1 / 16 page  IrDA Data Sheet 1 GP2W0106YP IrDA Data Sheet 115 kbps Transceiver FEATURES • Built-in Photodiode • Operating voltage 2.0 V to 3.6 V • Conforms to eye safety IEC60825-1, without exter- nal resistor • This product shall not contain the following materi- als, and these materials shall not be used in the pro- duction process for this product. –CFCS – Halon – Carbon Tetrachloride – 1.1.1. Trichloroethane (Methylchloroform) – Specific brominated flame retardants such as the PBBOS and PBBS are not used in this device. INTRODUCTION This specification applies to the outline and charac- teristics of IrDA 1.2 type (data rate 2.4 kbps to 115.2 kbps, low power option compliant) optical data communication transceiver. NOTES • Caution should be taken to prevent the detector sur- face from being smeared with dust or dirt, or from being touched, as it may cause faulty operation. • Cleaning conditions: – Solvent cleaning: Solvent temperature 45°C or less. Immersion for 3 minutes or less. – Ultrasonic cleaning: The effect of ultrasonic cleaning on the device differs by cleaning bath size, ultrasonic power output, cleaning time, PCB size or device mounting condition, etc. Test the device under actual conditions and confirm that ultrasonic cleaning does not cause any immedi- ate or potential defects. – Cleaning solvent: The cleaning shall be carried out with ethyl alcohol, methyl alcohol, or isopropyl alcohol. • In order to prevent electrostatic damage to the inte- grated circuit, handle this device in a static-free envi- ronment and workstation. • External force applied to the device after mounting can cause mounting defects such as the terminal coming off. Be careful when handling the device and prevent objects from touching the device after mounting. • Refer to the ‘Precautions for Soldering’ section. • When the system (program) is designed, the turn around time from transmit to receive should be designed by considering 200 µs or more that is spec- ified by IrDA. This turn around time means the time that this device does not temporarily detect the incoming signal, since the transmitted light from the transmitter side reaches the detector side of the same transceiver. • Consider that 200 µs or more (at TA = 25°C, no input signal) is necessary to return from shut-down mode to ready-operation mode. In addition, thoroughly confirm the operation in the actual application. • When there is considerable external stray light or a light source is located near the transceiver, or the detector face receives considerable external stray light, a pulse other than desired signal output may be generated as noise on output terminal of the transceiver. Consider the layout and structure in your design to minimize disturbing light on the detector face. • When the sensor is adopted in an IR communication system, it should be used according to the signal method which is specified by ‘Serial Infrared Physi- cal Layer Link Specification’ published by the Infra- red Data Association. Faulty operation may occur, if a signal method other than that specified is used. • RXD pinout is a pullup (260 k Ω TYP.) to VDD in shut- down mode. See Table 1 and Figure 2. • In circuit designs, make allowance for the degradation of the light emitting diode output that results from long-term continuous operation (50% degradation/5 years). The light emitting diode output may be degraded quickly when operated at TA = -40°C, there- fore it is recommended to operate over TA = -20°C. |
