Si3050 + Si3018/19
5. 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’ patented isolation
capacitor 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 highly-integrated ICs.
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.
5.1. Line-Side Device Support
