Features

Applications

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.
