LITELINK III Phone Line Interface IC (DAA)

• Embedded modems for POS terminals, automated

banking, remote metering, vending machines,

security, and surveillance

Features

• Superior voice solution with low noise and excellent

part-to-part gain accuracy

• 3 kV

line isolation

RMS

Description

• Simultaneous ringing detection and CID monitoring

for worldwide applications

• Provides both full-wave ringing detect and half-wave

ringing detect for maximum versatility

• Transmit power of up to +10 dBm into 600 Ω

• Data access arrangement (DAA) solution for modem

speeds up to V.92

LITELINK III is a single-package silicon phone line

interface (PLI) DAA used in voice and data

communication applications to make connections

between host equipment and telephone networks.

LITELINK uses on-chip optical components and a few

inexpensive external components to form the required

high voltage isolation barrier. LITELINK eliminates the

need for large isolation transformers or capacitors

used in other phone line interface configurations.

• 3.3V or 5 V power supply operation

• Easy interface with modem ICs and voice CODECs

• Worldwide dial-up telephone network compatibility

• CPC5622 can be used in circuits that comply with

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

UL60950 (UL1950), EN60950, IEC60950,

EN55022B, CISPR22B, EN55024, and TBR-21

• Line-side circuit powered from telephone line

• Compared to other silicon DAA solutions, LITELINK:

- Uses fewer passive components

LITELINK also provides AC and DC phone line

terminations, switchhook, 2-wire to 4-wire hybrid,

ringing detection, and full time receive on-hook

transmission capability.

The CPC5622 is a member of and builds upon Clare’s

third generation of LITELINK products with improved

insertion loss performance and lower minimum current

draw from the phone line. The CPC5622 version of

LITELINK III provides concurrent ringing detection and

CID monitoring for world wide applications. Both

half-wave and full-wave ringing detection are provided

for maximum versatility.

- Takes up less printed-circuit board space

- Uses less telephone line power

- Is a single-IC solution

Applications

• Computer telephony and gateways, such as VoIP

• PBXs

• Satellite and cable set-top boxes

• V.92 (and other standard) modems

• Fax machines
