banking, remote metering, vending machines,
security, and surveillance
Description
LITELINK III is a single-package silicon phone line
interface (PLI) DAA used in voice and data
communication applications to make connections
between low-voltage equipment and high-voltage
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.
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.
