KSZ9021RNI Description

Short technical summary and product information.

The KSZ9021RNI from Microchip Technology is a single-chip, triple-speed Ethernet physical-layer transceiver designed for the transmission and reception of data. It supports 10BASE-T, 100BASE-TX, and 1000BASE-T standards over standard CAT-5 unshielded twisted pair cable.

This transceiver provides the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to MACs in Gigabit Ethernet processors and switches, enabling data transfer at 10/100/1000 Mbps. It operates with supply voltages of 1.8V, 2.5V, and 3.3V and is rated for an operating temperature range of -40°C to 85°C.

The KSZ9021RNI is housed in a 48-VFQFN Exposed Pad package and is designed for surface mount applications. It offers features such as auto-negotiation for selecting the highest link-up speed and duplex mode, on-chip termination resistors, and an on-chip LDO controller for single 3.3V supply operation.
