MB86612
s DESCRIPTION
The MB86612 is 1394 serial bus controller exclusively for MPEG and DVC data transfer, compatible with the
IEEE 1394 “FireWire” standard (IEEE Standard 1394-1995). Two built-in ports plus a differential transceiver and
comparator are provided to enable formation of networks in a 1394 cable environment. The MB86612 supports
s100 data transfer speeds.
By integrating the physical layer and link layer on one chip, The MB86612 is designed to reduce mounting area
as well as power consumption.
The MB86612 has an exclusive data port for isochronous transfer, provides automatic packetizing and separation
of header and data units, and is optimized for continuity of transfer processing.
The MB86612 supports MPEG and DVC AV/C protocols, and includes the necessary built-in automatic
operations and CSR’s for providing the necessary operations for MPEG and DVC data transfer.
