OEM Interface
The OEM interface is a 40-pin header that is used to connect the SX-550 module to the SX-550-6900
Evaluation Daughtercard. It will also serve as the primary means of communications between the SX-550
and your OEM device (refer to Chapter 5 for information on using this header to connect with your
device).
Table 3 shows the OEM interface pinout, J5, for the Evaluation Daughtercard. Table 4 shows the OEM
interface signal descriptions. Please note that the OEM interface signals are not directly accessible from
the OEM header when the Evaluation Daughtercard is used. Rather, these signals are available through
convenient connectors on the Evaluation Daughtercard, such as the RJ45 Ethernet connector and the 9-
pin serial connectors. These connectors are described later in this chapter.
All input and output signals, except the differential signals, are 0 to 3.3 V logic signals.
*GPIO_7 is fixed as a switch input (Test Button) and GPIO_8 is fixed as an LED output (Power).
