BCM5702 pdf datasheet (10/100/

The BCM5702 is a fully-integrated 10/100/1000BASE-T Gigabit
Ethernet media access control and physical layer transceiver solution for
high-performance network applications. The BCM5702 is a highlyintegrated
solution combining a triple-speed, IEEE 802.3 compliant
media access controller (MAC), PCI bus interfaces, an on-chip buffer
memory, and an integrated physical layer transceiver in a single device.
The BCM5702 is fabricated in a low-voltage 0.13-μm CMOS process,
providing a low-power system solution. By itself the BCM5702 provides
a complete, single-chip, Gigabit Ethernet NIC or LOM solution.
The BCM5702 includes a 10/100/1000-Mbps Ethernet MAC with full/
half-duplex capability at all speeds and a 10/100/1000 copper PHY.
Support for the following 802.3 functions is featured in the MAC: VLAN
tagging, layer 2 priority encoding, link aggregation, and full-duplex flow
control.
The BCM5702 provides a PCI v2.2 bus interface. It also provides large
on-chip buffer memory for stand-alone operation. Dual, on-chip, highperformance
processors enable custom frame processing features,
including TCP segmentation.
