LITELINK™ III Phone Line Interface IC (DAA)

Features

Description

• Superior voice solution with high power option, low

noise, no automatic gain control circuit, and excel-

lent part-to-part gain accuracy

LITELINK III is a single-package silicon phone line

interface/DAA used in voice and data communication

applications to make connections between host equip-

ment and telephone networks.

•

Data access arrangement (DAA) solution for modems at

speeds up to V.92

LITELINK provides a high-voltage isolation barrier, AC

and DC phone line termination, switchhook, 2-wire to

4-wire hybrid, ring detection, and on-hook signal

detection. LITELINK can be used in both differential

and single-ended signal applications.

• 3.3 or 5 V power supply operation

• Caller ID signal reception function

• Easy interface with modem ICs and voice CODECs

• Worldwide dial-up telephone network compatibility

• Supplied application circuit complies with the

requirements of TIA/EIA/IS-968 (FCC part 68),

UL1950, UL60950, EN60950, IEC60950,

EN55022B, CISPR22B, EN55024, and TBR-21

• Complies with UL1577

• Line-side circuit powered from telephone line

• Compared to other silicon DAA solutions, LITELINK:

- Uses fewer passive components

LITELINK uses on-chip optical components and a few

inexpensive external components to form a complete

voice or high-speed data phone line interface.

LITELINK eliminates the need for the large isolation

transformers or capacitors used in other interface con-

figurations. It incorporates the required high-voltage

isolation barrier in the surface-mount SOIC package.

- Takes up less printed-circuit board space

- Uses less telephone line power

- Offers simplified operation

The CPC5620 (half-wave ring detect) and CPC5621

(full-wave ring detect) PLIs build upon Clare’s

LITELINK II line, with improved insertion loss control,

improved noise performance, and lower minimum cur-

rent draw from the phone line.

- Is a single-chip solution

Applications

• Computer telephony and gateways, such as VoIP

• PBXs

Ordering Information

• Satellite and cable set-top boxes

• V.92 (and other standard) modems

• Fax machines
