Hi all,

New comer here. I would like to get help as following question,

I've got the circuit for Digital part of the JVC EX-A3 mini system.
I found the the XTI pin of the DIF chip AK4112B just feed 3.3V as the master clock.
It makes me confuse why can just feed the 3.3V can make it?
I checked the datasheet already and there is no such example shown can be work like this!

Would guys show me how it works?
If I going to feed the external clock for the modification.
Should I just feed it from there? Thanks!
