EVALUATION BOARD
Burr-Brown’s DEM-PCM1710 evaluation board for the
PCM1710 is capable of evalution of the PCM1715 and
PCM1710. Digital input signals for the evaluation board are
LRCK, BCK, DATA, and system clock (256fs or 384fs).
Power supply requirement is only +5V.
The DEM-PCM1710 has a pattern layout for an optional
crystal oscillator. However, the crystal is not installed.
