... IrDA Infrared Communication Module RPM873 RPM873 is an infrared communication module for IrDA Ver. 1.2 (Low Power). The infrared LED, PIN photo diode, and 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 ...

... Caution in designing board lay-out To get maximum potential from RPM873, please keep in mind following instruction. •The line of RXD (6pin) should be connected at backside via through hole close to RPM873 pin lead. Better not to be close to photo diode side (1pin). ⇒This is to minimize feedback supplied to photo diode from RXD. ...
