Si3229x: ProSLIC Single-Chip Dual FXS Solution The Si3229x Dual ProSLIC devices, in a single package, implement two complete foreign exchange station (FXS) telephony interfaces. The Si3229x devices operate from KEY FEATURES 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 Two complete FXS channels in a single 8x8 mm package battery voltage required for each line-state, optimizing efficiency and minimizing heat generation. The Si3229x devices are designed to operate with capacitive ultra-boost Performs all BORSCHT functions tracking battery supply for lower power, cost, and footprint vs. other tracking or shared Ultra-low power consumption battery supplies in the industry. Self-testing and metallic loop testing (MLT) is facilitated Patented low-power ringing by the built-in DSP, monitor ADC, and test load. The devices are available with wide- Patented Smart Ringing option band audio for better than PSTN voice quality, DTMF detection, and Smart Ringing. Reduces peak current with 2-channel Smart Ringing reduces the peak current with 2-channel ringing for lower-cost ac-dc ringing (Si32295/7) adapters. The Si3229x devices are available in an 8 x 8 mm 68-pin QFN package.
