BCM54991ELMA0KFEBG Description

The BCM54991ELMA0KFEBG is an advanced 8x8 Single 2.5G PHY Transceiver from Broadcom Limited, designed for high-performance networking applications. This IC integrates MAC (Media Access Control) functionality with a 2.5G Ethernet PHY, enabling seamless data transmission and reception in demanding environments. Packaged in a tray format, it complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 3 (168 hours), ensuring reliability in assembly and operation. Although marked as Obsolete (ECCN: OBSOLETE), it remains a robust solution for legacy systems requiring stable PHY-layer performance.

BCM54991ELMA0KFEBG Features

• High-Speed PHY Layer: Supports 2.5G Ethernet with 8x8 single-lane configuration, ideal for bandwidth-intensive applications.
• Integrated MAC Functionality: Reduces external component count, simplifying system design and lowering BOM costs.
• RoHS3 Compliance: Environmentally friendly, meeting global regulatory standards.
• Industrial-Grade Reliability: MSL 3 rating ensures durability in varied operating conditions.
• Low-Latency Operation: Optimized for real-time data processing in networking hardware.

Compared to similar transceivers, the BCM54991ELMA0KFEBG stands out for its high port density (8x8) and 2.5G support, making it suitable for upgraded legacy systems where newer PHYs may not be backward-compatible.

BCM54991ELMA0KFEBG Applications

• Enterprise Switches: Enables multi-port 2.5G connectivity in data centers and enterprise networks.
• Industrial Networking: Used in ruggedized equipment requiring stable PHY-layer performance.
• Telecom Infrastructure: Supports high-speed backhaul and fronthaul applications.
