GP2W0110YPS/GP2W0114YPS
IrDA Technical Information
Low Power Infrared Transceiver
DESCRIPTION
The SHARP GP2W0110YPS/GP2W0114YPS are
low-power, short-range infrared transceiver modules.
They meet the Mobile Communication Low Power
Option within the IrDA Specification for the 20 cm com-
munication range. When operating at lower supply volt-
ages, these units provide a reliable interface between
logic and IR signals. Applications include through-air,
serial, half-duplex IR wireless data links at rates up to
115 kbit/s and the devices are designed to satisfy the
IrDA Physical Layer Specifications.

FEATURES
• IrDA Low Power Option Compatibility for Telecom-
munication and Mobile Terminals
infrared transceiver modules contain a high speed,
high efficiency, low power consumption AlGaAs LED,
silicon PIN photodiode, and the low power driven bipo-
lar integrated circuit. The IC contains a LED driver cir-

supporting 2.4 kbit/s to 115.2 kbit/s IrDA signals. They
meet the IrDA Low Power Option Communication
Standard link distance of 0.2 m with low power devices
and 0.3 m with standard devices.

allows the LED voltage to come from a separate supply.
APPLICATIONS
• Telecommunication Products
An example is in cell phones where the LED may oper-
ate from the battery and the receiver and logic section
is supplied from a regulated supply at a lower voltage.
– Cellular Phones
This provides manufacturers with the advantage of an

natives for supply voltage and flexibility for other compo-
nents. The GP2W0110YPS/GP2W0114YPS
transceiver modules have a built-in 0.1 µA Shutdown

GP2W0110YPS/GP2W0114YPS have a tri-state out-
put, which allow their use in applications where one port
connection may be connected to more than one device.
The included shield is appropriate in applications
where Electro-Magnetic Interference (EMI) is a con-
cern. Infrared energy is immune to EMI, but the receiv-
ing PIN photodiode is somewhat sensitive to EMI. This
is the case in all IR communication devices.

Designing an IR Cosmetic Window
Figure 15 and its calculations show an example and
design tip for a cabinet and IR cosmetic window with
+18° viewing angles, in both vertical and horizontal
axes. All values for the transceiver dimensions are only
for design reference, and are given in mm. The IrDA
specifications require a +15° viewing angle at the trans-
ceiver. The +18° angle shown provides a little extra
clearance to allow for slight manufacturing variations,
so that the required angle is always met.
The optical window size should be the minimum size
of W × H rectangular or elliptical in order to maintain
IrDA data transfer performance. The dimensions for
width can be calculated by the formula of:
W = 2 × L × tan18 + w
And the dimensions for height can be calculated by
the formula of:
H = 2 × L × tan18 + h
In the case of having a view angle of ±18°, which
conforms to or exceeds the IrDA Serial Infrared Physi-
cal Layer Link Specifications. Any values to be calcu-
lated with above formula are given in mm.
The dimension 7.9 mm as used in Figure 15 and its
calculations, is the physical length of the transceiver.
This distance also includes the side angles of the optical
lenses to simplify the overall calculation. The height of
the transceiver is 2.15 mm with the shield; however, the
actual transceiver face in the optical resin is 2.0 mm.
These dimensions are listed in the mechanical drawings.
