• Single and two-step IEEE 1588v2 time

• Wireless backhaul systems

• Carrier Ethernet cellular base stations

• Industrial automation systems

Microsemi’s new GbE PHY simplifi es Synchronous Ethernet and

IEEE1588 timing in Carrier Ethernet designs.

VSC8574 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. VSC8574 supports four dual media

copper/fi ber ports with SGMII and QSGMII MAC interfaces. Recovered

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, VSC8574 supports various encapsulation links

including IP over MPLS, Ethernet pseudowire over MPLS/MPLS-TP,

QinQ, and MAC-in-MAC.

VSC8574 supports ring resiliency, a feature that enables PHY ports

to switch between master and slave timing without interrupting the

1000BASE-T link. VSC8574 has integrated temperature monitoring and

operating speeds.
