Description
®
- Ringing frequency, amplitude, cadence, and wave-
shape
- Two-wire ac impedance
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 Si3241 includes internal ringing
generation to eliminate centralized ringers and
ringing relays. 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 Si3206/3 linefeed interface IC
performs all high-voltage functions and operates
from a 3.3 V supply as well as three battery supplies
up to –135/–110 V. The Quad ProSLIC devices are
available in a 100-pin thin quad flat package (TQFP),
and the Si3206/3 is available in a thermally-
enhanced 48-pin thin quad flat package (TQFP) or
40-pin quad flat no-lead (QFN) package.
