VSC2800 OctalMAC Fast Ethernet Controller
GENERAL DESCRIPTION: Seamless Integration with the IQ2000TM Family of NPUs The VSC2800 OctalMAC is a single chip high-speed packet concentrator designed to communicate via the FOCUS16 Interface with Vitesse's IQ2000TM Architecture. The OctalMAC combines high performance packet transfer features, comprehensive packet-handling capabilities, and automated statistics gathering for network management support. The OctalMAC provides a cost effective solution with excellent performance when used in conjunction with Vitesse's IQ2000 family of network processors. The integrated features of the OctalMAC offload the functions of the Network Processor while simplifying the design and lowering overall design costs. Vitesse's OctalMAC allows the network processor to concentrate on providing next generation services such as DiffServ and IPSec while delivering wire-rate performance. The OctalMAC also reduces host processing requirements by providing automated gathering of RMON and SNMP network management statistics. FOCUS16 The FOCUS Interface is a high performance, point-to-point interface designed to efficiently transfer packet data between Vitesse's IQ2000 family of network processors and peripheral I/O interface devices or interconnect fabrics. In addition to data transfer, the FOCUS Interface supports in band access to statistics as well as command and status information.
Specifications: Interfaces (Port Selectable) · Eight 10/100 MII Ports or · Eight 10.100 RMII Ports Support for IEEE Standards · Compliant with 802.3 (Ethernet), 802.3µ, 802.3x · Supports VLAN Based Standards: - 802.1d (MAC Bridges) - 802.1q (VLAN) - 802.3ac (Frame Extensions) Environmental · 2.5V Core, 3.3V I/O, 5V Tolerant · 0.6W (Max) · 208 Pin PQFP Applications: · High Port density Applications
Functionality The device incorporates eight internal 10/100 Ethernet Media Access Controllers (MACs), a single FOCUS16 Interface, and a MII management controller. Each MAC is dual speed and capable of half-duplex and full-duplex operation. Flow control is provided in the half-duplex mode with backpressure. In fullduplex mode, 802.3x frame-based flow control is supported. Each MAC is 802.3 compliant and supports maximum frame sizes up to 1536 bytes. The device also supports jumbo packets up to 64Kbytes. The eight Ethernet MACs interface directly to commercially available PHY devices using either MII or RMII. The OctalMAC can be configured on a per port basis to support a mixture of MII and RMII PHY devices. The OctalMAC includes automated statistics gathering on a per port basis for layer management, SNMP, and RMON support. The OctalMAC automatically counts the packet type, length, errors, and other packet characteristics for both transmit and receive. A total of 48 statistical counters per port are internally maintained for use by system software in support of the various Management Information Bases (MIBs) required by network systems.
FOCUS16 Interface · 1.28 Gb/s Full Duplex bandwidth · Eight Data Channels and One Control Channel Per Interface · 36 Pin Interface Support for Statistics Management · Supports 26 Receive Statistics Per Port · Supports 22 Transmit Statistics Per Port · Supports IETF RECs: - 1573 (MIB-II Interfaces), - 1643/1650 (Ether MIB Statistics), - 1757 (RMON MIB) · 0° - 70° Celsius Operating Temp
