The LAN9514I-JZX is a high performance Hi-speed USB 2.0 Hub with a 10/100 Ethernet controller. It contains an integrated USB 2.0 hub, four integrated downstream USB 2.0 PHYs, an integrated upstream USB 2.0 PHY, a 10/100 Ethernet PHY, a 10/100 Ethernet Controller, a TAP controller and an EEPROM controller. The downstream ports of the LAN9514i hub can be reordered or disabled in any sequence to support multiple platform designs’ with minimum effort. For any port that is disabled, it automatically reorders the remaining ports to match the USB host controller’s port numbering scheme. The integrated USB hub is fully compliant with the USB 2.0 Specification and will attach to an USB host as a full-speed hub or as a full-/high-speed hub. The hub supports low-speed, full-speed and high-speed (if operating as a High-Speed hub) downstream devices on all of the enabled downstream ports.
