CXD3220R
IEEE1394 Link/Transaction Layer Controller LSI for SBP-2
Description
The CXD3220R is a Link/Transaction Layer LSI
conforming to the IEEE1394 serial bus standard.
It is mainly used when connecting the IEEE1394
digital I/F to a storage device such as a hard disk,
DVD-ROM, CD-ROM or tape streamer.
Data transfer conforms to the SBP-2 protocol.
This LSI utilizes Apple Computer's Fire Wire
technology.
