6. The temperature coefficient of the receiver threshold setting is low. Current detection thresholds are
7. Turn-around time is the time taken for the PIN diode receiver to recover from the IR energy from the
above the DC ambient condition. Settings of RS4-0 of less than 00010 are not practical because of
noise. RX threshold settings are roughly linear following the formula:
Threshold (nA) = (RX setting + 1) * 20 + 36.
local transmitter. The remote end of the link must wait for this time after receiving data before
transmitting a reply. This time may be reduced to <1 ms by good IR shielding between the transmit LED
to the PIN diode.
