PLL_IR_LASER_LIGHT_RECEIVER

Published:2009/6/22 22:29:00 Author:May | From:SeekIC

Circuit schematics for the 555-based PLL laser light PFM receiver. Although R4 is shown as a resistor, you might want to sub-stitute it with a 10-kΩ precision potentiometer so that you can dial in the center frequency of the transmitter. Experiment with the value of C1 for the best high-frequency response. Notice that circuit is functionally identical to the laser light detector/receiver shown in the figure, but with the addition of the 565.
