Note:
[9] An in-band optical signal is a pulse/sequence where the peak wavelength, O
[10] For in-band signals 115.2 kbit/s where 9 PW/cm2 ≤ EI ≤ 500 mW/cm2.
[11] For in-band signals 1.152 Mbit/s where 22 PW/cm2 ≤ EI ≤ 500 mW/cm2.
[12] Latency is de ned as the time from the last TxD light output pulse until the receiver has recovered full sensitivity.
[13] Receiver Wake Up Time is measured from Vcc power ON to valid RxD output.
[14] Transmitter Wake Up Time is measured from Vcc power ON to valid light output in response to a TxD pulse.
[15] The Max Optical PW is de ned as the maximum time which the IR LED will turn on, this, is to prevent the long Turn On time for the IR LED.
