BCM5700 FEATURES
BCM5700 10/100/1000 PCI-X NIC Reference Design
•Features wire speed operation at all speeds.
•The BCM5700 is ideal for new high speed Network Interface
Cards (NIC) and LAN on Motherboard (LOM) applications,
while maintaining backward compatibility with today’s
networks.
•Support for both the PCI 2.2 and PCI-X standard enables
the BCM5700 to run in any PCI-based or PCI-X systems.
•The ultra-deep on-chip packet buffer allows the BCM5700 to
continuously transmit and receive at high speeds in systems
where the PCI/PCI-X bus is shared with other devices.
•On-chip CPUs perform advanced functions and allow the
BCM5700 to evolve with new standards. The CPUs also
provide advanced packet parsing capabilities, making the
BCM5700 an OSI L4 protocol aware device, providing many
advanced features and offloads.
•Advanced offload features promote high throughput, while
minimizing host CPU utilization.
•Combined with the BCM5401 and newer Broadcom
10/100/1000BASE-T PHYs, the BCM5700 supports ACPI-
compliant Wake on LAN implementations.
•Additional manageability features enable NIC and LOM
designs to comply with relevant manageability standards for
server and desktop applications.
•Provides low power operation – 0.18u advanced process
technology, combined with programmable power
management.

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 interfaces to the
external transciever via the GMII in 1000BASE-T mode, the MII in
10/100BASE-T mode, and 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.
