Notes
1) LEDVCC (8pin) and VCC (3pin)
"
Other power source can be used difference between LEDVCC and VCC.
2) Caution in designing board lay-out
To get maximum potential from RPM870-H14, please keep in mind following instruction.
"
The line of RXD (6pin) should be connected at backside via through hole close to RPM870-H14 pin lead. Better not
to be close to photo diode side (1pin).
襎his is to minimize feedback supplied to photo diode from RXD.
"
As for C1 between 3-4 pin should be placed close to RPM870-H14.
"
Better to be placed more than 1.0cm in radius from photo diode (pin1 side) and also away from the parts which
generates noise, such as DC / DC converter.
3) Others
"
Please be sure to set up the TXD (7pin) input to be L (under 0.5V) except transmitting data
(for < 90祍ec. on duty < 20%).
"
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 Ver1.2 (Low Power). There might be on error if used by
different signal format.
"
Please pay attention to the lens carefully. Dusts of scratch on the lens may effect the characteristics of product. Please
handle it with care.
4) Eye Safe
"
IEC825-1 (EN60825-1) Class 1 Eye Safe.
