around that application centres on removing the AD1893, such as this mention here:
TDAC1543 - Non oversampling DIY DAC

Why don't you look at the link you provided. It has the full schematic of the VRDS-25X including the AD1893.
Here's some better quality pics of the board:
As there is such a paucity of info on the AD1893, I looked at what was available on the other Analog Devices SRC ICs such as the AD1890/1 and AD1896, they are similar but different.
I did find some information that is quite helpful in an Analog Devices application note:
Another app note about designing a DAC gives some details of how to implement the AD1890/1 and should also be applicable to the AD1893:

Hi! You will not find a service manual for the CP 500. Probably they are not on the Internet, I myself have been looking for it for a long time, Dolby apparently does not distribute it, and very few engineers have such instructions.
As a result, I quit looking and try to figure out this board myself
