description
The voice-band audio processor (VBAP) is
designed to perform transmit encoding analog/
digital (A/D) conversion, receive decoding
digital/analog (D/A) conversion, and transmit and
receive filtering for voice-band communications
systems. The device operates in either the 15-bit
linear or 8-bit companded
(碌-law
or A-Law) mode,
which is selectable through the I
2
C interface. The
VBAP generates its own internal clocks from a
2.048-MHz master clock input.
