Figure 20. Si3050 + Si3011/18/19 Functional Block Diagram
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 only supports DC terminations
compliant with 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.
5.1.1. Si3011
TBR-21 and FCC-compliant line-side device.
Selectable dc terminations.
Two selectable ac terminations to increase return loss
and trans-hybrid loss performance.
+6 dBm TX/RX level mode (600 )
5.1.2. Si3018
Globally-compliant line-side device—targets global
DAA requirements for voice applications. This
line-side device supports both FCC-compliant
countries and non-FCC-compliant countries.
Selectable dc terminations.
Four selectable ac terminations to increase return loss
and trans-hybrid loss performance.
+6 dBm TX/RX level mode (600 )
5.1.3. Si3019
Globally-compliant, enhanced features line-side
device—targets global DAA requirements for voice
applications.
Selectable dc terminations
Sixteen selectable ac terminations to further increase
return loss and trans-hybrid loss performance.
Line voltage monitoring in on- and off-hook modes to
enable line in-use/parallel handset detection.
Programmable line current / voltage threshold interrupt.
Polarity reversal interrupt.
+3.2 dBm TX/RX level mode (600 )
+6 dBm TX/RX level mode (600 )
Higher resolution (1.1 mA/bit) loop current
measurement.
