IrDA Infrared Communication Module
RPM972-H14
RPM972-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.
Also it provides the capability of IR remote control transmission for universal remote control applications.
zFeatures
1) Infrared LED, PIN photo diode, LED driver and receiver frequency formation circuit built in.
Improvement of EMI noise protection by Shield Case.
2) Applied to SIR (9.6k to 115.2kbps), MIR (0.576M, 1.152Mbps) and FIR(4Mbps).
3) Surface mount type.
4) Power down function built in.
5) Adjustable communication distance by LED load resistance value.
6) Infrared remote control transmission driver built-in.
zApplications
Cellular phone, PDA, DVC, Digital still camera, Printer, Handy terminal etc.
