NW6003

Type II Caller ID Decoder

Data Sheet, January 2000 (Ver 2.0)

File No. NW6003DS(L)

Description

Features

♦

1200 baud Bell 202 and ITU-T V.23 Frequency Shift

Keying (FSK) Demodulation

Compliant with three specifications:

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

British Telecom (BT) SIN227 & SIN242

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.

Cable Communication Association (CCA) TW/P&E/312 The NW6003 provides 1200 baud Bell 202 and ITU-T V.23

Bellcore “CPEAlerting Signal (CAS)” and British Telecom FSK demodulation. It allows a microcontroller to extract data

“Idle State and Loop State Tone Alert Signal” detection from it via a serial interface. In addition, the NW6003 offers

♦

Ring and line reversal detection

High sensitivity with -40 dBV input Tone and FSK

Detection

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.

♦

Serial data interface to microcontroller

3 V ±10% or 5 V ±10% operation

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, answer-

ing machines, database query systems and Computer Tele-

phony Integration (CTI) systems.
