Default Conversion from I2S and similar to DOBM - S/P-DIF Transmitter IC's: Overview wanted

It is easy to find a wide range of SPDIF receiver ICs (digital audio interfaces) for DA converter IC's. Cirrus Logic (CS8412-CS8416-CS8420), Yamaha's YM3623 and NXP's TDA1315 are examples.

But for the opposite function (i. e. SPDIF transmitter IC's) I have difficulties to get an overview.
The reason therefore is, each manufacturer has its own term therefor. NXP/Philips call this kind of ICs "ADOC" (Audio Digital output circuit) and Cirrus calls it "Interface Transmitter".

I have found only the follow (Datasheets not available by NXP):
PCF2705P (NXP)
PCF3523P (NXP)

Help me I need MAB8441 PCF3523 PCF2705 DataSheets
PCF3523P and PCF2705P - differences?
Pcf 2705
Digital transformer
PCF2705P Data Sheet

In the attachement the internal simplified schematic of the PCF3523P. In the service manual of the CD-15 from Marantz there is to find the simplified schematic of the PCF2705P.

Who knows currently available types with support of various input formats except only I2S ??
Thank you for your advices.

Widen your gaze to transceivers and you'll many more. TI also makes a pair of transmitters, the DIT4096 and DIT4192.
