• If the input is set to master, Fsi ≤ XTI/128 and Fso ≤ XTI/130.
• If the output is set to master, Fso ≤ XTI/128 and Fsi ≤ XTI/130.
• If both input and output are set to slave, XTI ≥ 130*[maximum(Fsi,Fso)], XTI/Fsi < 3750, and XTI/Fso <
Clocking
In order to ensure proper operation of the CS8421, the clock or crystal attached to XTI must simultaneous-
ly satisfy the requirements of LRCK for both the input and output as follows:
3750.
