Si3229x: ProSLIC® Single-Chip Dual FXS Solution
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 Si3229x devices are designed to operate with capacitive ultra-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
Si3229x devices are available in an 8 x 8 mm 68-pin QFN package.
