73M1822/73M1922 MicroDAA

Silicon DAA with Serial Interface

DATA SHEET

Simplifying System Integration™

DS_1x22_001

DESCRIPTION

April 2010

APPLICATIONS

The 73M1822 MicroDAA is the world’s first

single-package silicon Data Access Arrangement

(DAA) for data/fax modem and voice applications.

It provides a serial Modem Analog Front End

(MAFE) interface to popular DSP/host processors to

implement a globally compliant low-cost soft modem

solution.

•

V.92 modems

Satellite Set Top Boxes

Fax/Multifunction Peripherals (MFP)

Point of Sale Terminals

Voicemail Systems

Industrial and medical telemetry

FEATURES

The 73M1822 MicroDAA is available as a

two-chip configuration (the 73M1922) that consists

of a 73M1902 Host-Side Device and a 73M1912

Line-Side Device. The MicroDAA integrates all

codec and DAA functions necessary to achieve

reliable PSTN connection worldwide.

•

Meets FCC, ETSI ES 203 021-2, JATE, NET4

and other PTT standards

•

Configurable PSTN termination

Up to 8 mA minimum line current operation

0 dBm Transmit/Receive full scale

THD –80 dB

16-bit codec up to 16 kHz sample rate

Up to 56 Kbps (V.92) performance

Configurable sample rates (7.2 – 16 kHz)

Reference clock range of 9-40 MHz

Crystal frequency range of 9-27 MHz

The MicroDAA uses a small pulse transformer,

which can achieve more than 6 kV isolation. Power

may be supplied along with data through this barrier

interface to achieve superior performance in weak

loop current conditions. Inherently immune to RFI

and other forms of common mode interference, the

patented MicroDAA technology achieves global DAA

compliance with unparalleled flexibility, reliability,

and cost structure and requires less than 2 square

inches of a single sided PCB.

MAFE I/F with Master, Slave and Daisy

Chaining

•

Billing tone reject filter

Polarity reversal detection on-chip

GPIO for user-configurable I/O port

Call Progress Monitor

3.3 V Operation

Industrial temperature range (-40° to +85° C)

6 kV isolation (73M1922)

4-5 kV isolation (73M1822)

8x8 mm 42-pin QFN (73M1822)

20-pin TSSOP or 5x5 mm 32-pin QFN

(73M1922)

The MicroDAA supports Caller ID Type I and II, ring

detection, tip/ring polarity reversal detection, hook

switch control, pulse dialing, regulation of loop

current (DC mask), configurable line impedance

matching, line in use and parallel pickup detection.

The MicroDAA integrates billing tone filters, external

clock reference, audio monitor output, and requires

only a small number of low cost and commonly

available external components.

•

RoHS compliant (6/6) lead-free package

The MicroDAA incorporates a configurable sample

rate circuit to support soft modem and

DSP-based implementations of all speeds up to

V.92 (56 Kbps). Sampling rates from 7.2 kHz to

16 kHz can be easily supported.
