Configuration jumpers – If jumpers are installed, the board is USB powered. If
jumpers are open then you must provide external stabilized power supply to pin9
and pin10.
Our recommendation is to use external power supply (pin9 and pin10) for
better sound quality.
Analog outputs are 2.8Vpp (5V power supply).

Configuration from PCM to DSD data format and back, is done by PIC1823 microcontroller, which 0.5sec after his work is done, is putted on sleep mode not to insert disturbances.
- Page 3 Recommended minimum requirement schemes of external power supplies External power supply for AK4396 and generators and reclocks on I2SoverUSB board. External power supply for USB part. If the two boards are powered from USB bus and the voltage from the USB host drops below 4.8V, 352.8kHz, 384kHz and DSD128 might not work (allowable minimum power supply for AK4396 is 4.8V).
