Evaluation and Demonstration Boards and Kits

Evaluation and demonstration boards and kits serve a vital role in product development and testing. Through development boards and kits, designers can experiment with various components, simulate different circuit operations, and verify the performance and features of actual or prototype products. This article will discuss the application field and working principle of KSZ8863RLL-EVAL, one such evaluation board.

Overview of KSZ8863RLL-EVAL

The Micrel KSZ8863RLL is a low-power switch with an integrated 2-port Ethernet PHY designed for power over Ethernet (PoE) applications. The evaluation board, KSZ8863RLL-EVAL, enables users to evaluate the features and functionality of the KSZ8863RLL switch. It is integrated with a wide range of features and functionalities such as PoE, SMI/GPIO ports, JTAG/SPI/UART interfaces, I2C PWM, and USB connections, making it a comprehensive platform for the development and evaluation of a broad range of Ethernet-enabled products.

Application Fields of KSZ8863RLL-EVAL

The KSZ8863RLL-EVAL evaluation board has a wide range of applications in the PoE field. It is specifically designed for the evaluation and development of embedded Power-over-Ethernet (PoE) products. It supports the IEEE 802.3 PoE standard with its four-port integrated 10/100 Ethernet switch with two PoE ports. In addition, its two SMI/GPIO ports allow for communication between the embedded processors, MAC and the evaluation board.

The KSZ8863RLL-EVAL evaluation board is ideal for embedded network-based systems, IoT devices, surveillance and security system, and many other applications which require PoE support. It is also suitable for development of other types of Ethernet-enabled products such as connected smart homes, sensor and motor control, industrial and kitchen appliances, consumer electronics, and other wearable and wireless devices.

Working Principle of KSZ8863RLL-EVAL

The KSZ8863RLL-EVAL evaluation board is based on the KSZ8863RLL switch MCU, which is a low-power 2-port Ethernet switch controller that implements the IEEE 802.3 10Base-T, 100Base-TX, and PoE standards. The switch contains a Media Access Controller (MAC), Switch Serial Management Interface (SMI) and four 10/100-megabit auto-negotiation ports. The SMI operates as the control plane for the switch and provides an interface to external memory and other applications.

The KSZ8863RLL-EVAL evaluation board has two gigabit Ethernet ports and four 10/100 Ethernet ports. It supports PoE power and data through its two PoE ports and can detect data and power at each port. It can also detect and control PoE devices. The board also provides an SMI interface which integrates the control plane for the switch and provides an interface for external memory and applications.

The board is also equipped with various interfaces for connecting peripheral devices such as USB, UART, SPI, JTAG and I₂C. The USB interface allows for transferring data and programming devices while the UART interface can be used for communication with bi-directional serial ports. The SPI and JTAG interfaces can be used for debugging and programming of the switch and the I₂C bus is used for communication with a variety of external peripherals. The board also supports a PWM port for controlling an external device.

The KSZ8863RLL-EVAL also provides a Diagnostics mode which can be used to test and verify the functionality of the evaluation board and the switch MCU. The board also supports various software tools for creating and testing various applications.

Conclusion

The Micrel KSZ8863RLL is a low-power switch integrated with a 2-port Ethernet PHY designed specifically for PoE applications. The KSZ8863RLL-EVAL is an evaluation board designed for the evaluation and development of embedded Power-over-Ethernet (PoE) products. It is equipped with a range of features such as PoE, SMI/GPIO ports, JTAG/SPI/UART interfaces, and I2C PWM, making it a comprehensive platform for the evaluation and development of Ethernet-enabled products.
