PL-2501
Hi-Speed USB Host to Host Bridge Controller
OVERVIEW
The PL-2501 is a single chip Hi-Speed USB Host-to-Host Bridge Controller. With PL-2501 embedded cable, users can
quickly transfer large amount and large size of files directly from one PC to another. Also it’s useful for computer data
backup/restore, synchronization or file sharing. Additionally, the chip enables two or more Hi-Speed USB or USB1.1
equipped PCs to connect to each other using USB ports as a network. Since Hi-Speed USB extends the speed up to 480
Mbps – 40 times more than previous USB, the network constructed by PL-2501 has data rates almost 5 times faster than
a conventional 100BT Ethernet network. Implemented with remote NDIS, users can easily build up this network at a
turbo speed without the troubled installation of drivers and add-on network interface cards.
