Si3218x Data Short: ProSLIC

Single-Chip

FXS Solution

The Si3218x devices are pin-compatible single-channel ProSLIC

products that imple-

ment a complete foreign exchange station (FXS) telephony interface solution in accord-

ance with all relevant global specifications. The Si3218x ProSLIC ICs operate from a 3.3

V supply and interface to standard PCM/SPI or 3-wire ISI digital interfaces with 3.3 V or

1.8 V I/O. The Si3218x integrated dc-dc controller automatically generates the optimal

battery voltages required for each linestate. Si3218x ICs are available with voltage rating

of –106 V. The Si3218x devices are available in a 5x6 mm 36-pin QFN package and a

6x6 mm 40-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)
