VSC8575
Quad-Port 10/100/1000BASE-T PHY with Synchronous Ethernet, VeriTime™, and QSGMII/SGMII MAC
The quad port VSC8575 GbE PHY with VeriTime™ is ideal for
securing cloud network applications including e-commerce, database,
collaboration, smart grid, video, and enterprise or government
communications.
VeriTime™ is Microsemi’s patent-pending timing technology that delivers
the industry's most accurate IEEE 1588v2 timing implementation
available on the market today (±4 ns accuracy, 1 ns precision,
1000BASE-T).
VSC8575 supports Y.1731 OAM and MPLS-TP OAM for accurate delay
measurement and performance monitoring. In addition, it includes dual
recovered clock outputs for timing references in Synchronous Ethernet
solutions. Using Microsemi's Ring Resiliency™ technology, the PHY
switches between master and slave timing without interrupting the
1000BASE-T link.
The device includes a simplified hardware and software migration path
for designs already using VSC8574, VSC8572, VSC8504, or VSC8552
devices. It serves as the perfect alternative to the VSC8584 or VSC8582
devices for designs that need the highest 1588v2 PTP accuracy, but
may not need MACsec 256-bit/128-bit encryption.
