Si3228x Data Short: ProSLIC Single-Chip

Dual FXS Solution

The Si3228x Dual ProSLIC® devices, in a single package, implement two complete for-

eign exchange station (FXS) telephony interfaces. The Si3228x devices operate from a

KEY FEATURES

3.3 V supply and have standard PCM/SPI or 3-wire ISI digital interfaces. A pair of built-in

• Two complete FXS channels in a single 7x7

or 8x8 mm package

dc-dc converter controllers can be used to automatically generate the optimal battery

voltage required for each line-state, optimizing efficiency and minimizing heat genera-

tion. The Si3228x devices are designed to operate with capacitive boost tracking battery

supply for lower power, cost, and footprint vs. other tracking or shared battery supplies

in the industry. Self-testing and metallic loop testing (MLT) is facilitated by the built-in

DSP, monitor ADC, and test load. The devices are available with wideband audio for

better than PSTN voice quality, DTMF detection, and Smart Ringing. Smart Ringing re-

duces the peak current with 2-channel ringing for lower-cost ac-dc adapters. The

Si3228x devices are available in a 7 x 7 mm 48-pin QFN or 8 x 8 mm 56-pin QFN pack-

age.
