The BCM5700 is a high-performance 10/100/1000BASE-T
Ethernet LAN controller optimized for NIC and LOM
applications. The BCM5700 is a highly-integrated solution
combining 10/100/1000BASE-T IEEE 802.3 compliant media
access controller (MAC), PCI and PCI-X bus interfaces, and
on-chip buffer memory in a single device. The BCM5700 is
fabricated in a low voltage 1.8V CMOS process, providing a
low-power system solution. Combine the BCM5700 with the
BCM5401 (or later) single-chip Gigabit Ethernet transceiver to
achieve a complete NIC or LOM solution for
10/100/1000BASE-T Ethernet.
The BCM5700 includes a 10/100/1000 Mbps Ethernet MAC with
full/half-duplex capability at all speeds. The MAC interacts with
the external transciever via the GMII in 1000BASE-T mode, the
MII in 10/100BASE-T mode, and the TBI serial interface in
1000BASE-SX/1000BASE-FX mode. Support for the following
802.3 packet tagging functions is featured in the MAC: VLAN
tagging, layer 2 priority encoding, link aggregation, and full-duplex
flow control.
The device provides both PCI v2.2, 32/64-bit, 33/66-MHz and
PCI-X v1.0, 133-MHz, host interfaces. The BCM5700 includes
a 96 KB on-chip buffer memory for stand-alone operation, and
optionally supports up to 16 MB of external memory. Dual on-
chip high-performance processors enable many custom frame
processing features, including TCP segmentation.
