technical data preliminary data 1 GP1H20 irda 1.0 / irda 1.2 low power technical data compliant compact feature type 1. features a irda 1.2 low power option compliant (i f = 27 ma at reception distance of 20 cm) a industry smallest package design for irda 1.0 compliant infrared transceiver (w 8.7 x d 4.2 x h 3.15 mm) a suitable and fits in the mobile phone connector dimensions a low power consumption by built-in shut-down mode (max. 1 ma) a wide range operating voltage provide power line design flexibility (v cc = 2.7v ~ 5.5v) a soldering reflow capability for automated production process a smd package enables both vertical mount and horizontal mount to pcbs 2. description the sharp GP1H20, low operating smallest irda 1.0 compliant infrared transceiver module, provides the interface between logic and ir signals for through-air, serial, half-duplex ir wireless data links and is designed to satisfy the irda physical layer specifications. the sharp GP1H20 infrared transceiver module contains a high speed, high efficiency, low power consumption algaas led, a silicon pin photodiode, and the low power driven bipolar integrated circuit. the ic contains a led driver circuit and a receiver, that provides the rx output supporting 2.4k to 115.2 kb/s irda signals, at both irda 1.0 communication mode (communication distance of 1.0m at emitter i f = 300 ma), and irda 1.2 low power option communication mode (communication distance of 0.2m at emitter i f = 27 ma) this dual mode communication capability provides wider application use in final product, as a wireless data link with pcs, pdas, or any other irda compliant application already introduced to the market place. though the GP1H20 transceiver module is operated at 2.7v, the module can still be operated at 5.5v without any performance desiccation. the manufacturers would surely get the advantage of energy saving design in any application field, with having alternatives of supply voltage, for other components. further more, the GP1H20 transceiver module does have the built-in shut-down mode for those who are very conscious about the current consumption, by reducing the current consumption down to 1 ma (max.) at the shut- down mode.
