TLK2226GEA Application Field and Working Principle

Introduction

TLK2226GEA is a quad-channel gigabit Ethernet transceiver, long reach and low power, a combined media access controller (MAC)/physical layer (PHY) transceiver unit. This device is designed specifically to reduce system power and physical sizes while maintaining high performance and reliability. It typically serves as the physical layer interface to host/application processors, routers, switches, and bridges in wire-line transmission systems. This interface is integrated such that it can connect to various types of physical layers and communications media, including Gigabit Ethernet links, Synchronous optical network (SONET) links, and Synchronous Digital Hierarchy (SDH) links. As such, the TLK2226GEA, which can be broadly found in the data network field, is a versatile device for many applications which enhances the use of gigabit Ethernet.

Application Fields

The TLK2226GEA are commonly found in data networks to serve as an interface transceiver typically between host/application processors and Gigabit Ethernet links. These transceivers are also used to connect to various types of physical layers and communication media, such as SONET links, SDH links, and storage area networks (SANs). In addition, the TLK2226GEA are now being used in emerging applications including ethernet in the first mile (EFM) and artificial intelligence (AI) applications.

EFM and AI

Ethernet in the first mile (EFM) is also commonly known as "Fast Ethernet over Copper." This technical application is becoming increasingly popular for Metropolitan and Wide Area Networks (MANs and WANs). This technology allows for the ability to transport data and voice over simple copper-based network links such as twisted-pair and fiber optic cables. These fiber optic cables are typically used to extend the LAN into parts of the metropolitan area, allowing longer reach and improving performance. As such, the TLK2226GEA transceivers are commonly used in EFM to enable a simple and flexible network featuring gigabit performance.

Artificial Intelligence (AI) applications are also increasingly utilizing the TLK2226GEA transceivers. Such applications typically require high speed data rates and advanced signal processing capabilities that can effectively handle the powerful and intensive computations. As such, these transceivers are being used to enable effective machine learning and artificial intelligence algorithms. Specifically, the TLK2226GEA transceivers enable the ability to support sensing, control and actuation capabilities for these emerging technologies.

Working Principle

The TLK2226GEA transceivers feature enhanced signal processing capabilities to enable extended range and low power consumption. This transceiver works on the principle of backplane coding in order to improve signal quality and reliability. Backplane coding is used to reduce noise and electromagnetic interference (EMI) on the signal transmission. The backplane coding utilizes a differential signaling scheme to establish a differential signal between two conductors. The signals are sent across the two conductors, and the receiving device detects the opposite of the signal sent, thus creating a differential couple. This enables the signal transmission to be more reliable and noise resistant.

In addition, the TLK2226GEA transceivers also utilize forward error correction (FEC). The FEC encodes the data so that even if the signal is corrupted by noise, the transmitting and receiving devices can still interpret the intended data. This enables extended transmission range and improved system performance.

Conclusion

The TLK2226GEA transceivers are commonly used in data networks as an interface between various physical layers. Additionally, emerging technologies such as EFM and AI applications are enabled by the use of these transceivers. The enhanced signal processing capabilities and backplane coding principles provide high-speed data rates, extended range and improved system performance. The advanced signaling capabilities combined with the FEC encoding provide a reliable, low-power and extended reach solution for many applications and emerging technologies.
