4.4.1 Synchronization of Multiple Devices
Master and Slave Operation
CS5364 operation depends on two clocks that are synchronously derived from MCLK: SCLK and LRCK/FS.
See
The CS5364 can operate as either clock master or clock slave with respect to SCLK and LRCK/FS. In Mas-
ter Mode, the CS5364 derives SCLK and LRCK/FS synchronously from MCLK and outputs the derived
clocks on the SCLK pin (pin 25) and the LRCK/FS pin (pin 24), respectively. In Slave Mode, the SCLK and
LRCK/FS are inputs, and the input signals must be synchronously derived from MCLK by a separate device
such as another CS5364 or a microcontroller.
both Master and Slave Modes.
The Master/Slave operation is controlled through the settings of M1 and M0 pins in Stand-Alone Mode or
by the M[1] and M[0] bits in the Global Mode Control Register in Control Port Mode. See

To ensure synchronous sampling in applications where multiple ADCs are used, the MCLK and LRCK must
be the same for all CS5364 devices in the system. If only one master clock source is needed, one solution
is to place one CS5364 in Master Mode, and slave all of the other devices to the one master, as illustrated
in
external source and time the CS5364 reset de-assertion with the falling edge of MCLK. This will ensure that
all converters begin sampling on the same clock edge.
