Low-power PHY supports IEEE 802.3az Energy Effi cient Ethernet.
The VSC8502 device is designed for space-constrained
10/100/1000BASE-T applications. It features integrated line-side
termination to conserve board space, to lower EMI, and to improve
system performance. To further reduce system complexity, component
count, and system cost, the VSC8502 device can operate from a
single 3.3 V supply using integrated voltage regulators that provide the
necessary 1.0 V and 2.5 V rails for operation. Additionally, integrated
RGMII timing compensation eliminates the need for on-board delay
lines.
The VSC8502 device includes Microsemi’s EcoEthernet™ 2.0
technology that supports Energy Effi cient Ethernet and power saving
features to reduce power based on link state and cable reach. The
device optimizes power consumption in all link operating speeds and
features Wake-on-LAN (WOL) power management using magic packets.
The VSC8502 device also includes fast link failure indication for high-
availability networks. Fast link failure indication identifi es the onset of
a link failure in less than 1 ms typical to go beyond the IEEE 802.3
standard requirement of 750 ms ±10 ms (link master).
Synchronous Ethernet and Ring Resiliency™ are supported. The device
has two recovered clock outputs for Synchronous Ethernet applications.
Programmable clock squelch control is included to inhibit undesirable
clocks from propagating and to help prevent timing loops. Ring
Resiliency allows a PHY port to switch between master and slave timing
references with no link drop in 1000BASE-T mode.
