ProSLIC® Single-Chip FXS Solution with FXO Option
Description
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.
