Description
The Si3016 is an integrated direct access arrangement (DAA) line-side
device 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 Si3016
dramatically reduces the number of discrete components and cost
required to achieve compliance with global regulatory requirements. The
Si3016 interfaces directly to a Silicon Laboratories integrated DAA
system-side interface.
