Electrical & Optical Specifications
Specifications hold over the Recommended Operating Conditions unless otherwise noted. Unspecified test condi-
tions can be anywhere in their operating range. All typical values are at 25˚C and 3.3 V unless otherwise noted.

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.

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/cm

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.
