Description
The Dual ProSLIC is a series of low-voltage CMOS devices that integrate both
SLIC and codec functionality into a single IC to provide a complete dual-channel
analog telephone interface in accordance with all relevant LSSGR, ITU, and ETSI
specifications. The Si3220 includes internal ringing generation to eliminate
centralized ringers and ringing relays, and the Si3225 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 Si3220 and Si3225 operate from a single 3.3 or 5 V supply and
interface to standard PCM/SPI or GCI bus digital interfaces. The Si3200/2 linefeed
ICs perform all high-voltage functions and operate from a 3.3 or 5 V supply as well
as single or dual battery supplies up to 100 V (Si3200) or 125 V (Si3202). The
Si3220 and Si3225 are available in a 64-pin thin quad flat package (TQFP), and the
Si3200/2 is available in a thermally-enhanced 16-pin small outline (SOIC) package.
