FM2000 Series - 10G L2 Ethernet Switch Chip Family
The FocalPoint FM2000 Series of fully-integrated single-chip wire-speed Ethernet switch chips leads the market in low-latency intelligent switching, delivering cut-through latency as low as 200ns. With robust layer-2 switching capabilities and the ubiquity of Ethernet, the FM2000 Series fits comfortably in a number of existing and emerging applications. And, with the unprecedented level of integration and a variety of device variants, FocalPoint removes the cost barrier for rapid and far-reaching deployment of 10G Ethernet.

Notes:
- The ports identified as "10G XAUI, SGMII" can be independently configured to operate at 10G rate (XAUI or CX4), or at 10M, 100M, 1G, and 2.5G rates (using the SGMII standard).
- The ports identified as "SGMII" can be independently configured to operate at 10M, 100M, 1G, and 2.5G rates, using the SGMII standard.
