Can I run TDM16 at 96kHz?

I have done a few designs using ADAU1446 and ADAU1442 in which we run the chip from a 24.576 MHz crystal so I have done TDM8 interfaces at 96kHz without problems.

Now I see from the data sheet that ADAU1450/51/52 claims "48 channel, 32-bit digital I/O up to 192 kHz" but only has 4 SDATA input pins and 4 output pins, but SDATA0 and 1 can run TDM16

My question is, can theses interfaces run TDM16 at 96kHz or even 192 kHz and if so what frequency master clock do we have to provide and how do we provide it? Is it the chips own master clock or do we supply an external clock?

 

thanks
