Si3229x: ProSLIC

Single-Chip Dual FXS

Solution

The Si3229x Dual ProSLIC® devices, in a single package, implement two complete for-

eign exchange station (FXS) telephony interfaces. The Si3229x 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 genera-

tion. 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.

Applications:

• VoIP gateways and routers

• xDSL IADs

• Optical Network Terminals/Units (ONT/U)

• Analog Terminal Adapters (ATA)

• Cable eMTA

• Wireless Fixed Terminals (WFT)

• Wireless Local Loop (WLL)

• WiMAX CPE

• Private Branch Exchange (PBX)

• VoIP MDU gateways
