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
Three different line-side devices are available for use
with the Si3050 system-side device. The Si3011
line-side device has been optimized for TBR21 and
FCC-compliant countries. The Si3018 and Si3019
line-side devices are globally compliant, have a
selectable 5 Hz or 200 Hz RX high-pass filter pole, and
offer a –16.5 to 13.5 dB digital gain/attenuation
adjustment in 0.1dB increments for the transmit and
receive paths.
