rx th+ (receiver on- threshold) the maximum receiver on- threshold 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 m w/cm 2 , 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 incandes- cent 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 v ol (rxd) specification guarantees a maximum receiver on-threshold of ei = 3.6 m w/cm 2 , at a ber 10 -9 , and t a = 0-70 c. the ei = 3.6 m w/cm 2 threshold guarantees the irda minimum receiver sensitivity of 4.0 m w/cm 2 , while allowing for 10% light loss through a cosmetic window placed in front of the hsdl-1000. the ei = 3.6 m w/cm 2 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. note: at the time of this publication, light emitting diodes (leds) that are contained in this product are regulated for eye safety in europe by the commission for european electrotechnical standardization (cenelec) en60825-1. please refer to application brief i-008 for more information. 10
