Dear support team,

 

We want to know specification of CLKIN for ADAU1442 and ADAU1452.

 

We will use 12.288MHz clock source for CLKIN.(not crystal)

 

Q1: Is Input level of CLKIN same as digital input specification?

 

Q2:Can CLKIN receive a clipped-sine wave?

 

Q3:What is accuracy of frequency(ppm) needed?

 

Best regards,

Takepiro
