BCM5464
Low-power, quad-port integration enables single-row,
high port density switches
• Lowers system costs by eliminating PCB layers required for
• Reduced I/O pin requirements with RGMII (over 50%), SGMII
• Clock timing can be adjusted to eliminate board trace delays
• Lowers MAC/switch costs by reducing the number of pins
Provides compatibility with IEEE standard devices
operating at 10, 100, and 1000 Mbps at at half-duplex
and full-duplex
Requires no airflow or heatsink
Lowers system BOM cost and simplifies system design
Eases system level debug
Enables use of low cost magnetics, even in high density
(48+) designs
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
Over 4 kV of 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
S U M M A R Y
routing high density solutions
(over 75%), and SerDes (over 80%)
required by the RGMII specification
required to interface to the PHY
