Silicon Data Access Arrangements (DAA), Phone Line Interface Telephone Network Interfaces Connecting to telephone networks for both voice and data applications requires a suitable interface that offers all of the required functionality and that is compatible with the network. Clare offers two types of data access arrangement solutions, LITELINK™ and Cybergate™. LITELINK is a single-IC high-speed, low cost phone line interface (DAA) solution. Cybergate offers faster integration for lower-speed applications.
LITELINK single-chip Silicon phone line interfaces (DAA) use optical technology to include the required isolation barrier in the package, eliminating high cost capacitors or transformers.This solution saves cost relative to competitive solutions through reduced passive component count and smaller printed-circuit board space.LITELINK supports differential and single-end receive and transmit ports providing an easy interface to popular modem ICs codecs and voice SLAC devices.
