Description

The MVTX2602 is a high density, low cost, high performance, non-blocking Ethernet switch chip. A single chip

provides 24 ports at 10/100 Mbps and a CPU interface for managed and unmanaged switch applications.

The chip supports up to 64 K MAC addresses and up to 255 port-based Virtual LANs (VLANs). The centralized

shared memory architecture permits a very high performance packet forwarding rate at up to 3.571M packets per

second at full wire speed. The chip is optimized to provide low-cost, high-performance workgroup switching.

The Frame Buffer Memory domains utilize cost-effective, high-performance synchronous SRAM with aggregate

bandwidth of 6.4 Gbps to support full wire speed on all ports simultaneously.

With delay bounded, strict priority, and/or WFQ transmission scheduling, and WRED dropping schemes, the

MVTX2602 provides powerful QoS functions for various multimedia and mission-critical applications. The chip

provides 4 transmission priorities and 2 levels of dropping precedence. Each packet is assigned a transmission

priority and dropping precedence based on the VLAN priority field in a VLAN tagged frame, or the DS/TOS field, or

the UDP/TCP logical port fields in IP packets. The MVTX2602 recognizes a total of 16 UDP/TCP logical ports, 8

hard-wired and 8 programmable (including one programmable range).

The MVTX2602 supports 2 groups of port trunking/load sharing. Each 10/100 group can contain up to 4 ports. Port

trunking/load sharing can be used to group ports between interlinked switches to increase the effective network

bandwidth.

In half-duplex mode, all ports support backpressure flow control to minimize the risk of losing data during long

activity bursts. In full-duplex mode, IEEE 802.3x flow control is provided. The MVTX2602 also supports a per-

system option to enable flow control for best effort frames, even on QoS-enabled ports.

Statistical information for SNMP and the Remote Monitoring Management Information Base (RMON MIB) are

collected independently for all ports. Access to these statistical counters/registers is provided via the CPU interface.

SNMP Management frames can be received and transmitted via the CPU interface creating a complete network

management solution.

The MVTX2602 is fabricated using 0.25 micron technology. Inputs however, are 3.3 V tolerant, and the outputs are

capable of directly interfacing to LVTTL levels. The MVTX2602 is packaged in a 553-pin Ball Grid Array package.
