The AK4387 must be reset once upon power-up.
10µF electrolytic cap.
An external TTL clock should be input on this pin.
When at “L”, the AK4387 is in the power-down mode and is held in reset.
Normally connected to VSS with a 0.1µF ceramic capacitor in parallel with a
No internal bonding. This pin should be opened or connected to VSS.
