SI3062 Datasheet | Silicon Labs

Features plete DAA includes the following: 80 d B dynamic range TX/RX paths to support up to V.92 modem speeds Programmable line interface AC termination DC termination Ring detect threshold Ringer impedance Integrated codec and 2- to 4-wire analog hybrid Integrated ring detector Pulse dialing support Billing tone detection Overload detection > 5000 V isolation Proprietary isolation interface to integrated DAA module Line voltage monitor Loop current monitor Caller ID support Low-profile SOIC available in leadfree/ROHS-pliant packages Ordering Information See page 59. 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 ponents and cost required to achieve pliance with global regulatory requirements. The Si306x interfaces directly to a Silicon Laboratories integrated DAA system-side module.
