testing. 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.
IrDA latency definition: receiver latency allowance (milliseconds or microseconds) is the maximum time after a node ceases transmitting
before the node’s receiver recovers its specified sensitivity. During this period and also during the receiver start up time (after power on or
shutdown) the RXD output may be in an undefined state.
IrDA sensitivity definition: minimum irradiance Ee 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.
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.
