It is well suited for interfacing between 25MHz systems, such as microcontrollers, DSPs, and FPGAs, to Gigabit Ethernet networks. With its ultra-low latency and very low power consumption, it offers a reliable connection for time-sensitive applications.

The PI3HDX1204B1ZHIEX is used in a wide range of industries, including industrial automation, medical, automotive, and video streaming. The device is ideally suited for Ethernet-connected systems requiring a high-speed, low-latency connection. Its support for the IEEE 802.3bz standard ensures compatibility with existing systems, making it perfect for use in retrofitting existing systems.

Working Principle

The PI3HDX1204B1ZHIEX follows the two-step process for data transmission, as specified by the IEEE 802.3bz standard. The first step is the Half Duplex mode, wherein the device transmits and receives data at the same time. It then switches to Full Duplex mode to transmit data in both directions simultaneously. In Half Duplex mode, the device transmits data at the speed of its half-duplex data link rate, then waits for a response before it can start sending data again. In Full Duplex mode, the device is capable of transmitting at twice the speed of its half-duplex data link rate.

The PI3HDX1204B1ZHIEX also provides error checking and correction when receiving data, and can detect and drop any frames that are incorrect or have been modified. This helps ensure that only valid data is transferred, ensuring reliable connections. The device also supports a number of power saving features, including the ability to enter a low-power mode when not in use.

The PI3HDX1204B1ZHIEX is an ideal solution for systems requiring a reliable and cost-effective Gigabit Ethernet interface. With its low latency, low power consumption, and support for the IEEE 802.3bz standard, it provides a reliable connection for time-sensitive applications, making it perfect for a wide range of industries.
