What is SGMII mode?
The serial gigabit media-independent interface (SGMII) is the interface with the lowest pin count available for connecting compatible MACs and PHYs. It can also be used as a serial communication bus between the PowerQUICC™ MPC8313E and other peripherals such as through a backplane.
What is Sgmii used for?
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.
Is SGMII 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 Rgmii in Ethernet?
Summary. The Reduced Gigabit Media Independent Interface (RGMII) is an alternative to the Gigabit. Media Independent Interface (GMII). In this application note, an RGMII adaptation module is used to reduce the number of pins required to connect the Gigabit Ethernet MAC to a Gigabit PHY from 24 to 12.
What is difference between RGMII and Sgmii?
The pin count for all three interfaces are different. GMII and RGMII operate at 125 megahertz and SGMII operates at 625 megahertz. The important difference between RGMII and GMII is the pin count. Although RGMII has half the pins of GMII, it can still operate at gigabit speeds using the same clock frequency.
What is DP83848?
DP83848-EP ACTIVE The DP83848-EP was designed to allow Ethernet connectivity in the harshest environments. Our device meets IEEE 802.3u standards over a military temperature range of –55°C to 125°C. This device is ideally suited for harsh environments for example avionics, defense and industrial control applications.
What is 1000BASE KX?
1000BASE-KX is a standard used for connectivity over Electrical Backplanes. This variant uses electrical signaling speed. It has a distance capability of 1 meter. 1000BASE-SX is a standard used for near infrared optical connectivity over Multi-mode fibers.
What is SerDes FPGA?
A SerDes is an integrated circuit or device used in high-speed communications that converts between serial data and parallel interfaces, in either direction.
What is 1000BASE?
1000BASE-X is a group of standards for Ethernet physical layer standards, specified within the IEEE 802.3. It is used for gigabit Ethernet connections that transmit data mainly over fiber optic cable, and sometimes over copper-shielded cable.
Is 1000Base 1gig?
As the name suggests, Gigabit Ethernet, 1GE, allows the transfer of data at speeds of 1000 Mbps or 1Gbps. It is particularly easy to install because the 1000BASE-T variant is designed to run over Cat 5 UTP (unshielded twisted pair) Ethernet cables that are widely and cheaply available.
What is the difference between SX and LX fiber?
SX stands for short wavelength. The standard specifies a distance capability between 220 meters and 550 meters. 1000BASE-LX can run over both single mode fiber and multimode fiber with a distance of up to 10 km and 550 m, respectively.
What is high speed SerDes?
A SerDes (Serializer/Deserializer) is an integrated circuit or device in use in high-speed communications that converts between serial data and parallel interfaces in either direction. It converts parallel data into serial data so that it can travel over media that doesn’t ordinarily support parallel data.
