Photo Link Module
IrDA Infrared Communication Module
RPM841-H16
RPM841-H16 is an infrared communication module for IrDA Ver. 1.2 (Low Power). The infrared LED, PIN photo diode,
LSI are all integrated into a single package. This module is designed with power down function and low current
consumption at stand-by mode. The ultra small package makes it a perfect fit for mobile devices.
1) Infrared LED, PIN photo diode, LED driver & Receiver frequency formation circuit built in. Improvement of EMI noise
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=1.7mm, H=2.28mm).
6) Infrared remote control transmission driver built-in.
Mobile phone, PDA, DVC, Digital Still Camera, Printer, Handy Terminal etc.
