PCM2900C daisy chaining the clock.

Hi,

I want to use four PCM2900C codecs on one board. Is it possible to daisychain the osc clock in and out of the codecs ? First codec using a crystal and the other three XTO to XTI ?

I do not recommend daisy-chaining like that. What you may do is use one CMOS oscillator (not a crystal) and hook up multiple PCM2900Cs XTI in parallel (leave XTO open).

Ok, thanks for the quick reply. I will check the cost advantage and the space saving of this option
