Product Details

__

The FW323 is the Agere Systems Inc. implementation of a high-performance, PCI bus-based open host controller for implementation of IEEE 1394a-2000 compliant systems and devices. Link-layer functions are handled by the FW323, utilizing the on-chip 1394a-2000 compliant link core and physical layer core. A high- performance and cost effective solution for connecting and servicing multiple IEEE 1394 (both 1394-1995 and 1394a-2000) peripheral devices can be realized.

■ 1394a-2000 PHY core:
— Compliant with IEEE ® 1394a-2000, Standard for a High Performance Serial Bus (Supplement)
— Provides three fully compliant cable ports, each supporting 400 Mbits/s, 200 Mbits/s, and 100 Mbits/s traffic
— Supports extended BIAS_HANDSHAKE time for enhanced interoperability with camcorders
— While unpowered and connected to the bus, will not drive TPBIAS on a connected port even if receiving incoming bias voltage on that port
— Does not require external filter capacitor for PLL
— Supports PHY core-link interface initialization and reset
— Supports link-on as a part of the internal PHY core-link interface
— 25 MHz crystal oscillator and internal PLL provide transmit/receive data at 100 Mbits/s, 200 Mbits/s, and 400 Mbits/s, and internal link-layer controller clock at 50 MHz
— Interoperable across 1394 cable with 1394 physical layers (PHY core) using 5 V supplies
— Node power-class information signaling for system power management
— Supports ack-accelerated arbitration and fly-by concatenation
— Supports arbitrated short bus reset to improve utilization of the bus
— Fully supports suspend/resume
— Supports connection debounce
— Supports multispeed packet concatenation
— Supports PHY pinging and remote PHY access packets
— Reports cable power fail interrupt when voltage at CPS pin falls below 7.5 V
— Separate cable bias and driver termination voltage supply for each port
■ Link:
— Cycle master and isochronous resource manager capable
— Supports 1394a-2000 acceleration features
