Notes: 5. Typical PIN diode junction capacitance is 70 pF.
6. The temperature coefficient of the receiver threshold setting is low. Current detection thresholds are
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.
7. Turn-around time is the time taken for the PIN diode receiver to recover from the IR energy from the
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.
