info

LITELINK™ single-chip Silicon phone line interfaces (DAA) use optical technology to include the required isolation barrier in the package, eliminating costly 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.
