FEATURES
DESCRIPTION
The NW6005 device is a single-chip, 3/5 Volt CMOS caller ID with call waiting detection circuit. It can receive signals following Bellcore GR-30-CORE & SR-TSV-002476, BT SIN227 & SIN242, and ETSI ETS 300 788-1/-2 specifications. The NW6005 provides 1200 baud Bell 202 and ITU-T V.23 FSK demodulation and CAS/DT-AS detection. Two seperate differential input amplifiers allow the device to be connected with both Tip/Ring and Telephone Hybrid receive pair. FSK demodulation is implemented only on Tip/Ring, while DT-AS (or CAS) detection can be on either Tip/Ring or Hybrid Receive. In addition, NW6005 provides a serial FSK data interface via which the data can be selected to be processed as a bit stream or extracted from a 1 byte built-in buffer. 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, answering machines, database query systems and Computer Telephony Integration (CTI) systems.
1200 baud Bell 202 and ITU-T V.23 Frequency Shift Keying (FSK) Demodulation Compliant with following specifications: Bellcore GR-30-CORE & SR-TSV-002476 TIA/EIA-716, TIA/EIA-777 Draft British Telecom (BT) SIN227 & SIN242 ETSI ETS 300 778-1 and -2 Bellcore “CPE Alerting Signal (CAS)”, British Telecom “Idle State and Loop State Tone Alert S...
