MVTX2604
Managed 24-Port 10/100 Mb + 2 Port 1 Gb
Ethernet Switch
Data Sheet
Features
• Integrated Single-Chip 10/100/1000 Mbps
Ethernet Switch
• 24 10/100 Mbps Autosensing, Fast Ethernet
Ports with RMII or Serial Interface (7WS). Each
port can independently use one of the two
interfaces
• 2 Gigabit Ports with GMII, PCS, 10/100 and
stacking (2 G per port) interface options per port
• Stacking port supports hot swap in managed
configuration
• Supports 8/16-bit CPU interface in managed
mode
• Serial interface in unmanaged mode
• Supports two Frame Buffer Memory domains with
SRAM at 100 MHz
• Supports memory size 2 MB, or 4 MB
• For 24 + 2, two SRAM domains (2 MB or 4 MB) are
required.
• For 24 + 2 stacking (2 G per stacking port), two ZBT
domains (2 MB or 4 MB) are required
• Applies centralized shared memory architecture
• Up to 64 K MAC addresses
• Maximum throughput is 6.4 Gbps non-blocking
• High performance packet forwarding (19.047 M
packets per second) at full wire speed

MVTX2604AG 553 Pin HSBGA
-40°C to 85°C
• Provides port based and ID tagged VLAN
support (IEEE 802.1Q), up to 255 VLANs
• Supports IP Multicast with IGMP snooping
• Supports spanning tree with CPU, on per port or
per VLAN basis
• Packet Filtering and Port Security
• Static address filtering for source and/or destination
MAC
• Static MAC address not subject to aging
• Secure mode freezes MAC address learning
Each port may independently use this mode
• Full Duplex Ethernet IEEE 802.3x Flow Control
• Backpressure flow control for Half Duplex ports
• Supports Ethernet multicasting and broadcasting
and flooding control
• Supports per-system option to enable flow
control for best effort frames even on QoS-
enabled ports
