IrDA Infrared Communication Module

RPM841-H11

RPM841-H1 1 is an infrared communication module for IrDA V er. 1.2 (Low Power). The infrared LED, PIN photo diode, LSI are all integrated into a single package. This module is designed with power dow n function and low current consumption at stand-by mode. The ultra small package makes it a perfect fit for mobile devices.
zFeatures
1) Infrared LED, PIN photo diode, LED driv er & Receiv er freq uency form ation circ uit built in. Impr ovement of EMI noise protection because of Shield Case.
2) Applied to SIR (2.4 to 115.2kbps)
3) Surface mount type.
4) Power down function built in.
5) Super small package (W=6.8mm, D=2.44mm, H=1.5mm).
6) Infrared remote control transmission driver built-in.
