Low Cost PSTN Interface
Pb • A highly featured PSTN Interface (COIC,
FXO, DAA, Trunk Interface) in a single
12mm high SIL device.
• +5V or +3.3V supply.
• Transformer isolation providing high
common-mode rejection (CMRR) for use in
• Highly integrated with on-board loop switch
and diode bridge.
• Loop start circuit, ringing detect, line
detection and parallel phone detect.
• Approved to:
IEC60950-1: First Edition 2001
UL60950-1: 2003 1st Edition
CSA 22.2 No.60950-1-03 1st Edition
• On-hook reception.
• Meets requirements of FCC Pt68.
Low cost power cross protection.
• Programmable d.c. mask, line and network
impedances, allows use in any market.
• Silvertel “design-in” assistance.
The Ag2130 is a self-contained highly
integrated PSTN Interface Circuit in a single
SIL module, which complies with ROHS
In addition to the features listed, the Ag2130
allows flexible programming of many functions,
including the dc voltage mask and
impedances. The Ag2130 meets international
safety and regulatory requirements.
The device requires a minimum of external
components and has been specified for ease
of use, to allow reduced time to market.
The Ag2130 is designed for all applications,
including those where there is a high level of
common mode interference, such as PABX,
long loop applications and systems without a
