MB86615

s DESCRIPTION

The MB86615 is 1394 serial bus controller compatible with the IEEE 1394 “FireWire” standard (IEEE Standard

1394-1995). One built-in port plus a differential transceiver and comparator are provided to enable formation of

networks in a 1394 cable environment. The MB86615 supports s100 data transfer speeds.

By integrating the physical layer and link layer on one chip, The MB86615 is designed to reduce mounting area

as well as power consumption.

The MB86615 has an exclusive data port for isochronous transfer, provides automatic packetizing for sending

and separation of header and data units at receiving, and is optimized for continuity of transfer processing.

The MB86615 supports DVC AV/C protocols, and includes the necessary built-in automatic operations and

CSR’s for providing the necessary operations for DVC data transfer.
