73M1822 Product Brief

73M1822 MicroDAA^™

The Teridian 73M1822 is a single chip package of the 73M1922 chip set that uses

Teridian’s unique data access arrangement (DAA) function designed for voice band data

and fax modems.

The 73M1822 MicroDAA™ is the first single chip silicon direct access arrangement for

data/fax modem and voice applications. It provides a serial MAFE interface to popular DSP/

host processors to implement a globally compliant cost effective soft modem solution.

Key Applications

ꢀ

Highꢀspeedꢀvoiceꢀbandꢀdataꢀmodems

The 73M1822 offers software programmable AC/DC terminations, types I and II caller ID,

billing tone filter, ring detection, polarity reversal detection, line voltage and current moni-

toring, call progress monitoring and pulse dialing.

ꢀ

PointꢀofꢀSaleꢀTerminalsꢀ

Internally the device constitutes two separate functional units that provide the necessary

functionality and the protection required for worldwide homologation.

asꢀmedicalꢀandꢀindustrialꢀtelemetry.

With better than 2.0 in²(10.2 cm²) board area and a very competitive BOM cost, a

complete universal DAA may be realized with only a few standard external components.

Suitable applications for the 73M1822 include set top boxes, low to high speed (PCM)

voice band data modems, point of sales terminals, fax and multi-function peripherals,

text telephony, embedded telemetry (industrial and medical) etc.

Based on an innovative and patented technology which sets new standards in reliability

and cost. A small pulse transformer forms a digital isolation barrier, transferring both

power and data to the PSTN line side components. This results in reliable performance

in presence of EMI as a tolerance to line voltage variations by providing power to the line

side across the barrier thus enhancing overall performance.

Overall the 73M1822 provides a highly efficient solution for high performance.

Teridian Semiconductor Corporation is a modem technology pioneer and Silicon DAA

patent holder with a long history of development and innovation including the capacitive

isolation barrier technology licensed to 3rd parties and has been globally deployed in low

speed and high speed analog modems.
