Serial Data Port Master Clock Modes
Either of the AD1896 serial ports can be configured as a master
serial data port. However, only one serial port can be a master
while the other has to be a slave. In master mode, the AD1896
requires a 256
fS, 512 fS, or 768 fS master clock (MCLK_I).
For a maximum master clock frequency of 30 MHz, the maxi-
mum sample rate is limited to 96 kHz. In slave mode, sample
rates up to 192 kHz can be handled.
When either of the serial ports is operated in master mode, the
master clock is divided down to derive the associated left/
right subframe clock (LRCLK) and serial bit clock (SCLK).
The master clock frequency can be selected for 256, 512, or 768
times the input or output sample rate. Both the input and out-
put serial ports will support master mode LRCLK and SCLK
generation for all serial modes, left justified, I
2S, right justified, and
TDM for the output serial port.
