The Oxford OXUF924DSA/B is a high performance solution for bridging between SATA disks

and USB2.0, FireWire400, and FireWire800 (DSB only). The chip is used for creating external

storage solutions which connect to a PC & Apple Mac via the USB2.0 or FireWire port.

The UF924DSA/B contains a full USB2.0 link/Phy & FireWire link, minimising external components.
