GENERAL DESCRIPTION
The AD73322 is a dual front-end processor for general-purpose
applications including speech and telephony. It features two
16-bit A/D conversion channels and two 16-bit D/A conversion
channels. Each channel provides 77 dB signal-to-noise ratio
over a voiceband signal bandwidth. It also features an input-to-
output gain network in both the analog and digital domains.
This is featured on both codecs and can be used for impedance
matching or scaling when interfacing to Subscriber Line Inter-
face Circuits (SLICs).
The AD73322 is particularly suitable for a variety of applica-
tions in the speech and telephony area, including low bit rate,
high quality compression, speech enhancement, recognition, and
synthesis. The low group delay characteristic of the part makes
it suitable for single or multichannel active control applications.
The A/D and D/A conversion channels feature programmable
input/output gains with ranges of 38 dB and 21 dB respectively.
An on-chip reference voltage is included to allow single-supply
operation. This reference is programmable to accommodate
either 3 V or 5 V operation.
The sampling rate of the codecs is programmable with four
separate settings, offering 64 kHz, 32 kHz, 16 kHz and 8 kHz
sampling rates (from a master clock of 16.384 MHz).
A serial port (SPORT) allows easy interfacing of single or cas-
caded devices to industry standard DSP engines. The SPORT
transfer rate is programmable to allow interfacing to both fast
and slow DSP engines.
The AD73322 is available in 28-lead SOIC and 44-lead LQFP
packages.
