Hi Dusan,

IOVDD needs to be connected to a voltage supply - either 1.8V or 3.3V.

SCL and SDA should be pulled up to this IOVDD supply.

Since the devices share a TDM bus, ensure they are assigned to different output channel slots, and each is configured to transmit Hi-Z on unused cycles.

Best,

Garret
