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. IXYS Integrated Circuits Division 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.

LITELINK III Evaluation Board
The CPC5622-EVAL-600R evaluation board ships with the CPC5622 LITELINK III and CPC5712 voltage monitor to demonstrate the functionality of a PSTN two-wire terminating interface that provides both the analog voice transmission and signaling functions. The analog interface is configured to provide a 600 Ohm resistive AC impedance with 0dB gain in both the transmit and receive directions. While the CPC5622 provides the hook switch and ringing detect signaling functions, the CPC5712 is utilized to monitor and detect changes in the DC line voltage to determine loop status and signaling information sent by the network. Status of the loop is given by the logic level outputs of the three CPC5712 on-board detectors indicating Loop Presence, Line In Use, and Loop Polarity.
