What is the difference between Sgmii and SerDes?
SGMII performs the same task, extended to include gigabit Ethernet, although it can be used for 10/100 Mbit/s TX/RX as well. SerDes technology, which is often used with SGMII, provides LVDS (low-voltage differential signaling) for converting between serial and parallel signal routing, as shown in the figure below.
What is Sgmii interface?
The serial gigabit media-independent interface (SGMII) is a variant of MII used for Gigabit Ethernet but can also carry 10/100 Mbit/s Ethernet. It uses differential pairs at 625 MHz clock frequency DDR for TX and RX data and TX and RX clocks. It differs from GMII by its low-power and low pin-count 8b/10b-coded SerDes.
Is Sgmii an Ethernet?
The Serial Gigabit Media Independent Interface (SGMII) is a connection bus for Ethernet Media Access Controllers (MACs) and Physical Layer Devices (PHYs) defined by Cisco Systems.
What is the speed of Sgmii?
It can also be used as a serial communication bus between the PowerQUICC™ MPC8313E and other peripherals such as through a backplane. A key advantage of SGMII is that it can operate at multiple speeds of 10/100/1000 Mbps.
What is Sgmii Ethernet?
The Serial Gigabit Media Independent Interface (SGMII) is a connection bus for Ethernet Media Access Controllers (MACs) and Physical Layer Devices (PHYs) defined by Cisco Systems. It replaces the classic 22-wire GMII connection with a low pin count, 4-pair, differential SGMII connection.
What is the difference between SGMII and 1000BASE-X?
SGMII: Serial Gigabit Media Independent Interface, it is used to interface the MAC layer of the Ethernet to the PHY layer. 1000BASE-X : Optical fiber channel that meets GigaBit Ethernet protocol requirments. Not open for further replies.
What is the difference between SGMII and RGMII?
RGMII supports Ethernet speeds of 10 Mbit/s, 100 Mb/s and 1000 Mbit/s. The Serial Gigabit Media Independent Interface ( SGMII) is a sequel of MII, a standard interface used to connect an Ethernet MAC-block to a PHY. It is used for Gigabit Ethernet (contrary to Ethernet 10/100 for MII).
What is the SGMII mode of the Xilinx Base-T core?
• The core must operate in SGMII mode to provide BASE-T functionality and use the twisted copper pair. The GMII of the 1000BASE-X PCS/PMA or SGMII core is shown connected to an embedded Ethernet Media Access Controller (MAC), for example, the Xilinx Tri-Mode Ethernet MAC core.
Can the SGMII core be interfaced with an external PHY?
Figure 3-11 shows a simplified diagram of a common situation where the core, in SGMII mode, is interfaced to an external PHY device . A common oscillator source is used for both the FPGA and the external PHY. Send Feedback 1000BASE-X PCS/PMA or SGMII v14.3 www.xilinx.com102
