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
• 1.5V or 1.8V HSTL signal levels eliminate the need for 3.3V
power supply, lowering system cost and simplifying design
• 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.
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 and
• simplified
power supply.
