Stratix IV GX Edition Reference Manual

Table 2–23 lists the SPI Bus pin connections to the FPGA for the power measurement

circuitry.

Table 2–24 lists the ADC

component reference and manufacturing information.

Ethernet Port

The Stratix IV GX transceiver signal integrity development board incorporates a triple

speed 10/100/1000 Base-T Ethernet port. The implementation uses a discrete Ethernet

PHY device and RJ45 connector with integrated magnetics connected to the FPGA.

Figure 2–9 shows the block diagram of the Ethernet port.

Table 2–25 lists the components used for the Ethernet port and the manufacturing

information.
