Bcm84886 Exclusive [new] -
Broadcom BCM84886
The is a high-performance, dual-port Ethernet transceiver designed to bridge the gap between legacy infrastructure and modern high-speed networking requirements. As part of Broadcom's extensive PHY and PoE portfolio , this CMOS device enables multi-rate connectivity over standard twisted-pair copper cabling, making it a cornerstone for enterprise and data center upgrades. Key Specifications and Connectivity
Broadcom positions the BCM84886 for use in critical networking infrastructure, including: BCM84886 - Broadcom Inc. bcm84886 exclusive
Note to user
: If you meant a different model (e.g., BCM84886 – possibly a misprint for BCM84888 or BCM84891), please provide a correction. For an actual Broadcom confidential datasheet, you must sign an NDA and request via your Broadcom sales representative. Octal Density : 8 independent PHYs in a
- Octal Density: 8 independent PHYs in a single 35×35mm FCBGA package – highest port density for 10GBase-T.
- Auto-Negotiation (Clause 73) with Next Page support for 2.5G/5G NBASE-T.
- Low-Power Idle (LPI) per IEEE 802.3az (Energy-Efficient Ethernet) – reduces power by >70% during idle.
- Digital Signal Processor (DSP) with adaptive equalization and echo/NEXT cancellation enabling 100m reach on Cat6a.
- MACsec (Securities) offload on select variants (BCM84888 includes basic version; full MACsec on BCM84890).

Conclusion: The Silent Workhorse
Are you designing for Multi-Gigabit speeds? What are your biggest challenges with PHY power consumption? Let’s discuss in the comments.
high-density, 8-port 10GBASE-T/5GBASE-T/2.5GBASE-T/1000BASE-T/100BASE-TX Ethernet transceiver
Before we discuss exclusivity, we must understand the silicon. The BCM84888 is a designed by Broadcom. It is built on a 28nm CMOS process (or similar advanced node), allowing it to support 10G speeds over traditional Category 6a copper cabling for distances up to 100 meters.
: Compatible with XFI, USXGMII, and various multi-gigabit interfaces (e.g., 5000BASE-X and 2500BASE-X). Time Stamping
