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
