LAN9514-JZX

The LAN9514-JZX is an USB 2.0 hub and 10/100 Ethernet Controller. The LAN9514 is specifically designed to provide system architects with a low-cost, power-efficient, small-footprint USB to Ethernet and multi-port USB connectivity solution. This contains a high 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. It offers Microchips highest level of USB 2.0 and 10/100 Ethernet compliance and interoperability. Additionally, this device simplifies system design by leveraging the existing USB stack and reducing the PCB footprint by up to 65% compared to discrete competitive solutions. USB-based networking technology offers a cost-effective and smart design alternative to traditional PCI/PCI-Express networking solutions due to the flexibility of routing and placement of Ethernet and USB connectivity ports.
