Silvertel Telecom Interface Modules offer a small range of analog interface modules that are small and easy to use. These modules are available in a Single In-Line (SIL) or Dual In-Line (DIL) packages. The telecom interface modules come in single Subscriber Line Interface Circuit (SLIC) module and Public Switched Telephone Network (PSTN) module variants.
The SLIC modules feature very simple integration and 600R impedance. These modules include on-board ringing generators on few modules, while few modules include short circuit protection.
The PSTN modules feature transformer isolation and the PSTN interface and ringing detection. These modules include onboard loop switch, diode bridge, and parallel phone detection. The PSTN modules operate at 3.3V or 5V input voltage.
