DESCRIPTION
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.
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.
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.
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.
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.
