ICS1660 Incoming Call Line Identification (ICLID) Receiver with Ring Detection

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 components, amplifies, filters and demodulates the FSK data transmi.
