Introduction

KSZ8841-16MVLI, developed by the American semiconductor company Micrel, is a small size and low-cost 10BASE-T and 100BASE-T compatible Ethernet transceiver. It is specifically designed to provide an interface between Ethernet physical wires and Ethernet equipment such as microcomputers, workstations, and cable and portable computers. The transceiver supports 10 Mbps and 100 Mbps data transmission and provides full-duplex and half-duplex mode operation. It provides a wide range of features like integrated ESD protection, low current operation, low interference emission, and low power consumption. The power and ground pins are optimized to meet the 3.3V power standard and the pin-outs are symmetrical, making it easy to use in different applications.

Application Field

The KSZ8841-16MVLI transceiver is primarily used in local area networks (LAN) and in network applications. It is mainly used to connect ethernet equipment such as workstations, microcomputers, hubs, switches and other network devices. It is especially suitable for communications that require low-cost solutions such as home networks and industrial automation systems. It can also be used in automotive applications, providing an interface between the vehicle’s electronics and the exterior communications systems.

Working Principle

The KSZ8841-16MVLI transceiver works by converting the digital data into electrical signals that can be transmitted through the cable. The transceiver has two main components: a PHY chip and a MAC chip. It supports four different levels of operation in full-duplex and half-duplex modes. In half-duplex mode, the transceiver is configured to transmit and receive data. The PHY chip receives data from the MAC chip and sends electrical pulses through the cable. The pulses will be picked up by the receiving device, which will convert them back into the digital data. In full-duplex mode, the transceiver is configured to simultaneously transmit and receive data. The transceiver will convert the digital data from the MAC chip into electrical signals that can be sent through the cable. The signals will be picked up by the receiving device and converted back into the digital data. The transceiver will then convert the received data from the receiving device into electrical signals that can be sent back to the sending device.

Conclusion

The KSZ8841-16MVLI transceiver is a low-cost, small-size solution for ethernet applications. It is ideal for use in both LAN and automotive applications and supports 10 Mbps and 100 Mbps data transmission in both full-duplex and half-duplex modes. The transceiver is optimized to meet the 3.3V power standard and the symmetrical pin configuration makes it easy to use in different applications. It is a great solution for providing an interface between Ethernet physical wires and Ethernet equipment.
