2. Description
The SHARP GP2W0110YP0F is a low-power,
short-range infrared transceiver module. It meets the
Mobile Communication
low power option
within the
IrDA Specifications for 20-cm communication range.
This unit provides the interface between logic and IR
signals for through-air, serial, half-duplex IR wireless
data links at rates up to 115 kbit/s, and is designed to
satisfy the IrDA physical layer (PHY) specifications.
The SHARP GP2W0110YP0F infrared transceiver
module contains a high speed, high efficiency, low
power consumption AlGaAs LED, silicon PIN
photodiode, and the low power driven bipolar
integrated circuit. The IC contains a LED driver
circuit and a receiver that provides the RX output
supporting 2.4k to 115.2 kbit/s IrDA signals, meeting
the IrDA low power option communication standard
(link distance of 0.2m with low powered devices and
0.3m link with standard devices.)
The GP2W0110YP0F includes a constant-current
source in the LED driver circuit that eliminates the
need for an external current limiting resistor in the
LED circuit.
The low power option specification is most suitable
for telecommunication products and mobile
terminals, such as cellular phones, paging devices,
and PDA-cellular combined multimedia devices. The
transceiver module provides capability for a wireless
data link for cellular phones and pagers, PDAs, or
any other IrDA application already introduced to the
market place.
This transceiver module receiver electronics can
operate at 2.0V through 3.6V without any
performance degradation. The split-voltage supply
allows for the LED voltage to come form a separate
supply. An example is cell phones where the LED
may operate from the battery and the receiver and
logic section is supplied form a lower voltage
regulated supply.
This provides manufacturers with the advantage of
an energy saving design in any application field, with
alternatives for supply voltage and flexibility for other
components. The GP2W0110YP0F transceiver
module has a built-in 0.1-µA-shutdown mode for
those applications that are very conscious about
current
consumption.
Additionally,
the
GP2W0110YP0F has a tri-state output, which allows
its use in applications where one port connection
may be connected to more than one device.
The shield is appropriate in applications where
Electro-Magnetic Interference (EMI) is a concern.
Infrared energy is immune to EMI, however the
receiving PIN photodiode is somewhat sensitive to
EMI. This is the case in all IR communication
devices.

The V

voltage may be directly driven from the battery in the above design example. The V

associated with
the Receiver interface electronics may be supported by a power regulator or other device providing an efficient
regulated lower voltage source. This voltage may be as low as 2.0 Volts to 3.6 Volts, and the V

potential may
range from 2.0 Volts to 6.0 Volts.
An alternative is to connect the V

GP2W0110YP0F to go into previous applications where both of these voltage sources are connected. It is
