DescriptionLITELINK III CPC5620 is a single-package silicon phone line interface/DAA used in voice and data communication applications to make connections between host equipment and telephone networks.
LITELINK CPC5620 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.
LITELINK CPC5620 uses on-chip optical components and a few inexpensive external components to form a complete voice or high-speed data phone line interface.
LITELINK CPC5620 eliminates the need for the large isolation transformers or capacitors used in other interface configurations. It incorporates the required high-voltage isolation barrier in the surface-mount SOIC package.
The CPC5620 (half-wave ring detect) and CPC5621 (full-wave ring detect) PLIs build upon Clare's
LITELINK II line, CPC5620 with improved insertion loss control, improved noise performance, and lower minimum current draw from the phone line.
