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 I_F = 300 mA and in the IrDA Low Power
Option communication mode I_F = 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.
