MB86615

FUJITSU SEMICONDUCTOR DATA SHEET DS04-22002-1E ASSP Communication Control IEEE 1394 Bus Controller (for DVC) 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. s FEATURES Compatible with IEEE 1394 high-performance serial bus standards Physical layer and link layer integrated on one chip 1 cable ports Supports s100 transfer speed (98.304 Mbit/sec) 3.3V single power supply operation Built-in PLL (for crystal oscillator) for internal clock signal generation Power saving modes 1) Forced sleep mode at instruction from MPU 2) Automatic sleep mode for non-connected ports Header and data units automatically separated at receiving and automatic packetizing for sending Suppo...
