BCM5464S
®
QUAD-PORT GIGABIT COPPER TRANSCEIVER WITH COPPER/FIBER
MEDIA INTERFACE
FEATURES
•
Four fully integrated 10BASE-T/100BASE-TX/1000BASE-T
Gigabit Ethernet transceivers
•
GMII, RGMII, SGMII, and SerDes MAC interface options
•
Copper or SerDes line interface options
SUMMARY OF BENEFITS
•
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
•
Reduced I/O pin requirements with RGMII (over 50%), SGMII
(over 75%), and SerDes (over 80%)
•
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
•
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
•
Fully compliant with IEEE 802.3, 802.3u, and 802.3ab
standards
•
0.13-micron CMOS—low-power and cost
•

•
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
