Description

The Si306x is an integrated direct access arrangement (DAA) with a

programmable line interface to meet global telephone line interface

requirements. Available in a 16-pin small outline package, it eliminates

the need for an analog front end (AFE), an isolation transformer, relays,

opto-isolators, and a 2- to 4-wire hybrid. The Si306x dramatically reduces

the number of discrete components and cost required to achieve

compliance with global regulatory requirements. The Si306x interfaces

directly to a Silicon Laboratories integrated DAA system-side module.
