Description

The Dual ProSLIC

devices that integrate both SLIC and CODEC

functionality into a single IC. In combination with a

linefeed IC (LFIC), they provide a complete two-

channel analog telephone interface in accordance

with

specifications. The Dual ProSLIC devices (Si3226/7)

operate from a single 3.3 V supply and interface to

standard PCM/SPI or GCI bus digital interfaces. The

LFICs (Si3208/9) perform all high-voltage functions

and operate from a 3.3 V supply as well as high-

voltage battery supplies. The Si3208 is rated for –

110 V, and the Si3209 is rated for –135 V. The Dual

ProSLIC devices are available in a 64-pin thin quad

flat package (TQFP), and the LFICs are available in a

40-pin, quad flat no-lead package (QFN).

Features
