Description
The MDS1903URH is a fully integrated 5 port Ethernet switch designed for unmanaged switch applications. It provides features that are normally not associated with plug-and-play technology, without the need for an external processor.
Specifications and features
- 4 10/100 Mbps auto-negotiating RMII ports
- 1 10/100 Mbps auto-negotiating MII/serial port (Port 4) that can be used as a WAN uplink or as a 5th port
- External I2C EEPROM for power-up configuration (default mode allows operation without external EEPROM)
- Up to 4 port-based VLANs
- Full wire-speed layer 2 switching on all ports (up to 1.448 M packets per second)
- Internal 1 k MAC address table with auto address learning and aging
- Leading edge QoS capabilities provided based on 802.1p and IP TOS/DS field, with 2 queues per output port and packet scheduling based on Weighted RoundRobin (WRR) and Weighted Random Early Detection/Drop (WRED)
- Supports both Full/Half duplex ports
- Supports external parallel port for configuration updates
- Port 3 can be used to mirror traffic from the other 3 ports (0-2)
- Provides port-based prioritization of packets on up to 2 ports (0-1)
- Ports 0 & 1 can be trunked to provide a 200 Mbps link to another switch or server
- Utilizes a single low-cost external Pipelined, SyncBurst SRAM (SBRAM) for buffer memory (256 k bytes or 512 k bytes (1 chip))
- Flow Control capabilities, providing back pressure for half duplex and 802.3x flow control for full duplex
- Special power-saving mode for inactive ports
- Ability to support WinSock2.0 and Windows2000 smart applications
- Transmit delay control capabilities, providing maximum delay guarantee (<1 ms) and supporting mixed voice-data networks
- Optimized pin-out for easy board layoutApplication Scenarios
The MDS1903URH is ideal for various unmanaged switch applications, especially in environments where cost is a priority. It is suitable for small offices, home networks, and other setups that require a reliable and cost-effective Ethernet switch.
