DESCRIPTION
The SHARP GP2W0001YP is one of the smallest
transceiver modules. Even at low operating voltages,
it provides a reliable interface between logic and IR
signals for through-air, serial, half-duplex IR wireless
data links and is designed to satisfy IrDA physical
layer specifications.
The GP2W0002YP is the same module, and adds an
integral Electro-Magnetic Interference (EMI) shield.
While IR energy is inherently immune to EMI, the receiv-
ing devices themselves are not. This shield provides an
additional level of protection in electromagnetically noisy
environments such as PCs and other digital products.
The SHARP GP2W0001YP/GP2W0002YP infrared
transceiver modules contain a high speed, high effi-
ciency, low power consumption AlGaAs LED, silicon PIN
photodiode, and a low power bipolar integrated circuit.
The IC contains an LED driver circuit and a receiver, pro-
viding the Rx output. IrDA data rates of 2.4 Kbps to
115.2 Kbps are supported at both 20 cm and one-meter
distances. At the one-meter range, emitter current is
approximately IF = 300 mA and in the IrDA Low Power
Option communication mode IF = 27 mA. This dual
mode communication capability provides wider product
applications, such as a wireless data link with PCs,
PDAs, or any other IrDA compliant application already
on the market.
The GP2W0001YP/GP2W0002YP transceiver
modules may be operated over a power supply range
of 2.7 V to 5.5 V without any performance degradation.
This provides a single part with a wide variety of
design applications.
For power-conscious applications, the transceiver
module has a built-in Shutdown mode. This reduces
the receiver's current consumption to 1 µA (MAX.) dur-
ing Shutdown. The transmitter and receiver circuits are
separate, allowing the transmitter LED to be driven
when in Shutdown mode.
OUTLINE DIMENSIONS
The dimensions shown in Figure 1 and Figure 2 are
only for design reference, and are subject to change
without notice. The metal shield case version
GP2W0002YP, (for excellent noise immunity) is shown
in Figure 2. Contact your local SHARP office for the lat-
est device specifications.

Cabinet and IR Cosmetic
Window Design Tips
Figure 17 with its calculations illustrates the design
tips for a cabinet and an IR cosmetic window with ±18°
viewing angles in the vertical and horizontal axes. All
transceiver dimension values are for reference, and
are in mm.
The optical window size should be the minimum size
of W × H, either rectangular or elliptical, to maintain
IrDA data transfer performance. The dimensions for W
can be calculated by the formula:
W = 2 × L × tan(18 + w)
And the dimensions for H can be calculated by the
formula:
H = 2 × L × tan(18 +h)
In the case where the viewing angle is +18°, which
conforms to or exceeds the IrDA Serial Infrared Physi-
cal Layer Link Specifications. Values to be calculated
with above the formula must be given in mm.
