Description
The
programmable line interface to meet global telephone line requirements. Available
in one 20-pin and one 16-pin TSSOP, it eliminates the need for an analog front
end (AFE), an isolation transformer, relays, opto-isolators, and a 2- to 4-wire
hybrid. The Si3050 dramatically reduces discrete components and the cost
required to comply with global regulatory requirements. The Si3050 interfaces
directly to standard telephony PCM interfaces.
