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), an 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.
