Duty : LED duty at emitting
Please set up to be ILED < 250 [mA] (Duty 25%)
(Reference) In case of using R1, typical intensity (Ieltyp) and maximum intensity (Ielmax) on axis are described as below. Ieltyp = 260 x (VLEDVCC-1.31) / (R1+5.8) Ielmax = 615 x (VLEDVCC-1.31) / (R1+5.8)

Notes 1) LEDVCC (1pin), VCC (5pin) * Other power source can be used difference between LEDVCC and VCC. 2) Caution in designing board lay-out To get maximum potential from RPM922-H11, please keep in mind following instruction. * The line of RXD (3pin) should be connected at backside via through hole close to RPM922-H11 pin lead. Better not to be close to photo diode side (6pin 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 (6pin side) and also away from the parts which generate noise, such as DC / DC converter. * As for C1 between 5-6 pins, it should be placed close to RPM922-H11. 3) Notes * Please be sure to set up the TXD (2pin) input to be "L" (under 0.3V) except transmitting data. (For < 90 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. * Dusts or scratch on the lens may effect the characteristics of product, Please handle it with care. 4) Eye safe * EN60825-1 (IEC60825-1 amendment2), Class1 Eye safe.
