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-H14, please keep in mind following instruction.
•
The line of RXD (4pin) should be connected at backside via through hole close to RPM960-H14 pin lead. Better not
to be close to photo diode side (8pin side).
⇒This is to minimize feedback supplied to photo diode from RXD.
•
Better to be placed at more than 1.0cm radius from photo diode (8pin side) and also away from the parts which
generate noise, such as DC / DC converter.
•
As for C1 between 6 and 8 pins, it should be placed close to RPM960-H14.
3) Notes
•
Please be sure to set up the TXD (3pin) input to be “L” (under 0.6V) except transmitting data.
(For < 90µ sec. 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.
4) Eye safe
