The KSZ8721BL is an Ethernet physical layer transceiver integrated circuit (IC) that operates at high speeds for applications in industrial and automotive environments. It is part of the KSZ8721 series offered by Microchip Technology.
One key feature of the KSZ8721BL is its support for 10/100 Mbps Ethernet communication. It is compliant with the IEEE 802.3 standard, making it compatible with various network devices. The IC also supports both full-duplex and half-duplex modes, providing flexibility in network configurations.
To ensure reliable and robust communication, the KSZ8721BL implements various advanced features. It supports Auto-Negotiation, which allows devices to automatically detect and establish the best possible connection speed and duplex mode. It also features Auto-MDIX, eliminating the need for crossover cables by automatically sensing and adapting to the appropriate cable type.
The KSZ8721BL incorporates energy-saving features, making it suitable for applications with power-constrained environments. It supports both Energy-Efficient Ethernet (EEE) and Wake-on-LAN (WoL) functionality, enabling power-saving modes during periods of low network activity and allowing remote device wake-up.
In terms of interface options, the KSZ8721BL offers a choice of either a standard Media Independent Interface (MII) or Reduced Media Independent Interface (RMII)
