Product Summary
The si3056-d-fsr is an integrated direct access arrangement (DAA) with aprogrammable line interface to meet global telephone line requirements. Available in two 16-pin small outline packages. The si3056-d-fsr eliminates the need for an analog front end (AFE), isolation transformer, relays, opto-isolators, and a 2- to 4-wire hybrid. The si3056-d-fsr dramatically reduces the number of discrete components and cost required to achieve compliance with global regulatory requirements. The si3056-d-fsr interfaces directly to standard modem DSPs. The applications of the si3056-d-fsr include V.92 modems, Voice mail systems, Multi-function printers, Set-top boxes, Fax machines, Internet appliances, Personal digital assistants.
