Teridian intros world’s first single-package DAA modem solution

Teridian Semiconductor’s 73M1822 and 73M1922 MicroDAA chipsets are solutions that incorporate direct access arrangement (DAA) technology for data/fax modem and voice applications, and provide the necessary functionality and protection required for worldwide homologation. These devices are ideal for applications such as high-speed voice band data modems, satellite set-top boxes, fax/multifunction peripherals (MFP), point-of-sale (POS) terminals, and other embedded modem applications.

The 73M1822 is the first single package silicon DAA solution. It uses an inexpensive common pulse transformer that forms a digital isolation barrier, transferring both power and data to the PSTN line side components. This technology is also available for extended isolation requirements as a chip set, 73M1922. The result is reliable performance in the presence of EMI and line voltage variations.
