Rev.C 4/5 RPM960-H14 Photo Link Module Notes 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 • EN60825-1 (IEC60825-1 amendment2), Class1 Eye safe.
