**) IrDA sensitivity definition: Minimum Irradiance Ee In Angular Range, power per unit area. The receiver must meet the BER specifica-
tion while the source is operating at the minimum intensity in angular range into the minimum half-angle range at the maximum Link Length.
***) Maximum Irradiance Ee In Angular Range, power per unit area. The optical delivered to the detector by a source operating at the
maximum intensity in angular range at Minimum Link Length must not cause receiver overdrive distortion and possible related link errors.
If placed at the Active Output Interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER).
For more definitions see the document “Symbols and Terminology” on the Vishay Website (http://www.vishay.com/docs/82512/82512.pdf).
