Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
Note: All timing data measured with 4 Mbit/s are measured using the IrDA
after starting the preamble.
*)
mitting before the node’s receiver recovers its specified sensitivity. During this period and also during the receiver start up time (after power
on or shut down) the RXD output may be in an undefined state.

Length
***)
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) specifica-
tion.
