Product Details

Description

The Si3232 is a low-voltage CMOS SLIC that offers a low-cost, fully software programmable, dual-channel, analog telephone interface for customer premise (CPE) applications. Internal ringing generation eliminates centralized ringers and ringing relays, and on-chip subscriber loop testing allows remote line card and loop diagnostics with no external test equipment or relays. The Si3232 performs all programmable SLIC functions in compliance with all relevant LSSGR, ITU, and ETSI specifications; all high-voltage functions are performed by the Si3200 linefeed interface IC.

Features

Ideal for customer premise applications
Low standby power consumption: <65 mW per channel
Internal balanced ringing to 65 Vrms
Software programmable parameters:
Ringing frequency, amplitude, cadence, and waveshape
Two-wire ac impedance
DC loop feed (18â€“45 mA)
Loop closure and ring trip thresholds
Ground key detect threshold
Automatic switching of up to three battery supplies
On-hook transmission
Loop or ground start operation with smooth/abrupt polarity reversal
SPI bus digital interface with programmable interrupts
3.3 V operation
GR-909 loop diagnostics and loopback testing
12 kHz/16 kHz pulse metering
Lead-free/RoHS compatible packages available
