2250741-1 DRAWING

2.5G 4PPoE Circuit:

Key Features:

• Integrated Design: The most prominent feature is the integration of the RJ45 connector and the Ethernet magnetics (transformers and chokes) into a single, compact module.
• High-Speed Data Rate: It is designed to support 2.5GBASE-T Ethernet, ensuring high-speed network performance.
• High-Power PoE: The device supports 100W 4-Pair Power over Ethernet (4PPoE), allowing it to deliver significant power to connected devices like high-performance wireless access points, IP cameras, and LED lighting.
• Industry-Standard Compatibility: These ICMs are designed to be compatible with major Ethernet PHYs (physical layer devices) from manufacturers like Broadcom. They often use industry-standard footprints and pin-outs, which can make it easier to upgrade existing designs.
• Durability and Reliability: With features like a robust design and an operating temperature range suitable for various environments, these connectors are built for reliability. They are also typically 100% hi-pot tested in production.

Key Functions:

• Signal Conditioning: The integrated magnetics are crucial for maintaining signal integrity in high-speed data transmission. They help to ensure that the signals are clean and free from distortion.
• EMI Suppression: A primary function of the MagJack RJ45 2x2 is to suppress electromagnetic interference. The internal components, such as common mode chokes, are designed to handle both conducted and radiated noise, which is critical for meeting EMC (Electromagnetic Compatibility) requirements.
• Electrical Isolation: The magnetics provide galvanic isolation, which protects against short circuits and voltage spikes. This is a critical safety feature in networking equipment.
• Component and Space Reduction: By combining the connector and magnetics, the ICM reduces the number of components on the printed circuit board (PCB), which in turn saves valuable board space and can simplify the design and assembly process.
• Power Delivery (PoE): The module facilitates the transmission of power over the Ethernet cable, serving as either Power Sourcing Equipment (PSE) or a Powered Device (PD).
