Description
The NW6003 device is a single-chip, 3/5 Volt CMOS caller
ID and call waiting detection circuit. It can receive signals
following Bellcore GR-30-CORE & SR-TSV-002476, BT
SIN227 & SIN242, and CCA TW/P&E/312 specifications.
The NW6003 provides 1200 baud Bell 202 and ITU-T V.23
FSK demodulation. It allows a microcontroller to extract data
from it via a serial interface. In addition, the NW6003 offers
Idle State and Loop State Tone Alert Signal and line reversal
detection capability for BT CLIP, ring burst detection for the
CCA CLIP, and ring and CAS detection for Bellcore CID.
The device can be used in feature or cordless phones for BT
Calling Line Identity Presentation (CLIP), CCA CLIP and
Bellcore Calling Identity Delivery (CID) systems. It can also
be used in caller ID boxes, modem, fax machines, answer-
ing machines, database query systems and Computer Tele-
phony Integration (CTI) systems.
