Notes:
8. An in-band optical signal is a pulse/sequence where the peak wavelength, λp, is defined as 850 ≤ λp ≤ 900 nm, and the pulse characteristics
are compliant with the IrDA Serial Infrared Physical Layer Link Specification.
9. Logic Low is a pulsed response. The condition is maintained for duration dependent on pattern and strength of the incident intensity.
10. For in-band signals ≤ 115.2 kb/s where 3.6 µW/cm2 ≤ EI ≤ 500 mW/cm2.
11. For in-band signals at 1.15 Mb/s where 9.0 µW/cm2 ≤ EI ≤ 500 mW/cm2.
12. For in-band signals of 125 ns pulse width, 4 Mb/s, 4 PPM at recommended 400 mA drive current.
13. Pulse width specified is the pulse width of the second 500 kHz carrier pulse received in a data bit. The first 500 kHz carrier pulse may exceed
2 µs in width, which will not affect correct demodulation of the data stream. An ASK or DASK system using the HSDL-3602 has been shown to
correctly receive all data bits for 9 µW/cm2 ≤ EI ≤ 500 mW/cm2 incoming signal strength. ASK or DASK should use the FIR channel enabled.
14. The wake up time is the time between the transition from a shutdown state to an active state, and the time when the receiver is active and
ready to receive infrared signals.
