BCM5464S
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
Flexibility for copper or fiber applications
Provides compatibility with IEEE standard devices operating
at 10, 100, and 1000 Mbps at half-duplex and full-duplex
Requires no air flow or heat sink
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 4kV 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
routing high density solutions
(over 75%), and SerDes (over 80%)
required by the RGMII specification
required to interface to the PHY
