KSZ9031RNXIC

KSZ9031RNXIC is an Ethernet PHY Transceiver designed specifically for use in Edge-Core based Ethernet routers and switches. The device provides four 1G links and an RGMII interface for connecting to the host controller. This transceiver supports four 1G full-duplex communication interface. It also provides four 1G full-duplex links for both isolated and non-isolated applications.

Application Field

The KSZ9031RNXIC is suitable for all kinds of applications, including data, Voice over IP (VoIP), video, multimedia, industrial control systems and Ethernet switching. It can be used in Edge-Core based Ethernet routers and switches. This PHY transceiver also has power saving features. It has configurable low-power modes, which enable the device to achieve a power saving of up to 30% compared to traditional transceivers.

Working Principle

The working principle of the KSZ9031RNXIC is based on Automatic Configuration and Link Local Networking. This PHY transceiver can automatically detect and configure the connected Ethernet equipment and send the information needed to establish the links between the devices. The Auto-Negotiation operation is managed by the device. It can detect the speed of both sides and negotiate the proper speed and mode by exchanging special frames called Link Pulse Messages.

The Auto-MDI-X (Auto-MDIX) function is available to eliminate the need for cross-over cables. This function can automatically change the pin assignment of the TX and RX signals when an Auto-MDIX enabled device is connected. In addition, the KSZ9031RNXIC supports advanced features such as flow control, link message buffering, on-chip status reporting and error counter.

Conclusion

The KSZ9031RNXIC is an innovative PHY transceiver designed for Edge-Core based Ethernet routers and switches. It supports four 1G full-duplex communication links, provides power saving features and has advanced features such as flow control and on-chip status reporting. This transceiver can automatically configure and connect the connected Ethernet equipment and provide the required information to establish the link. Furthermore, it offers Auto-MDI-X to eliminate the need for a cross-over cables.
