Description
Clare CPC5610 and CPC5611 LITELINKs are silicon
data access arrangement (DAA) ICs used in data and
voice communication applications to make connec-
tions to the public switched telephone network
(PSTN). LITELINK uses on-chip optical components
and a few inexpensive external components to form a
complete voice or high-speed data telephone line
interface.
LITELINK eliminates the need for the large isolation
transformers or capacitors as used in other DAA con-
figurations. It incorporates the required high-voltage
isolation barrier in the surface-mount SOIC package.
The CPC5610 (half-wave ring detect) and CPC5611
(full-wave ring detect) build upon Clare’s existing
LITELINK line, with improved performance and 3.3 V
operation.
