Description

See page 38.

The Si3226/27 Dual ProSLIC® chipsets each consist of a low-voltage CMOS

device integrating both SLIC and CODEC functionality in combination with a high-

voltage linefeed IC (LFIC). The chipset provides two complete foreign exchange

station (FXS) telephony interfaces. The Si3226/27 operate from a single 3.3 V

supply and interface to standard PCM/SPI or GCI bus digital interfaces. A built-in

dc-dc controller automatically generates the optimal battery voltage required for

each line-state, optimizing efficiency and minimizing heat generation. Self-testing

and metallic loop testing (MLT), e.g., GR-909, is facilitated by the built-in DSP,

monitor ADC, and test load. The companion Si3208/09 LFICs are available with

voltage ratings up to –135 V to support high power ringing and the Si3227

supports wideband audio for better-than-PSTN voice quality (see Ordering Guide

below). The Si3226/27 are available in a 64-pin thin quad flat package (TQFP);

the LFICs are available in a 40-pin quad, flat, no-lead package (QFN).
