Hardware Specifications

The following section provides information about FM-XTDE4U2/4 main components and features.

Intel 82574L GbE Controller The 82574L is a single, compact, low power component that offer a fully-integrated Gigabit Ethernet Media Access Control (MAC) and Physical Layer (PHY) port. The 82574L uses the PCI Express* (PCIe*) architecture and provides a single-port implementation in a relatively small area so it can be used for server and client configurations as a LAN on Motherboard (LOM) design. The 82574L can also be used in embedded applications such as switch add-on cards and network appliances.

MAC

• Flow Control Support compliant with the 802.3x specification
• VLAN support compliant with the 802.1Q specification
• MAC Address filters: perfect match unicast filters; multicast hash filtering, broadcast filter and promiscuous mode
• MAC loopback

PHY

• Compliant with the 1 Gbps IEEE 802.3 802.3u, 802.3ab specifications
• IEEE 802.3ab auto negotiation support
• Full duplex operation at 10/100/1000 Mbps
• Half duplex at 10/100 Mbps

Pericom PI6C20400 1-to-4 Differential Clock Driver Pericom Semiconductor's PI6C20400 is a high-speed, low-noise differential clock driver/buffer compatible with CML and HCSL differential I/O technology. The device distributes a differential input clock to four differential pairs of clock outputs either with or without PLL. The clock outputs are controlled by input selection of several static control signals and Host SMBus interface. The device oriented and designed for PCI Express applications.

SPI NOR Flash The 82574L requires non-volatile memory content for initialization and configuration. The NVM is connected to a single Serial Peripheral Interface (SPI). The 82574L is compatible with many sizes of 4-wire SPI NVM devices. The required NVM size is dependent upon system requirements. FM-XTDE4U2/4 NVM is implemented with Winbond W25Q80BL 8Mbit Flash memory.
