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 Family
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.
Features:
• Voice and data applications
• Modem DAA for speeds up to V.92
• Half-wave or full-wave ring detection
• Worldwide telephone network compatibility
• Caller-ID reception
• Line side powered from telephone line
• 3.3 or 5V power supply
• Easy interface with modem ICs and voice CODECs
• High power transmit option

Applications:
• Computer telephony
• VoIP gateways
• PBXs
• Satelite set-top box
• V.92 modems
• Fax machines
• Voice mail systems
• Embedded modems
• Vending Machines
• Automated banking
• Remote metering
• Surveillance
• Security systems
