Overview
The LAN9514-JZX-TR is a highly integrated USB 2.0 to 10/100 Ethernet controller produced by Microchip Technology. This device is designed to provide a low-cost, power-efficient solution for USB to Ethernet and multi-port USB connectivity in a single package. It combines a Hi-Speed USB 2.0 hub with four fully-integrated downstream USB 2.0 PHYs, an integrated upstream USB 2.0 PHY, a 10/100 Ethernet MAC/PHY controller, and an EEPROM controller. This integration simplifies system design and reduces the PCB footprint significantly compared to discrete solutions.
