Description

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 transmitted from the central office to the telephone

subscriber.

The ICS1660 detects the first power ring signal and demodu-

lates the 1200 baud FSK data transmitted during the silent

interval between the first and second power ring. The FSK data

is transmitted from the central office switch to the subscriber

line as part of the CLASS service of Calling Number Delivery

(CND). This data is then demodulated, amplified and filtered

by the ICS1660 and digitally transmitted to the host control-

ler/processor.

The ICS1660 is designed to be powered by any off-the-shelf

9.0 volt battery. The on-chip 5.0 voltage regulator powers the

host microprocessor and any external circuitry supported by

the ICS1660. This portion of the circuit can be overridden by

connecting the VIN pin (18) to the VDD pin (1) for a common

power supply. A low battery detection circuit is also provided

on-chip and signals the microprocessor on the FSK/BAT pin

(17) when the PWR pin (16) input is pulled low.
