PCD3316
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 minute. These timings are derived
from an on-chip 32.768 kHz oscillator.
Also incorporated in the device are a Frequency Shift Keying (FSK)
receiver/demodulator and a ‘Ring or polarity change detector’. The status of the
PCD3316, the received FSK data bytes and the ringer period can be read and many
options can be selected via the I2C-bus serial interface. Two on-chip oscillators are
available. One 3.58 MHz oscillator for all internal functions and a low frequency
32.768 kHz oscillator for the 1 second or 1 minute timing.
In Power-down mode only the polarity comparators and the 32.768 kHz oscillator are
c active. The CAS detection, the FSK receiver and the 3.58 MHz oscillator can be
c
enabled separately. Detection of a polarity change on the inputs POL0 or POL1, the
reception of an FSK data byte, the detection of a CAS tone or a timebase interrupt is
signalled to the microcontroller by an interrupt request signal (IRQ). The
microcontroller can communicate with the PCD3316 device via the serial interface.
The PCD3316 is designed for use in a microcontroller controlled system. The device
is available in a SO16 package.
A demonstration board OM5843 and an application note AN98071 are available.
