Serial Data Port Master Clock Modes
Either of the AD1895 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 AD1895
requires a 256

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

and TDM for the output serial port.

Bypass Mode
When the BYPASS pin is asserted high, the input data bypasses
the sample rate converter and is sent directly to the serial output
port. Dithering of the output data when the word length is set
to less than 24 bits is disabled. This mode is ideal when the
input and output sample rates are the same and LRCLK_I and
LRCLK_O are synchronous with respect to each other. This
mode can also be used for passing through non-AUDIO data
since no processing is performed on the input data in this mode.
