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.
The SHARP GP2W0110YPS/GP2W0114YPS
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-
cuit and a receiver that provides the Rx output
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.
The GP2W0110YPS/GP2W0114YPS include a con-
stant-current source in the LED driver circuit that elimi-
nates the need for an external current limiting resistor in
the LED circuit.
The IrDA Low Power Option Standard is most suit-
able for telecommunication products and mobile termi-
nals, such as cellular phones, paging devices, and
PDA-cellular combined multimedia devices. The trans-
ceiver modules provide wireless data link capability for
cellular phones and pagers, PDAs, or any other IrDA
application already on the market.
The transceiver modules’ receiver electronics oper-
ate at voltages from 2.0 V through 3.6 V without any
performance degradation. The split-voltage supply
allows the LED voltage to come from a separate supply.
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.
This provides manufacturers with the advantage of an
energy saving design in any application field, with alter-
natives for supply voltage and flexibility for other compo-
nents. The GP2W0110YPS/GP2W0114YPS
transceiver modules have a built-in 0.1 µA Shutdown
mode for those applications that are very conscious
about current consumption. Additionally, the
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.
