2023年9月28日 · SGMII, which was defined by Cisco, utilizes two pairs of SERDES / LVDS differential buses to carry transmit and receive data at 1.25 Gbps. A differential receive clock is also defined but is optional and typically not used.

2020年9月30日 · 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. SGMII vs. SerDes example implementations.

2024年7月22日 · SerDes technology, often used with SGMII, provides LVDS (Low-Voltage Differential Signaling) for converting between serial and parallel signal routing. This article explores the key differences between these interfaces, focusing on their functionality, use cases, and impacts at the MAC layer.

2021年12月31日 · SGMII is a customized interface for Gigabit Ethernet, focusing on optimizing data transfer between the MAC and PHY. However, for SerDes, which is a generic interface, this interface can be applied to a wider range of application scenarios …

The SERDES interface is operating as a SGMII MAC device in this mode. This SGMII interface can be connected to another SGMII PHY device that supports either copper or fiber media interface.

2014年12月3日 · I was wondering what the exact difference between SGMII and 1000Base-X is, because both seem very similar. Is the "big" difference only the physical medium they are supposed to be transmitted on?

过去主要用于光纤通信的 串行通信 技术—— SERDES 正在取代传统并行总线而成为高速接口技术的主流。 本文阐述了介绍SERDES收发机的组成和设计，并展望了这种高速串行通信技术的广阔应用前景。 SERDES是英文SERializer (串行器)/DESerializer (解串器)的简称。

The KeyStone II SerDes interfaces consist of two main variants of the SerDes PHYs - PHY-A and PHY-B. Within PHY-A, there are 2 variants: PHY-A 2 Lane and PHY-A 4 Lane.

On our product, the SFP cages are hooked up directly to the SerDes pins coming off the switch. We're trying to understand the consequences of doing this vs. say having an SGMII interface hooked to that cage.
