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.
