Low-power quad-port integration enables single-row, high port
density switches
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
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
- 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
- Prevents erroneous equipment return due to bad cable plants
- Prevents manufacturing fall-out due to bad cable plants

... IEEE requirements for echo, NEXT, and FEXT. Low-power is key to implementing high-density Gigabit switches, and the BCM5464SR has the lowest power in the industry at less than 750 mW per port. In addition, the BCM5464SR has extremely low EMI emissions, which reduces the design constraints required to meet EMI radiation specifications ...
