Notes
1 Sine wave reference: The SWG10 can amplify any sinusoidal reference signal with a frequency between 15Hz and 60Hz. Thus standard telecom ringer frequencies, such as 15Hz, 25Hz and 50Hz can be easily output. A sinewave reference needs to be coupled to the unit with a single 0.1F to 1F (100V) capacitor. Efficiency measured with resistive load, Output voltage range adjust: the output voltage is proportional to the reference sinewave at Ref-In pin (after external coupling capacitor). The ringer has a voltage gain of 30.8 (typ.). Remote ON/OFF: The remote shutdown operates on. Open collector sink of 1mA to shut off. The operating temperature range assumes that sufficient airflow exists to ensure the case/encapsulation temperature never exceeds +85oC. At any power up, the case temperature should not exceed +70oC. The input and output fuses are essential because there is no internal short circuit or overcurrent protection circuitry. System design should ensure that multiple `receiver lifts' (modems, faxes, answering machines) do not occur simultaneously to cause peak output current to exceed the 400mA, 150ms maximum. System design should ensure that `Sine Wave Reference' pin 2 is set such that Vout never exceeds 80V.
