ADAU1452 how to split CLKOUT signal
Hi,
I have a quick question. I want to connect 3 x DACs (PCM1798 from TI) to the DSP and was wondering, how can I split the Master Clock signal (from pin 23) to connect to all 3 DACs? I've noticed that ADAU1452 has 4 different CLKOUT settings (Lowest to Highest - from 2 to 15 mA @ IOVDD = 3.3V), so can I just use a single line to connect all 3 DACs in parallel? Do I need termination resistors to split the signal? If yes, then what resistance/CLKOUT level combination would work best?
Thank you.

I used one of these https://www.mouser.com/ProductDetail/863-NB3N551DG, with 33 ohm resistors close to the clock outputs of the chip to eliminate signal reflection, though you are probably okay without it.
