SI32282-A-FM

Si3228x Data Short The Si3228x Dual ProSLIC® devices, in a single package, implement two complete foreign exchange station (FXS) telephony interfaces. The Si3228x devices operate from a 3.3 V supply and have standard PCM/SPI or 3-wire ISI digital interfaces. A pair of built-in dc-dc converter controllers can be used to automatically generate the optimal battery voltage required for each line-state, optimizing efficiency and minimizing heat generation. 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 reduces 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 package.
