The BCM4401 10/100 Ethernet function incorporates a complete IEEE
802.3u compliant MAC and PHY. The MAC also supports 802.1p/Q,
802.3x, and management functions including RMON, Ethernet-like
MIB, and IEEE 802.3µ Ethernet MIB. The 10/100 PHY uses
Broadcom’s advanced Digi-PHY™ architecture for low power and
includes advanced power management. The 10/100 PHY also supports
auto-negotiation and HP Auto-MDIX functions to eliminate installation
errors.
The BCM4401KFB is pin-to-pin and software compatible with the
BCM5702 32-bit PCI Gigabit Ethernet controller. This provides a
seamless migration path from Fast Ethernet to Gigabit Ethernet
capabilities using a single PCB design.
By leveraging the NetXtremeTM BCM570x Gigabit Ethernet driver
architecture and the complete proven advanced software suite, the
BCM4401 10/100 solution brings enterprise-proven technology for
migrating business desktops and laptops to gigabit performance.
