73M1866 Product Brief
73M1866
Foreign-Exchange-Office
The Teridian 73M1866 is a single chip package of the 73M1966 chip set that uses
Teridian’s unique data access arrangement (DAA) function designed exclusively for
Foreign-Exchange-Office (FXO) of Voice-over-IP (VoIP) systems. The device provides
most of the circuitry to connect PCM formatted voice channels to a PSTN via a two
wire twisted pair interface.
Key Applications
The 73M1866 interfaces through simple standard interfaces. A PCM Highway interface
provides the data path and device control is provided by an SPI. These interfaces allow the
73M1866 to be easily connected and controlled with other similar devices connected to
the PCM highway and SPI such as POTS Codecs, ISDN Codecs, T1/E1 framers, etc.

Suitable applications for the 73M1866 include VoIP equipment that have a need to
provide connectivity to the PSTN for purposes of guaranteeing emergency service calling,
redundancy for supplementary connectivity for voice, maintenance services.
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 and a tolerance to line voltage variations by providing power to the line
side across the barrier thus enhancing overall performance.
Overall the 73M1866 provides a highly efficient solution for performance…
Teridian Semiconductor Corporation is a Silicon DAA technology pioneer and 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.
