INTRODUCTION

This specification applies to the outline and characteristics of IrDA 1.2 type (data rate 2.4 kbps to 115.2 kbps, low power option compliant).

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 immediate or potential defects.

– Cleaning solvent: The cleaning shall be carried out

with ethyl alcohol, methyl alcohol, isopropyl alcohol.

• In order to prevent electrostatic damage to the inte-

grated circuit, handle this device in a static-free environment 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 0.5 ms or more that is specified by IrDA. This turn around time means the time

and PBBS are not used in this device.

115 kbps Transceiver

that this device does not temporarily detect the inconsistent signal, since the transmitted light from the transmitter side reaches the detector side of the same transceiver.

• When designing the system (program), consider that

0.3 ms or more (at T essary to return from shut-down mode to readyoperation 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 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 Physical Layer Link Specification’ published by the Infrared Data Association. Faulty operation may occur, if a signal method other than that specified is used.

• RXD pinout remains at high-level output in shutdown mode. The RXD pinout is CMOS output, and other CMOS outputs must not be directly connected to this pinout, as it does not conform to tri-state output.

• In circuit designs, make allowance for the degradation of the light emitting diode output that results from longterm continuous operation (50% degradation/5 years).
