Test and Evaluation Board
Sharp Microelectronics has prepared an evaluation board for preliminary test of the GP2W0110YP0F transceiver.
This board has also been developed to support the GP2W0112YPS transceiver, and that is why there are two
resistor positions on the board. In the configuration for GP2W0110YP0F, R2 = 0 Ohms, and the R1 position is
open. (The position for R1 will be loaded when the board is used for GP2W0112YP.)
The new low power 20 cm transceivers are so small that soldering directly to the contacts on the device is not an
easy or effective connection method. Testing with an actual surface mount connection is the best method for
evaluation. The PCB provides the electrical interface and a good ground-plane for test purposes. Connector J1 is
the interface to the test system. The drawing shows that the device EMI shield should be connected to a good
Ground in your final system.
The value of capacitor CX1 is listed as 10 µF. This value should be modified to meet your system electrical noise
requirements. The decision should be based on the amount of system noise at the point where the IrDA
transceiver will be powered. Both time-domain and frequency-domain noise issues should be considered. One
common source of noise is switching power supplies, which need attention both on the power line and ground
return paths.
As shown, capacitor CX1 is the only external component needed with the transceiver. If the power supply filtering
in your system design is such that no capacitor is needed, there is no absolute requirement for it and that is a
decision left to the design engineer.
Note
powered from the same source, pins 2 and 10 needs to be externally connected.
Evaluation boards may be requested through any Sharp Microelectronics of the Americas Sales office.
