Si3245/Si3203
Quad ProSLIC® Programmable CMOS SLIC/Codec
- Software programmable parameters:
Description
®
- Two-wire ac impedance
- Transhybrid balance
- DC current loop feed (10–50 mA)
- Loop closure and ring trip thresholds
- Ground key detect threshold
- Power alarms
The Quad ProSLIC is a series of low-voltage CMOS
devices that integrate both SLIC and codec
functionality into a single IC to provide a complete
four-channel analog telephone interface in
accordance with all relevant Telcordia, ITU, and ETSI
specifications. The Si3245 supports centralized
ringing for long loop and legacy applications. On-chip
subscriber loop and audio testing allows remote
diagnostics and fault detection with no external test
equipment or relays. The Quad ProSLIC devices
operate from a single 3.3 V supply and interface to
standard PCM/SPI or GCI bus digital interfaces. The
Si3203 linefeed interface IC performs all high-voltage
functions and operates from a 3.3 V supply as well
as three battery supplies up to –110 V. The Quad
ProSLIC devices are available in a 100-pin thin quad
flat package (TQFP), and the Si3203 is available in a
thermally-enhanced 48-pin thin quad flat package
(TQFP) or 40-pin quad flat no-lead (QFN) package.
