SI3200-KS - Brand New SILICON LABS Telecommunication Interface ICs
-
Description
The Si3200-KS is a low-voltage CMOS SLIC that offers a low-cost, fully software programmable, dual-channel, analog telephone interface for customer premise (CPE) applications. It eliminates the need for centralized ringers and ringing relays with internal ringing generation. It also allows remote line card and loop diagnostics with on-chip subscriber loop testing, eliminating the need for external test equipment or relays. The Si3200-KS performs all programmable SLIC functions in compliance with all relevant LSSGR, ITU, and ETSI specifications, while all high-voltage functions are performed by the Si3200 linefeed interface IC.
