Si3218x: ProSLIC® Single FXS Solution
ProSLIC® Single-Channel FXS Solutions
The Si3218x Single FXS ProSLIC® devices implement a complete foreign exchange
station (FXS) telephony interface solution in a single package that conforms to all
relevant global specifications. The Si3218x ProSLIC ICs operate from a 3.3 V supply
and have standard PCM/SPI or 3-wire ISI digital interfaces with 3.3 V or 1.8 V I/O. The
Si3218x devices are designed to operate with a capacitive boost tracking battery supply
for lower power, cost, and footprint than other tracking supplies in the industry. Self-test-
ing and metallic loop testing (MLT) are facilitated by the built-in DSP, monitor ADC, and
test load. The devices are available with wideband audio for better-than-PSTN voice
quality and DTMF detection. The Si3218x devices are available in 5 x 6 mm, 36-pin
QFN and 6 x 6 mm, 40-pin QFN Packages.
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
