The AK4103AVF seems to be discontinued and out of stock. Will you update the project to other IC options like WM8804G?

Hi, I was wondering if this could be used also with a Sound Canvas SC-55.

In particularly, which input points shall be used for sysclk, data, qclk, wclk and reset?

Thanks in advance!

I'm trying to adapt the design to SC88VL (a small version of the SC88 with the size of a SC55). The service manual is available.

Getting DATA, WCLK and SYSCLK(?) is convenient, as there are unused solderpoints on the mainboard as outlined by the japanese project you already link to (C32-C34).

Getting QCLK(?) and RESET will be more effort, those are not needed for TC9231N but are needed for AK4103 (the lower part is IC36)

I'm not completely sure if I may be mixing up QCLK and SYSCLK. On your main page you write "CLK=MQCLK". But on your annotations for SC88 pro, CK = QCLK. In SC88VL, there is a CK pin as well on IC36, meaning the BCLK, which Roland also names CLK, is probaby SYSCLK. Can you help me verifying signals?

Access to CK may be possible at R80/C98 right next to IC36.

For RESET multiple options are available - maybe IC1 directly at the heat sink.
