Notes :
8. An in-band optical signal is a pulse/sequence where the peak wavelength,
λ
p, is defined as 850
λ
p
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.

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
μ
s in width, which will not affect correct demodulation of the data stream. An ASK or DASK system using the
HSDL-3600 has been shown to correctly receive all data bits for 9

incoming signal strength. ASK
or DASK should use the FIR channel enabled.
14. 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.
15. Shields to be grounded.
