1 / 94 page Rev. 1.05 6/05 Copyright © 2005 by Silicon Laboratories Si3056 Si3056 Si3018/19/10 GLOBAL SERIAL INTERFACE DIRECT ACCESS ARRANGEMENT Features Complete DAA includes the following: 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.
