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.
The CXD3220R is a Link/Transaction Layer LSI that conforms to the IEEE‑1394 serial bus standard and supports SBP‑2 protocol for storage devices such as hard disks, DVD‑ROMs, and tape streamers. It offers bidirectional data transfer at 100 Mbps or 200 Mbps and includes a large FIFO for high‑speed data handling.
The document details pin configurations, electrical characteristics (DC and AC), input/output capacitance, and package dimensions. It also describes the asynchronous data pipe (ADP), link‑phy communication, and receive timing, providing designers with the necessary information to integrate the CXD3220R into their systems.
