Product specification
Digital telephone answering machine chip
PCD6003
The analog and digital parts of both CODECs can be
independently activated by the SYMOD register; see
Section 9.2.2. Bit 4 of SYMOD is used to activate the
microphone supply voltage, if the bit is logic 0 the supply is
off.
The balanced microphone input has a minimum differential
input resistance of RMICDM, and the balanced line interface
input has a minimum differential input resistance of
RLIFINDM.
The output resistance of the balanced CODEC outputs is
RLIFOUT for CODEC1 and RSPKR for CODEC2 at a
differential output level of 1350 mV (RMS). For exact
measurement conditions and specified values see
Section 17.5.
