Interfacing the SX-560 to the OEM Device
In order to connect the SX-560 module to your device, you will need to provide either a custom
daughtercard or a special cable. Both of these solutions will require a 40-pin female connector on one
side, with the appropriate connector(s) for connecting to your device’s circuitry on the other side. The
custom daughtercard is generally a superior solution because it provides better mechanical connections
for greater overall system reliability.
A good model for a custom daughtercard is the Silex SX-560-6900 Evaluation Daughtercard (see chapter
2 for a discussion of the Evaluation Daughtercard). To assist you in the design of your daughtercard, we
have therefore included the schematics of the Evaluation Daughtercard in figure 22.
The major design considerations for the SX-560 are as follows:
• 40-pin OEM Header. This is the primary mechanism for communications between the OEM
device and the SX-560. This section describes the pinout and the mechanical considerations.
• Antenna Connectors. The two U.FL connectors can be used to connect a variety of antennas.
• General Purpose I/O (GPIO). The GPIOs can be used to control LEDs and for a variety of other
purposes.
• Power. The power requirements for the SX-560 are stated in this chapter.
Each of these design considerations is covered in the following sections of this chapter.
