Gigabit Ethernet (GbE) Controller
11.1
Introduction
The Gigabit Ethernet (GbE) controller is a PCI device with PCI Express* architecture
capabilities integrated in the SoC. The controller provides an interface that supports
four independent gigabit Ethernet Media Access Control Ports (MACs). Each MAC has
SGMII, SerDes, 1000BASE-KX, and 2.5-GbE configuration capability. Routing the
interfaces either directly to a backplane or connecting to an external SGMII-capable
Physical-Layer device (PHY) enables 1000BASE-T connections.
Note:
An MDIO/MDC connection is required for SGMII support. Refer to Appendix D of the
Intel
®
Atom™ Processor C2000 Product Family Platform Design Guide (PDG) for
guidance on which PHYs are supported.
The integrated GbE controller provides an interface for system management. The
interface can be configured to operate as a Network Controller Sideband Interface (NC-
SI) or as an SMBus interface. The GbE controller can provide the clock for each
interface.
The GbE controller also provides LED control, programmable pins, and an SPI interface
for the controller EEPROM.
Note:
SoC customers are advised to contact Intel concerning their GbE EEPROM needs. Intel
provides a number of EEPROM image files for SoC customers to use in their designs.
These files are considered “starter images” and to some extent can be altered for a
customer’s particular usage.
