The Dual
is a family of low-voltage CMOS
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 all relevant LSSGR, ITU, and ETSI
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).
