PCD3316 Caller-ID on Call Waiting CIDCW receiver

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.
