Note:
All timing data measured with 4 Mbit/s are measured using the IrDA^® FIR transmission header. The data given here are valid 5 µs after
starting the preamble.
1) This parameter reflects the backlight test of the IrDA physical layer specification to guarantee immunity against light from fluorescent
lamps
2) IrDA sensitivity definition: Minimum Irradiance E_e In Angular Range, power per unit area. The receiver must meet the BER
specification while the source is operating at the minimum intensity in angular range into the minimum half-angle range at the maximum
Link Length
3) 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).
4) Retriggering once during applied optical pulse may occur
