Additional Details

The KSZ9031RNXIA TR operates on a 3.3V power supply. The operating temperature range is typically specified for industrial or commercial applications. The package type is usually a QFN (Quad Flat No-leads) or similar, designed for surface mounting. It requires external magnetics for connecting to the Ethernet cable. The "TR" suffix usually indicates tape and reel packaging for automated assembly. This transceiver is commonly used in applications where reliable and high-speed Ethernet connectivity is essential.
