NET-FMC Development Kit

1-1 Package Contents

The Terasic NET-FMC is a Gigabit Ethernet transceiver with an FMC interface. It offers
network transfers of up to 1 Gbps with the host board using an FMC connector. Also, it
provides a fully integrated Ethernet solution enabling fast implementation design,
shortening development times, and allows you to focus on the core functions of the system
design. Lastly, the NET-FMC can be connected any FMC(HPC) interfaces.

 Ethernet RJ45 Connector x4.
 Ethernet PHY chip 88E1111 x4.
 FMC Connector(HPC).
 Mode Switch x4.
 Link Status LEDs Group x4.

2-1 Features

The NET-FMC board has many features that allow users to implement a wide range of
design circuits, from simple circuits to various multimedia projects.
The following hardware is provided on the board:

 Package Interface: VITA 57.1 FMC, 2.5V I/O-standard.
 Ethernet PHY module:

Chip P/N: 88E1111.
10/100/1000BASE-T IEEE 802.3 compliant.
Support MAC Interface: GMII/MII, RGMII, SGMII.

 Ethernet RJ45 Connector x4:

Use standard Cat 5 UTP cabling.

 Mode Switch：

Support GMII/MII, RGMII, SGMII.

 Four 25-MHz reference clock driven from dedicated oscillator.

2-2 Block Diagram of the NET-FMC Board

Figure 2-3 shows the NET-FMC Block Diagram. Four 25 MHz reference clock driven from

dedicated oscillator are required for Ethernet PHY 88E1111. FMC Connector transmit the
data between host board and Ethernet PHY 88E1111 through MAC interface. Also,
four-port integrated 10/100/1000 Gigabit Ethernet Transceiver supported
SGMII/GMII/MII/RGMII MAC interfaces is installed for direct connection to a MAC/Switch
port. There are four group LEDs indicting the link status.

2-3 Connectivity

Terasic NET-FMC is able to connect to any FPGA development kit equipped with
FMC(HPC) connector. The below picture Figure 2-4 shows the connections with TR5
board.

2-4 Mode Switch x 4 Setting

The NET_FMC card provides four Ethernet ports (ETH0 ~ETH3) via four Marvell 88E1111
Ethernet PHY chips. Each switch (SW0~SW3) is corresponding to one Ethernet port to
switch Ethernet port work modes from RGMII to GMII/MII or SGMII, SW0 is used for ETH0
port, SW1 is used for ETH1 port, SW2 is used for ETH2 port and SW3 is used for ETH3
port. Table 2-1 describes the working mode switch settings for ENET0 ~ ENET3 port work
modes.

The default setting of the Ethernet Port is SGMII mode. Users can change Ethernet mode
by using the Mode Switch x4. Take ETH0 as an example.
Set ETH0 MODE on the NET_FMC card to RGMII mode (default). The SW0[6:1] on
NET-FMC should be set to 001010, as shown in Figure 2-5.

Figure 2-5 SW0 setting for ETH0 port RGMII mode

Set ETH0 MODE on the NET_FMC card to GMII/MII mode. The SW0[6:1] on NET-FMC
should be set to 001001, as shown in Figure 2-6.
