Note:

1) Maximum value is given by eye safety class 1, IEC 60825-1, simplified method.

2) Due to this wavelength restriction compared to the IrDA spec of 850 nm to 900 nm the transmitter is able to operate as source for the

standard Remote Control applications with codes as e.g. Philips RC5/RC6® or RECS 80. When operated under IrDA full range

conditions (125 mW/sr) the RC range to be covered is in the range from 8 m to 12 m, provided that state of the art remote control

receivers are used.
