Applications

Description

The Si3056 is an integrated direct access arrangement (DAA) with a

programmable line interface to meet global telephone line requirements. Available

in two 16-pin small outline packages, it eliminates the need for an analog front end

(AFE), isolation transformer, relays, opto-isolators, and a 2- to 4-wire hybrid. The

Si3056 dramatically reduces the number of discrete components and cost

required to achieve compliance with global regulatory requirements. The Si3056

interfaces directly to standard modem DSPs.
