IrDA Infrared Communication Module
RPM960-H7
RPM960-H7 is an infrared communication module for IrDA Ver. 1.3 (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.
zFeatures
1) Infrared LED, PIN photo diode, LED driver & Receiver frequency formation circuit built in.
Improvement of EMI noise protection because of Shield Case.
2) Applied to SIR (2.4 k to 115.2 kbps) and MIR (0.576,1.152 Mbps)
3) Surface mount type.
4) Power down function built in.
5) Adjustable communication distance by LED load resistance value.
zApplications
Cellular Phone, PDA, DVC, Digital Still Camera, Printer, Handy Terminal, etc

∗1) This applies to all pins basis ground pin (8pin).
∗2) LED Peak Current : <90 µs, On duty <25%
∗3) When glass-epoxy board (70x70x1.6mm) mounted. In case of operating environment is over 25˚C, 4mW
would be reduced per each 1˚C stepping up.

zNotes
1) LEDVCC (1pin), VCC (6pin) and VIO (7pin)
• Other power source can be used difference between LEDVCC and VCC and VIO. (VIO < VCC +0.3V)
2) Caution in designing board lay-out
To get maximum potential from RPM960-H7, please keep in mind following instruction.
• The line of RXD (4pin) should be connected at backside via through hole close to RPM960-H7 pin lead. Better not
to be close to photo diode side (8pin side).
⇒This is to minimize feedback supplied to photo diode from RXD.
• As for C1 between 6-8 pin should be placed close to RPM960-H7.
• Better to be placed more than 1.0cm in radius from photo diode (8pin side) and also away from the parts which
generates noise, such as DC / DC converter.
3) Notes
• Please be sure to set up the TXD (3pin) input to be “L” (under 0.6V) except transmitting data
(for < 90µsec. On Duty < 25%).
• Powerdown current might increase if exposed by strong light (ex. direct sunlight) at powerdown mode.
• Please use by the signal format which is specified by IrDA Ver1.3 (Low Power) except 4 Mbps.
There might be on error if used by different signal format.
• Dust or dirt on lens portion may affect the characteristics, so pay suffye Safe
• IEC825-1 (EN60825-1) Class 1 Eye Safe.
