BCM5700
Gigabit PCI MAC
10/100/1000BASE-T Network Interface Card
•
Provides interoperability with IEEE standard devices
operating at 10, 100, and 1000 Mbps at half- and full-
duplex.
•
Lowers system cost and reduces solution footprint.
•
Requires no airflow or heatsink.
•
Provides compliance with PCI 2.2 and PC99/PC2000.
•
Reduces system design constraints to meet EMI
emissions standards.
•
Automatically configures the link to support the
highest possible speed based on link partner capability
and characteristics of the channel.
•
Cable diagnostic function characterizes cable plant
condition and immediately indicates cabling issues.
•
Prevents erroneous equipment return due to bad cable plants.
•
Prevents manufacturing fall-out due to bad cable plants.
•
High CESD tolerance prevents equipment damage and
return.
•
Operates with larger packets for wider range of packet
protocol support and improved efficiency.
•
Ease of manufacturing with JTAG support, simplified
power supply, and multiple MAC interfaces.
•
Simplifies system and board design.
•
RGMII/RTBI reduces I/O pin requirement over GMII and TBI
by more than 50%.
