Notes:
8. An in-band optical signal is a pulse/sequence where the peak wavelength, p, is defined as 850
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 W/cm
11. For in-band signals at 1.15 Mb/s where 9.0 W/cm
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
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

2 s 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 W/cm
