This parameter reflects the backlight test of the IrDA physical layer specification to guarantee immunity against light from fluorescent lamps.
IrDA sensitivity definition: minimum irradiance E
the source is operating at the minimum intensity in angular range into the minimum half-angular range at the maximum link length.
Maximum irradiance E
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) specification. For more definitions
see the document “Symbols and Terminology” on the Vishay website
RXD output is edge triggered by the rising edge of the optical input signal. The output pulse duration is independent of the input pulse duration.
The radiant intensity can be adjusted by the external current limiting resistor to adapt the intensity to the desired value. The given value is for
minimum current consumption. This transceiver can be adapted to > 50 cm operation by increasing the current to > 200 mA, e.g. operating
the transceiver without current control resistor (i.e. R1 = 0 Ω) and using the internal current control.
