Overview

Ag2120 is a highly integrated trunk or PSTN/COIC interface, available in either a DIL or SIL package. The module boasts many integrated features, including a basic barrier on-chip and programmable DC mask. The Ag2120 can be used in systems without a ground, or in applications where common mode interference is very high. It can also be operated from either a +3.3V or a +5V supply.


Features

  • Highly featured PSTN interface

  • Very small SIL and DIL package options

  • Includes Transformer isolation

  • On board Loop switch and Diode bridge

  • Ringing and loop current detection

  • Parallel phone detect

  • Programmable to meet different country standards

  • Tip/Ring polarity detect for CLI and on hook reception

  • 3.3V or 5V input
