Forward compatibility to next-generation 28nm process ensures scalability and preserves customer investments, eliminating the need to redesign the board when moving to the next node. 

The BCM84848 PHY features Energy Efficient Ethernet (EEE) technology for multiple speeds including 10GBASE-T, 1000BASE-T and 100BASE-TX, expanding energy savings throughout the network by automatically reducing power consumption during periods of no activity. 

Key Features:

  • Robust operation over 100 meter Category 6a cables with industry standard 4-pair magnetics
  • Lower total cost of ownership with auto-negotiation that reduces system administration costs
  • IEEE 1588v2 with one-step timestamp insertion provides high accuracy timing
  • IEEE 802.1ae MACsec provides link layer security
  • Supports multiple speeds including 10GBASE-T, 1000BASE-T and 100BASE-TX with EEE supported on all three speeds

The BCM84848 PHY is now sampling with production volume slated for the first quarter of 2013.
