... IrDA Infrared Communication Module RPM971-H14 RPM971-H14 is an infrared communication module for IrDA Ver. 1.4 (Low Power). The infrared LED, PIN photo diode, and waveform shaping LSI are all integrated into one single package. This module is designed for low power consumption. The very small package makes it a perfect fit for mobile devices. ...

... To get maximum potential from RPM971-H14, please keep in mind following instruction. • The line of RXD (4pin) should be connected at backside via through hole close to RPM971-H14 pin lead. Better not to be close to photo diode side (8pin side). ⇒This is to minimize feedback supplied to photo diode from RXD. ...
