ICS1660 Overview
The ICS1660 “ICLID” circuit is a monolithic CMOS VLSI device that decodes and detects the Frequency Shift Keying (FSK) signals used in caller identification telephone service. The ICS1660, when used in conjunction with some external ponents, amplifies, filters and demodulates the FSK data transmitted from the central office to the telephone subscriber. The ICS1660 detects the first power ring signal and demodulates...
