Receiver Output Pulse Width vs. Duty Cycle of Received Signal. 10 Rx TH+ (Receiver OnThreshold) The maximum receiver onthreshold is equivalent to the minimum receiver sensitivity. Both are terms for the amount of light signal which must be present at the HSDL-1000 detector in order to trigger a low pulse on the receiver output (RXD). The IrDA Physical Layer Specification requires a minimum receiver sensitivity of 4.0 µW/cm2, at a Bit Error Rate of 10-9, and in the presence of the 10 klux of sunlight, 0-1000 lux of fluorescent light, or 0-1000 lux of incandescent light. The fluorescent and incandescent specifications require minimum receiver sensitivity with 1000 lux incident onto the horizontal surface of the IR link. The resulting amount of fluorescent or incandescent light actually reaching the detector surface may vary between 0 and 500 lux depending upon the design of the housing around the HSDL-1000 module. The HSDL-1000 VOL(RXD) specification guarantees a maximum receiver on-threshold of EI = 3.6 µW/cm2, at a BER ≤ 10-9, and TA = 0-70°C. The EI = 3.6 µW/cm2 threshold 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-1000. The EI = 3.6 µW/cm2 threshold also guarantees receiver sensitivity with 10 klux of sunlight, 0-500 lux fluorescent light, or 0-500 lux of incandescent light incident on the HSDL-1000 detector surface.
