KSZ8795CLXIC’s Ethernet Controller with On-Chip Termination

Ethernet controllers are interface Integrated Circuits (ICs), designed to allow communications using an Ethernet protocol. Most of the time, it uses hardware components to make this drive.

Now, in this article, you will find out what the KSZ8795CLXIC has to offer, in terms of improving the communications between consumer electronics.

Ideal for Embedded Designs

These Ethernet interface ICs are ideal for embedded designs and applications, especially those using the Ethernet protocol.

Ethernet interface ICs also make up a bulk of the semiconductor packages, ranging from SOIC, QFN, and TQFP.

KSZ8795CLXIC as an Ethernet Controller


Before going further, we want to mention that Ethernet interface ICs come in different packages. KSZ8795CLXIC is based on the Ethernet Controller package.

As an Ethernet Controller, it is used to determine the basis of the packet of data, i.e., if it is ideal for use with the local computer or another computer based on the same network.

At this point, the interface IC has a decision to make and the accuracy of that decision reflects in the next move.

For example, if the Ethernet Controller detected that the packet of data is meant for the other computer (using the same network), it would discard the data.

It would only admit or allow the passage of the packet of data if it is meant for the local computer. In that case, it would pass along or relay the packet of data to the processor.

A Wide Selection of Power Solutions

In addition to segmenting the packet of data, KSZ8795CLXIC’s Ethernet Controller also ensures that the performance is optimum. It supports a wide range of power solutions, including the Wake-on LAN (WoL), Energy Efficient Ethernet (EEE) and PME.

Dynamic Clocking Capabilities

The ability to “clock” perfectly or distribute clock functions across the entire device is an important factor to consider. However, in some instances, and depending on the use case, the clocking performance might not be optimum.

That is why we are pleased to see the provisions to mitigate against that on the KSZ8795CLXIC Ethernet Controller. The controller ensures the best clocking performance, by providing a Dynamic Clock Tree Control. This control function works by reducing clock usage in areas where there is little or no need for the same.

That way, KSZ8795CLXIC’s clocking performance is only limited to the circuit board areas where they are required.

Crossover Support

Since Ethernet Controllers help in packet data segmentation, it is imperative to see it through. Therefore, enabling interfacing across the supported applications is a must. However, the task can be daunting and will likely take up more time.

It is on this premise that KSZ8795CLXIC features the HP Auto MDI/MDI-X Crossover Support. This function eliminates the need for differentiation of the crossover cables from the straight cables – especially for targeted applications.

Excellent Management Interfaces

In addition to supporting some of the best power management solutions, KSZ8795CLXIC also supports the best managerial interfaces.

KSZ8795CLXIC supports two (2) management interface nodes, which include MIIM and SPI only. It also extends the support to all the PHY registers through the MDC/MDIO interfaces; the SPI access all registers and the MIIM node access.

The Tail Tagging Mode

Recall that the major use case for an Ethernet Controller is to segment packet data. The segmentation process is bolstered by the Tail Tagging Mode. It is a function, dedicated to informing the processor on which data to prioritize and which not to.

Ideally, it adds a byte before the FCS and is supported on Port 5. When it is time to segment the data, the mode informs the Process on which Ingress Port the packet data is to be received – and whether it is to be prioritized or not.

Power Reduction

KSZ8795CLXIC is all-in for excellent thermal performance and power management. That is why it uses the on-chip termination resistors, alongside the internal biasing to enable differential pairs to cut down on excessive power usage.

Provision of Multiple CPU Data Interfaces for Port Configuration

KSZ8795CLXIC supports multiple CPU data interfaces, via the effective addressing of the emerging and the current fast Ethernet and Gigabit Ethernet applications.

That enables the multiple CPU data interfaces to work with the aforementioned Ethernet applications for the Port 5 GMAC configuration. The configuration, when effected, will see the Port 5 made into any of the following modes:

  • RMII
  • GMII
  • MII and;

Advantages of Working with Ethernet Controllers

KSZ8795CLXIC offers the following benefits:

1. Easy Interfacing

Most Ethernet controllers make an interface or establish connections with multiple devices with ease.

2. Small Body Size

Smaller body sizes are in the favour of Ethernet controllers, as that permits for the usage in many small form-factor circuit designs.

3. High-Performance Optimization

KSZ8795CLXIC is also optimized for use with the high-performance applications. Examples of supported applications are:

  • Networked measurement and control systems
  • Set-top/game box
  • Integrated DSL/cable modem
  • VoIP Phone
  • Wireless LAN Access Point + Gateway
  • Automotive applications
  • Standalone 10/100 Switch
  • Industrial control applications
  • Broadband Gateway/Firewall/VPN
  • It is also used with Gigabit Ethernet applications and cost-sensitive applications.

Other Types of Ethernet Interface ICs

KSZ8795CLXIC is an Ethernet Controller and that makes it one of the Ethernet Interface ICs. Here are some of the others:

4. Ethernet Transceivers

The primary function of an Ethernet transceiver is to connect the electronic devices, including computers to a network.

The Ethernet transceiver comprises some of the high-powered components, ranging from a receiver and a transmitter.

Both of those components help the transceiver to detect the incoming signals and to place the signals unto the network.

5. Ethernet Switches

These are dedicated switches that provide both switching and providing control to the circuit board.

The ideal composition of the Ethernet switches is to circuit board of an Ethernet switch. The switches also work in unison with the fans and power supply with one goal – to bolster the optimum switching capabilities of the IC.


KSZ8795CLXIC’s combination of the on-chip termination resistors and internal biasing helps in reducing power consumption. It also simplifies the board layout, saves more PCB spaces and offers an overall cost-reduction.
