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 sur­face 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

– Ultrasonic cleaning: The effect of ultrasonic

– Cleaning solvent: The cleaning shall be carried

• In order to prevent electrostatic damage to the inte­grated 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 200 µs or more that is spec­ified 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 T
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 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 is a pullup (260 kΩ TYP.) to V
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 T
fore it is recommended to operate over T
