RPM841-H16
Photo Link Module
Rev.B
8/9
Attached components
Recommended values
Part symbol
C1
Recommended value
Notice
1礔, tantalum or ceramic
Ex.) TCFGA1A105M8R (ROHM)
Bigger capacitance is recommended with much noise from power supply
R1
2.2&?%, 1/8W
(VLEDVCC=3V)
At LED Emitting Duty=25%
[LED current set-up method for Remote control mode]
In case of using R1 with different condition from the above, formula is as follows :
LED resistance value : R1[&], LED average consumption current : ILED[mA], Supply voltage : VLEDVCC[V],
minimum necessary of irradiant intensity le1 [mW / sr]
(Including LEDs distribution within ?5deg)
R1=166 ?(VLEDVCC1.31) / le17.2
ILED=Duty ?(VLEDVCC1.31) / (R1+5.8)
Duty : LED duty at emitting
Please set up to be ILED / Duty < 250[mA] (Duty d 25%)
At IrDA Mode, LED current is constantly approximately 50mA.
(Reference) In case of using R1, typical intensity (le1typ) and maximum intensity (le1max) on
axis are described as below.
le1typ=280 ?(VLEDVCC1.31) / (R1+5.8)
le1max=560 ?(VLEDVCC1.31) / (R1+5.8)
Notes
1) LEDVCC (1pin), VCC (6pin)
"
Other power source can be used difference between LEDVCC and VCC.
2) Caution in designing board lay-out
To get maximum potential from RPM841-H16, please keep in mind following instruction.
"
The line of RXD (4pin) should be connected at backside via through hole close to RPM841-H16 pin lead. Better not to
be close to photo diode side (7pin).
襎his is to minimize feedback supplied to photo diode from RXD.
"
As for C1 between 6-7 pin should be placed close to RPM841-H16.
"
Better to be placed more than 1.0cm in radius from photo diode (pin7 side) and also away from the parts which
generates noise, such as DC / DC converter.
3) Notes
"
Please be sure to set up the TX-RC (2pin) and the TXD (3pin) input to be L (under 0.3V) except transmitting data
(for < 90祍, ON duty d 50%).
"
Power down current might increase if exposed by strong light (ex. direct sunlight) at powerdown mode.
"
Please use by the signal format at IrDA operating mode which is specified by IrDA Ver1.2 (2.4k to 115.2kbps). 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.
