DESCRIPTION
The IC ASK-modulation is also possible. Only an external PIN-photodiode and an infrared emitting diode with current limiting resistor must be connected to the corresponding pins. Two different sensitivity modes, which can be programmed by applying a “High” or “Low” voltage at pin SC, ensure either an increase in transmission distance or a bit error rate of 1E-9. An internal AGC allows proper operation under EMI conditions. FEATURES
