Applications V.92 soft modems PDAs Set-top boxes Fax machines POS terminals Multi-function Printers 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.
