73M1966 Product Brief  
73M1966  
Foreign-Exchange-Office Chip Set  
The Teridian 73M1966 is a two chip solution 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 73M1966 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  
73M1966 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.

The chip set constitutes two separate devices that provide the necessary functionality and  
the protection required for worldwide homologation. The 73M1906 is a host side device  
and provides the digital data and control interfaces. The 73M1916 is the line side device.

With better than 2.0 in2 (10.2 cm2) board area and a very competitive BOM cost, a complete  
universal FXO may be realized with only a few additional standard external components.  
ꢀResidential/CPEꢀgateways  
Suitable applications for the 73M1966 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 73M1966 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.
