2. SYSTEM CLOCKS AND DATA
The CDB4265 implements comprehensive clock and data routing capabilities. Configuration of the clock and data
routing can be easily achieved using the controls within the Board Controls group box on the CDB4265 Controls tab
in the GUI software application.

Clock Routing
The master clock signal (MCLK) may be sourced from the canned oscillator (Y1), the CS8416 S/PDIF re-
ceiver, or the PCM I/O header (J15)
The sub-clock signals (SCLK and LRCK) may be sourced from the CS4265 in master mode, the CS8416 in
master mode, or the PCM I/O header.
Clock routing configuration is achieved using the MCLK Source and Subclock Source controls within the
Board Controls group box on the CDB4265 Controls tab in the GUI software application.
Data Routing
The CDB4265 implements comprehensive data routing capabilities. The SDIN source of the CS4265 may
be easily selected using the provided GUI software application.
2.2.1
The CS8416 S/PDIF receiver, the PCM I/O header (J15), or the CS4265 serial data output (SDOUT) may
source the serial data input of the CS4265. Configuration of the CS4265 SDIN1 and SDIN2 source is
achieved using the respective CS4265 SDIN Source control within the Board Controls group box on the
CDB4265 Controls tab in the GUI software application.
2.2.2
The CS8416 S/PDIF receiver, the PCM I/O header (J15), or the CS4265 serial data output (SDOUT) may
source the serial data input of the CS4265. Configuration of the CS4265 TXSDIN source is achieved using
the CS4265 TxSDIN Source control within the S/PDIF Transmitter group box on the CDB4265 Controls tab
in the GUI software application.
