Dual Port Dual Media RGMII/SGMII GbE PHY with IEEE 1588
Microsemi’s new GbE PHY simplifies Synchronous Ethernet and
IEEE 1588 timing in Carrier Ethernet designs.
VSC8572 is the next-generation Carrier Ethernet Gigabit PHY
transceiver designed to simplify the support of fully traceable timing
across Gigabit Ethernet backhaul devices, cellular base stations, and
other timing-critical platforms. VSC8572 supports two dual media
copper/fiber ports with RGMII and SGMII MAC interfaces. Recovered
clock outputs and an integrated IEEE 1588 timing packet engine enable
the VSC8572 device to meet the demands of applications requiring
highly precise timing, without adding unnecessary complexity or
increased cost to the design.
To meet Carrier demands for redundancy, the VSC8572 device has dual
recovered clock outputs for primary and secondary timing references for
Synchronous Ethernet solutions. Programmable clock squelch control
is included for inhibiting undesirable clocks from propagating and
preventing timing loops.
In addition to identifying PTP Y.1731 in Ethernet and IPv4/6 over
Ethernet per IEEE 1588, VSC8572 supports various encapsulation links
including IP over MPLS, Ethernet pseudowire over MPLS/MPLSTP,
QinQ, and MAC-in-MAC. VSC8572 supports ring resiliency, a feature
that enables PHY ports to switch between master and slave timing
without interrupting the 1000BASE-T link. VSC8572 has integrated
temperature monitoring and is ideal for high-temperature applications.
Microsemi’s innovative EcoEthernet 2.0 technology supports Energy
Efficient Ethernet (EEE) through ActiPHY™ automatic link powerdown
and the PerfectReach™ intelligent algorithm that adjusts power based
on cable length. VSC8572 further supports reduced power consumption
in all link operating speeds.
