TYPE II CALLER ID DECODER

FEATURES

DESCRIPTION

1200 baud Bell 202 and ITU-T V.23 Frequency Shift Keying (FSK)

Demodulation

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.

Compliant with three specifications:

Bellcore GR-30-CORE & SR-TSV-002476

British Telecom (BT) SIN227 & SIN242

Cable Communication Association (CCA) TW/P&E/312

Bellcore “CPE Alerting Signal (CAS)” and British Telecom “Idle

State and Loop State Tone Alert Signal” detection

Ring and line reversal detection

High sensitivity with -40 dBV input Tone and FSK Detection

Serial data interface to microcontroller

3 V ±10% or 5 V ±10% operation

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.

Low power CMOS with powerdown mode

Operating temperature range: -40 °C to +85 °C

Packages available:

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.
