FEATURES

PRODUCT OVERVIEW

The MX93000 Special Codec integrates key functions

of the analog-front-end of Digital Answering Machine

(DAM) into a single integrated circuit. The MX93000 is

intended to provide a complete, low cost, and single

chip solution for telephone applications requiring a

single +5V power supply.

• Single +5V power supply

• Sigma-Delta A/D D/A with digital filters

• Support u/A Law and 16-bit linear format

• On-chip automatic level control

• On-chip differential line driver

• On-chip digital volume control

• Programmable transmit/receive gain control

• Support switch paths for DAM (Digital Answering

Machine) applications

• Easy interface to general purpose DSPs

• Easy read/write of control register by microproces-

sors

• Programmable power-down

• Support power-low/battery-low detection

• 28-pin DIP/SOP package

The MX93000 Special Codec is especially powerful

when applied to some DAM models which are intended

to meet different countries' specifications in the same

system hardware. User can achieve this goal by

simply setting control firmware. This benifit will help

DAM system makers to save developing time and R/D

resources.

The A/D D/A converters are implemented with 2nd-

order sigma-Delta modulators. The on-chip digital

filters, which are carried out with 16-bit and 2's

complement format, are used to get the required

frequency response of a PCM Codec. The Codec can

support 8-bit u/A law and linear format. For the latter,

it is 16-bit format with 14-bit resolution .

PIN CONFIGURATION

28PIN SOP/DIP

Before the A/D digitizing the voice-band analog signal

into digital format, the analog signal can be processed

by a built-in Automatic Level Control (ALC) and pro-

grammable Gain Amplifier (PGA). The ALC circuit

controls the input level of A/D converter to about 1.5

Volt, so as to get a better signal to noise ratio during a

low-level input. The PGA circuit is used to control the

gain of different sources : microphone, aux or line

input.

After the digital data is converted into analog signal by

the D/A converter, a fully differential line driver is

supported to drive the telephone line directly without

the need of external amplifier. On the other hand, the

analog signal can be monitored by passing the analog

signal to the on-chip volume control circuit, which can

drive an external driver like LM386.

In addition, the MX93000 supports switches and

control registers so that users can program the Special

Codec to be under line operations and all other specific

operations of DAM. To enhance an easy read/write of

control registers by microprocessors, the control data

is clocked by the 8 kHz sampling clock and synchro-

nized by SDEN\, where SDEN\ is coming from the

output port of microprocessor by detecting one of the

rising edge of 8 kHz clock.
