4 / 7 page RPM7200-Hx series Photo Link Module 4/6 (4) Output signal 600 µs TON TOFF VCC GND 1/2 VCC VH VL 600 µs Fig.4 Carrier frequency=f0 Carrier Duty=50% Transmit signal Output signal (5) Measurement circuit for the output voltage and the consumption current Fig.5 VCC VH , VL VCC ICC ROUT GND A V RPM7200-Hx ! ! ! ! Notes (1) All characteristics of the receiver in this specification are specified by supplying burst wave form (Fig.1) 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 format which refer to “Measures to prevent mulfunctioning of IR remote-controlled electric home appliances”. (Published July 1987 by Association of Electric Home Appliances) If using other signal method, signal format, (ex: signal format which not including the leader signal) the receiver might have chances to miss-function. (3) Please set up transmitter’s carrier frequency as same as the receiver’s f0 frequency. Otherwise error might be occurred. (4) If transmission signal has non-continues carrier, error might be occurred. Continuous carrier is necessary. |
