Notes:
3. Typical PIN diode junction capacitance is 50pF.
4. The
±30% tolerance covers chip-to-chip variation. 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.
5. Turn-around time is the time taken for the PIN diode receiver to recover from the IR energy
from the 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 from
the transmit LED to the PIN diode.
6. This is a system specification. A metal shield over the PIN diode and CS8130 is
recommended to ensure system compliance.
