Quad Channel 1G/10GBASE-KR to SFI Ethernet WIS PHY with VeriTime™

Product Detail

VSC8257 is a quad 1G/10G serial-to-serial Ethernet PHY featuring VeriTime™, Microsemi’s IEEE 1588v2 network timing technology. It also supports dual-sided 10GBASE-KR functionality including auto-negotiation and training in a small form factor, low-power FCBGA ideal for a wide array of board-level signal integrity designs and system-level IEEE standard compliant Ethernet connectivity.VeriTime™ is Microsemi’s patent-pending network timing technology that delivers the industry’s most accurate IEEE 1588v2 implementation. It is the only IEEE 1588v2 solution to be validated by major OEMs in real-world tests, and it has already been adopted as the preferred low-cost upgrade for meeting emerging requirements in 4G/LTE-Advanced (LTE-A). The VSC8257 device supports both 1-step and 2-step PTP frames for ordinary clock, boundary clock, and transparent clock modes of operation, along with complete Y.1731 OAM performance monitoring capabilities.
