73M1866B/73M1966B  
MicroDAA™ with PCM Highway  
DATA SHEET  
April 2010  
Simplifying System Integration™  
DS_1x66B_001  
DESCRIPTION  
Through its PCM interface, the 73M1966B can  
be connected to other PCM enabled devices  
such as POTS codecs, ISDN codecs, E1/T1  
framers, etc.  
The 73M1866B and 73M1966B use the Teridian  
patented Data Access Arrangement function  
(MicroDAA®) designed exclusively for Foreign-  
Exchange-Office (FXO) in Voice-over-IP (VoIP)  
applications. These devices provide much of the  
circuitry required to connect PCM formatted  
voice channels to a PSTN via a two-wire twisted  
pair interface. The package options provide the  
necessary functional programmability and  
protection required for easy worldwide  
Additional DAA functions supported by the  
73M1x66B devices include a call progress  
monitor, Caller ID Type I and II, ring detection,  
pulse dialing, billing tone detection and polarity  
reversal detection.

The family of devices consists of the 73M1866B  
and the 73M1966B. The 73M1866B MicroDAA  
is the world’s first single-package silicon Data  
Access Arrangement (DAA). Suitable  
applications for the 73M1866B and 73M1966B  
devices include VoIP equipment that must  
provide connectivity to the PSTN for purposes of  
guaranteeing emergency service calling,  
redundancy for supplementary connectivity for  
voice, and maintenance services.  
FEATURES

•
PCM highway data interface supporting both  
slave and master modes  
PCM highway interface supporting both E-1  
and T-1  
SPI control interface, with daisy chain  
support for up to 16 devices  
Designed to meet global DAA compliance  
FCC, ETSI ES 203 021-2, JATE and other  
PTT standards.  
The 73M1966B device set consists of the  
73M1906B Host-Side Device that provides digital  
data, control interfaces and power to the  
73M1916 Line-Side Device.  
These devices are 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 method results in reliable  
operation in the presence of EMI and a tolerance  
to line voltage variations by providing power to  
the Line-Side Device across the barrier. The  
devices also support the ability to provide up to  
an additional +6 dB of analog gain to the line-  
side transmit and +3 dB in the receive signal  
paths. The device supports transmit and receive  
digital gain ranging from –18 dB to +7.375 dB by  
increments of 0.125 dB.

The digital side provides a PCM highway  
interface with automatic clock rate detection.  
With an 8-kHz sampling rate, the devices include  
an ITU-T G.711 compliant codec with selectable  
µ-law and A-law companding modes. The  
devices also provide a 16-bit linear mode, which  
is suitable for interfacing with wide band codecs,  
as well as 16 kHz sampling rate. Device control  
is performed over an SPI interface. The SPI  
supports daisy chain operation.
