Notes:

1. An in-band optical signal is a pulse/sequence where the peak wavelength,

λp, is defined as 850 nm ≤ λp ≤ 900 nm, and the pulse characteristics

are compliant with the IrDA Serial Infrared Physical Layer Link Specification.

2. For in-band signals 2.4 kbps to 115.2 kbps where 3.6

3. Latency is defined as the time from the last TXD light output pulse until the receiver has recovered full sensitivity.

6. Maximum optical pulse width is defined as the maximum time that the LED will remain on. This is to prevent the long turn on time for the LED.
