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.
