NW6005

Enhanced Type II Caller ID Decoder

Data Sheet, June 2000 (Ver 3.1)

File No. NW6005DS(L)

Description

Features

The NW6005 device is a single-chip, 3/5 Volt CMOS caller ID

with call waiting detection circuit. It can receive signals follow-

ing Bellcore GR-30-CORE & SR-TSV-002476, BT SIN227 &

SIN242, and ETSI ETS 300 788-1/-2 specifications.

♦

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 “CPEAlerting Signal (CAS)”, British Telecom “Idle

State and Loop State Tone Alert Signal” and ETSI “Dual

ToneAlerting Signal (DT-AS)” detection

Two seperate OP amps with adjustable gain for Tip/Ring

and Telephone Hybrid connections

Monitoring of the stop bit for framing error check

Serial FSK data interface with selectable output of bit

stream or 1 byte buffer

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 Re-

ceive. In addition, NW6005 provides a serial FSK data inter-

face 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.

♦

FSK carrier detection

3 V or 5 V operation

Low power CMOS with intelligent powerdown mode

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