Notes:
4. An in-band optical signal is a pulse/sequence where the peak wavelength, l
5. For in-band signals 9.6 kbit/s to 115.2 kbit/s where 9 µW/cm
6. Latency is defined as the time from the last TxD_IrDA light output pulse until the receiver has recovered full sensitivity.
7. Receiver Wake Up Time is measured from V
8. Transmitter Wake Up Time is measured from V
9. The Optical PW is defined as the maximum time in which the IR LED will turn on. This is to prevent the long Turn On time for the IR LED.
