Datasheet Summary
Caller-ID on Call Waiting (CIDCW) receiver
11 March 1999 Product specification
1. General description
The PCD3316 is a low power mixed signal CMOS integrated circuit for receiving physical layer signals like Bellcore’s ‘CPE1 Alerting Signal (CAS)’ and the signals used in similar services. The device is capable of a very high precision detection of the dual tone (2130 and 2750 Hz) by using a patented digital algorithm. The PCD3316 can be used for on-hook and off-hook Caller-ID (CID), Caller-ID on Call Waiting (CIDCW) and Caller-Name (CNAM) applications. For timing purposes the PCD3316 can be programmed to generate an interrupt signal to the microcontroller every second or every...
