Si3050
Functional Description
The Si3050 is an integrated direct access arrangement
(DAA) providing a programmable line interface that
meets global telephone line requirements. The Si3050
implements Silicon Laboratories’ proprietary ISOcap™
technology, which offers the highest level of integration
by replacing an analog front end (AFE), an isolation
transformer, relays, opto-isolators, and a 2- to 4-wire
hybrid with two thin small shrink outline packages
(TSSOPs).
The Si3050 DAA is fully software programmable to meet
global requirements and is compliant with FCC, TBR21,
JATE, and other country-specific PTT specifications as
shown in Table 13. In addition, the Si3050 meets the
most stringent global requirements for out-of-band
energy, emissions, immunity, high-voltage surges, and
safety, including FCC Parts 15 and 68, EN55022,
EN55024, and many other standards.
Line-Side Device Support
