2. 50% duty cycle, max pulse width 165 s (3/16 of (1/1200 bps + 5%)).
4. The 30% tolerance covers chip-to-chip variation. The temperature coefficient of the receiver
5. Turn-around time is the time taken for the PIN diode receiver to recover from the IR energy
6. This is a system specification. A metal shield over the PIN diode and CS8130 is
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.
