KSZ8091RNACA-TR application field and working principle

The popular KSZ8091RNACA-TR is an efficient, integrated interface with cost-efficiency and a wide range of applications. Powered by Micrel\'s versatile SKY98123LEN-TR transceiver and KSZ8091RNCA-TR transceivers, the family of devices offers integrated solutions for various data transmission and processing needs.

Application fields

This interface can be used in a variety of industrial and commercial applications, such as Ethernet and other real-time networks, as well as in internet and wireless networks. It is also well-suited for a number of medical and automotive systems, which require reliable and secure communications and data transmission. Furthermore, the KSZ8091RNACA-TR interface is compatible with a wide range of physical layers, including RS-232, RS-422 and RS-485, Ethernet and proprietary network protocols. Additionally, the interface can be used as an integrated solution for serial communication, Ethernet switching, Ethernet bridging, and power-line communications.

Working principle

The KSZ8091RNACA-TR interface works on a transceiver, which integrates a single transmitter and receiver pair into an intelligent interface. The transceiver automatically regulates the amount of power needed whether it is transmitting, receiving, or idle, enabling more efficient energy utilization. To increase the range and speed of data transmission, the KSZ8091RNACA-TR transceiver comprises a pair of balanced differential line receivers. The receiver has the capability to extend the transmission range up to 200 metres, enabling data transfer from long distances, even in noisy environments. Moreover, the device supports differential signalling that can reduce EMI/RFI, and is capable of running at speeds up to 500kbit/s for short range transmissions, up to 1.6Mbit/s for longer ranges. Additionally, the transmitter features two output stages, which enable high current and low-voltage support, as well as reduced power dissipation.

The KSZ8091RNACA-TR transceiver also features a physical-layer interface, which is designed to assist networkers in using a simple, efficient and secure interface. The device consists of a MII (Media Independent Interface), which helps to reduce the complexity of implementing an Ethernet interface. This allows quick connection of two or more devices, without requiring additional hardware or software. Moreover, the on-chip LAN-PHY mode supports a variety of media types and speeds, enabling a connection between two or more devices.

The physical-layer interface also facilitates efficient noise reduction, which is enabled by a number of on-chip peripheral functions, such as input buffers and transition-matched output drivers. Additionally, the device is equipped with a reliable data link layer and is capable of providing a link for up to sixty-four nodes. This enables the KSZ8091RNACA-TR to create a reliable, secure and efficient communication network, ideal for complex industrial and data transfer applications.
