BCM5424 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
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.
Requires no airflow or heatsink.
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, simplified
power supply, and multiple MAC interfaces.
