(4) High level, low level output voltage When standard transmitter output the signal at Fig.1 standard photodiode output become io = 5µ AP-P under the measurement condition Fig2, Fig.3. www.DataSheet4U.com RPM-301B: standard photodiode has short current ISC = 27µ A at E = 10001x (using CIE standard light source A) 556 www.DataSheet4U.com Communication ICs FMeasurement circuit RPM6900 Series FRecommended application S Please place filter (resistors and capacitors) as close to the receiver as possible. S In order to stable operation, using serial resistor (47Ω) on power supply line and capacitor (more than 47µF) between power supply and GND is recommended. (This reduce influence by switching power supply ripple and ripple which caused by the change of micro controller load and other circuits load.) Without the above circuit, Arrival distance might be less due to noise pulse on output wave. (In case even with the above mentioned value, please change bigger capacitance.) FOperation notes (1) All characteristics of the receiver in this specification are specified by supplying burst wave form with ROHM standard transmitter (Fig.2). If in case of other burst wave form will be used, please check these spec. Carefully under the evaluations. (2) When the receiver will be used as the wire-less remote controller, please use the signal method the signal formatwww.DataSheet4U.com which refer to “Measures to prevent miss-functioning of IR remote-controlled electric home appliances”. (Published July 1987 by Association of Electric Home Appliances) However, please use the standard pulse width (T) of greater than 0.4ms and less than 0.6ms (0.4ms < T < 0.6ms) If using other signal method, signal format, (ex: signal format which not including the leader signal) the receiver might have chances to miss-function. 557 www.DataSheet4U.com .
