PHY 1-CH 10Gbps 676-Pin FBGA

The Broadcom BCM84844 is a complete quad 100BASE-TX, 1000BASE-T and 10GBASE-T solution operating at 100m over CAT6a UTP cable. The BCM84844 is pin-compatible with the earlier BCM84834 device, offering lower power while adding Energy Efficient Ethernet (EEE) for 1000BASE-T and 100BASE-TX, in addition to 10GBASE-T. Optional Adaptive Voltage Scaling (AVS) delivers a low power solution while enabling a low cost implementation. The BCM84844 is based on a highly advanced digital signal processor architecture to enable robust operations over worst case UTP cables.

• Highly integrated four-port 10GBASE-T Ethernet transceiver.
• Supports multiple speeds: 10GBASE-T as well as 100BASE-TX and 1000BASE-T.
