DESCRIPTION
DEM-PCM1800 is an evaluation board for the
PCM1800 20-bit stereo audio analog-to-digital con-
verter. The board contains a 24-pin SSOP IC socket,
mode control switch, and some bypass capacitors.
DEM-PCM1800 can be operated by connecting only a
power supply and system clock (either of 256f
S
or
384f
S
or 512f
S
). There are two kinds of operation
modes: Master Mode, and Slave Mode for operation
of the PCM1800.
In Master Mode, LRCK, BCK, FSYNC, and DATA,
are outputs. In Slave Mode, DEM-PCM1800 requires
LRCK, BCK, FSYNC inputs, and outputs DATA.
