Si3217x and Si3291x

ProSLIC® Single-Chip FXS Solution with FXO Option

Description

- Low power standby operation

The Si3217x is a family of pin-compatible single-channel

ProSLIC products that implement a complete foreign

exchange station (FXS) telephony interface solution in

accordance with all relevant LSSGR, ITU and ETSI

specifications. Select parts in the series also implement

Silicon Laboratories' patented capacitive isolation

technology to enable seamless connection to Si3291x

series foreign exchange office (FXO) line-side devices. The

Si3217x ProSLIC ICs operate from a 3.3 V supply and

interface to standard PCM/SPI digital interfaces. The

Si3217x integrated dc-dc controller automatically

generates the optimal battery voltages required for each

line-state. Si3217x ICs are available with voltage ratings of

–110 V or –135 V to support a wide range of ringing

voltages. The Si3217x is available in a 5x7 mm 42-pin QFN

package. The Si3291x is available in a 16-pin SOIC

package.
