Notes:

1. Pulsed Response — Logic Low is a pulsed response. A receiver output low state VOL(RXD) is not indefinitely maintained but is instead a pulsed response. The output low state is maintained for a duration dependent on the incident bit pattern and incident intensity (EI).

2. The EI ≥ 3.6 µW/cm2 condition guarantees the IrDA minimum receiver sensitivity of 4.0 µW/cm2 while allowing for 10% light loss through a cosmetic window placed in front of the HSDL-1001.

Appendix A. Test Methods

A.1. Background Light and Electromagnetic Field

There are four ambient interference conditions in which the receiver is to operate correctly. The conditions are to be applied separately:

1. Electromagnetic field: 3 V/m

maximum (refer to IEC 801-3. severity level 3 for details)

2. Sunlight: 10 kilolux maximum

at the optical port

This is simulated with an IR source having a peak wavelength within the range 850 nm to 900 nm and a spectral width less than 50 nm biased to provide 490 µW/cm2 (with no modulation) at the optical port. The light source faces the optical port.

This simulates sunlight within the IrDA spectral range. The effect of longer wavelength radiation is covered by the incandescent condition.

3. Incandescent Lighting: 1000 lux maximum

This is produced with general service, tungsten-filament, gasfilled, inside-frosted lamps in the 60 Watt to 150 Watt range to generate 1000 lux over the horizontal surface on which the equipment under test rests. The light sources are above the test area. The source is expected to have a filament temperature in the 2700 to 3050 degrees Kelvin range and a spectral peak in the 850 nm to 1050 nm range.

4. Fluorescent Lighting: 1000 lux maximum

This is simulated with an IR source having a peak wavelength within the range 850 nm to 900 nm and a spectral width of less than 50 nm biased and modulated to provide an optical square wave signal (0 µW/cm

minimum and 0.3 µW/cm2 peak amplitude with 10% to 90% rise and fall times less than or equal to 100 ns) over the horizontal surface on which the equipment under test rests. The light sources are above the test area. The frequency of the optical signal is swept over the frequency range from 20 kHz to 200 kHz.

Due to the variety of fluorescent lamps and the range of IR emissions, this condition is not expected to cover all circumstances. It will provide a common floor for IrDA operation.
