Description
The Si3232 is a low-voltage CMOS SLIC that offers a low-cost, fully software-
programmable, dual-channel, analog telephone interface for customer premise
(CPE) applications. Internal ringing generation eliminates centralized ringers and
ringing relays, and on-chip subscriber loop testing allows remote line card and
loop diagnostics with no external test equipment or relays. The Si3232 performs
all programmable SLIC functions in compliance with all relevant LSSGR, ITU, and
ETSI specifications; all high-voltage functions are performed by the Si3200
linefeed interface IC. The Si3232 operates from a single 3.3 V supply and
interfaces to a standard SPI bus digital interface for control. The Si3200 operates
from a 3.3 V supply as well as high-voltage battery supplies up to 100 V. The
Si3232 is available in a 64-pin thin quad flat package (TQFP), and the Si3200 is
available in a thermally-enhanced 16-pin small-outline (SOIC) package.
