FEATURES

I N T R O D U C T I O N

T he AD 73322 is a dual front-end processor for general

purpose applications including speech and telephony. It

features two 16-bit A/D conversion channel and two 16-bit D/

A conversion channel. Each channel provides 70 dB signal-

to-noise ratio over a voiceband signal bandwidth.

Up to 4 CODECS (2 Devices)Can Be Configured In

Cascade.

Interfaces To The ADSP-2181 EZ-KIT LITE.

Stand Alone Capabiliy.

T he AD73322 is suitable for a variety of applications in the

speech and telephony area including low bit rate, high quality

compression, speech enhancement, recognition and synthe-

sis. T he low group delay characteristic of the part makes it

suitable for single or multichannel active control applications.

Daughter Board for Quick Demo of CODECS

Various Link Options For Setting Configuration.

On Board +5V Regulator.

On Board Clock Generator.

T he gains of the A/D and D /A conversion channels are

programmable over 38dB and 21dB ranges respectively. An

on-chip reference voltage is included to allow single supply

operation. A serial port (SPORT ) allows easy interfacing of

single or cascaded devices to industry standard DSP engines.

On Board Anti-Aliasing.

E VAL-AD 73322E Z / E VAL-AD 73322E B

T he AD73322 Evaluation board can be supplied either

with or without an ADSP2181 EZ-KIT LIT E Board.

EVAL-AD 73322EZ contains an AD73322 evaluation board

and a modified EZ-KIT LIT E board. EVAL-AD 73322EB

contains an AD73322 evaluation board and the material

needed to modify a customers existing EZ-KIT LIT E

board.

T he AD73322 is available in both 28-lead SOIC and 44-lead

LQFP packages.

Full data on the AD73322 is available in the AD73322 data

sheet available from Analog Devices and should be consulted

in conjunction with this T echnical N ote when using the

Evaluation Board.

An existing EZ-KIT LIT E board can easily be modified to

interface with the EVAL-AD73322EB board by carrying out

the following modification:

Included on the evaluation board, along with the two AD73322

Codecs are a power supply circuit, a clock generator circuit,

a cascade selector circuit and a daughter board. T hese are

explained in detail on the next page.

- Solder the 40 pin right angle header (included in the EVAL-

AD 73322EB package) onto the EZ-KIT LIT E board in

position P3, pins 11-50, with the header pins facing the edge

of the board.
