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  tate 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 NW6003 can be used in feature or cordless phones for BT Calling Line Identity Presentation (CLIP), CCA CLIP and Bellcore Calling Identity Delivery (CID) systems. NW6003 can also be used in  caller ID boxes, modem, fax machines, answering machines, database query systems and Computer Telephony Integration (CTI) systems.
