DEM-PCM1800 BASIC CONNECTIONS

AND OPERATION

• Power supply can be provided at +VCC, GND connector

CN1.

• Audio analog inputs are VINL, VINR connector CN2.

• Digital ground return to digital interface source should be

connected at GND, connector CN3.

• System clock (either of 256fS

or 384fS

or 512fS

) should be

provided at SCLK, connector CN3.

• Operation Mode (master mode or slave mode) and selection of system clock can be controlled by switch MODE

0, MODE 1.

• The high pass filter function can be controlled by the

switch bypass.

• Audio data format can be controlled by switch FMT0,

FMT1.

• To enable the reset function push RESET (switch SW2).

Master Mode Operation

• LRCK, BCK, DATA, are outputs for PCM Audio data.

• LRCK, BCK, DATA, outputs are located at connector

CN3.

Slave Mode Operation

• LRCK, BCK, DATA, are inputs for PCM Audio data.

Synchronized timing between LRCK (fS

) and system

clock (256fS

, 384fS

, 512fS

) is required.

• LRCK, BCK, DATA, inputs are located at connector CN3

and are selected by setting FSYNC = H connecting JP2.
