Infrared Transceiver Technical Data HSDL-1100 Features • Fully Compliant to IrDA 1.1 – 4 Mbps • Compatible with ASK, HPSIR, and TV Remote • Backward Compatible to Slower Speeds • Excellent Nose to Nose Operation • Excellent Noise Immunity • No Programming to Switch Speeds • Available in Several Mounting Options • Designed to Compensate for Light Loss Due to Cosmetic Windows • Fully Supported by All Interface Chips 115.2 Kb/s and RXD-B for signal rates of 576 Kb/s and 4.0 Mb/s. The receiver is designed for maximum sensitivity to IrDA signals and minimum sensitivity to signals outside the IrDA optical wavelength and frequency modulation of interest. A receiver lens magnifies the effective area of the PIN diode to enhance sensitivity. The lens is integral with the molded package and contains a dye which absorbs visible light. Receiver outputs pulse low when the IR signal is present. The power supply for the PIN and preamplifier are filtered to attenuate noise conducted from external sources. VCC Application Circuit Description The HSDL-1100 infrared transceiver provides the interface between logic and IR signals for through-air, serial, half-duplex IR data links and is designed to satisfy the IrDA Physical Layer Specification. The HSDL-1100 contains a high speed, high efficiency, TS AlGaAs 870 nm LED, a silicon PIN photodiode, and a bipolar, silicon integrated circuit. The IC contains an LED driver and a receiver providing two output signals, RXD-A for signal rates from 2.4 to Applications for the HSDL-1100 include notebook PCs, LANs, telephones, pagers, printers, cameras, and industrial handheld devices.

LED Drive Current vs. Case Temperature 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/cm2 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. www.hp.com/go/ir For technical assistance or the location of your nearest Hewlett-Packard sales office, distributor or representative call: Americas/Canada: 1-800-235-0312 or 408-654-8675 Far East/Australasia: Call your local HP sales office.
