Overview
The BCM53101EIMLG is a seven-port managed 10/100 Ethernet switch fabricated using a 65 nm LP process. It integrates five 10/100 MACs with five 10/100 PHYs, one 10/100 MAC via MII/RvMII/RMII, and one 10/100/1000 MAC via RGMII/MII/RvMII/RMII. The device supports 2K MAC addresses, 4K-entry VLANs, and four CoS queues for QoS. Power consumption is less than 0.7W at full power, utilizing 1.2V core and 2.5V/3.3V I/O voltages.
Feature Summary
- Integrates five Fast Ethernet transceivers with on-chip MACs for simplified PCB design
- Supports Layer 2+ features including 802.1Q VLAN, IGMP/MLD snooping, and IEEE 802.1x security
- Enables BroadSync HD for Audio Video Bridging traffic control and time synchronization
- Incorporates green modes such as auto-power down, sleep, and deep sleep to minimize energy usage
Applications
- Next-generation six Fast Ethernet plus one Gigabit Ethernet switches
- Managed industrial and enterprise network switches
- Networked electronic devices requiring guaranteed bandwidth and latency for audio/video traffic
Procurement Notes
Verify the specific ordering suffix against official Broadcom documentation to confirm package type and temperature range. Confirm RoHS compliance status through the manufacturer's product compliance database prior to finalizing procurement orders.
Selection Notes
Select this component when designing cost-effective managed switches requiring integrated PHYs and L2+ features. Ensure the application utilizes the 65 nm LP process benefits for low power. Verify interface compatibility for the GMAC port if connecting to an external CPU via RGMII or MII.
Part Context
The BCM53101 serves as a feature-enhanced successor to the BCM5325E RoboSwitch. It combines packet buffers, PHY transceivers, MACs, address management, and a non-blocking switch fabric into a single chip. This integration reduces system complexity and lowers overall interoperability risks compared to discrete solutions.
Replacement Considerations
The BCM5325E is identified as the predecessor model in official documentation. Verify functional equivalence and pinout compatibility before considering substitution.
