AG2120 Overview
The Ag2120 is a self-contained highly integrated PSTN Interface Circuit in a single SIL or DIL Module.
AG2120 Key Features
- A highly featured PSTN Interface (COIC, FXO, DAA, Trunk Interface) in a single DIL or 12mm high SIL device
- +5V or +3.3V supply
- Transformer isolation providing high mon mode rejection (CMRR) for use in un-grounded systems
- Highly integrated with on board loop switch and integral diode bridge
- Loop start circuit, ringing detect and loop current detection. Parallel phone detect
- Tip-ring polarity reversal detect (for Caller Line ID and remote metering) and on-hook reception
- Meets requirements of EN60950/UL1950, and FCC Pt68. Low cost power cross protection
- Programmable d.c. mask, line and network impedances
- Silver Tele “design-in” assistance
