BCM5414 System Diagram
•
Low-power, quad-port integration enables single-row,
high port density switches.
•
Lowers system costs by eliminating PCB layers required for
routing high density solutions
•
1.5V or 1.8V HSTL signal levels eliminate the need for 3.3V
power supply, lowering system cost and simplifying design
•
Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification.
•
Lowers MAC/switch costs by reducing the number of pins
required to interface to the PHY.
•
Provides compatibility with IEEE standard devices
operating at 10, 100, and 1000 Mbps at half- and full-
duplex.
•
Reduces design constraints in high-density
applications that have higher EMI emissions.
•
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.
•
Supports jumbo packets for wider range of packet
protocol compatibility.
•
Ease of manufacturing with JTAG support and
simplified power supply.
