Overview
The LAN9513/LAN9513i is a high performance Hi-Speed USB 2.0 hub with a 10/100 Ethernet
controller. With applications ranging from embedded systems, desktop PCs, notebook PCs, printers,
game consoles, and docking stations, the LAN9513/LAN9513i is targeted as a high performance, low
cost USB/Ethernet and USB/USB connectivity solution.
The LAN9513/LAN9513i contains an integrated USB 2.0 hub, three 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 a EEPROM controller. A block diagram of the LAN9513/LAN9513i is provided in
Figure 1.1.
The LAN9513/LAN9513i hub provides over 30 programmable features, including:
PortMap (also referred to as port remap) which provides flexible port mapping and disabling
sequences. The downstream ports of the LAN9513/LAN9513i hub can be reordered or disabled in any
sequence to support multiple platform designs’ with minimum effort. For any port that is disabled, the
LAN9513/LAN9513i automatically reorders the remaining ports to match the USB host controller’s port
numbering scheme.
PortSwap which adds per-port programmability to USB differential-pair pin locations. PortSwap allows
direct alignment of USB signals (D+/D-) to connectors avoiding uneven trace length or crossing of the
USB differential signals on the PCB.
PHYBoost which enables four programmable levels of USB signal drive strength in USB port
transceivers. PHYBoost attempts to restore USB signal integrity that has been compromised by system
level variables such as poor PCB layout, long cables, etc.
