Device Overview

Summary

VSC8254 is a dual 1G/10G serial-to-serial Ethernet PHY featuring VeriTime™ (IEEE 1588v2) and Intellisec™ (128/256-bit MACsec) encryption. 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 (intelligent) Ethernet connectivity. VeriTime™ is Microchip's patent-pending timing technology that delivers the industry’s most accurate IEEE 1588v2 timing implementation. It is the only IEEE 1588v2 solution to be validated by major OEMs in real-world tests and adopted as the preferred low-cost upgrade for meeting emerging requirements in 4G/LTE-Advanced (LTE-A).

Microchip's patent-pending flow-based extension of the IEEE 802.1AE-based, end-to-end MACsec solution for confidential communications over any MEF CE 2.0 Ethernet or MPLS service provider connections. It is the world’s first FIPS 197-certified CGM-AES 256-bit strong MACsec, with legacy support for today's CGM-AES 128-bit field deployments. The VSC8254 device supports full line rate encryption at both 1GbE and 10GbE speeds over multiple media types. Target applications for the VSC8254 device include Ethernet switching, IP edge router connectivity, rack mount connectivity through backplane, fiber and copper cable connectivity, and standalone server access (LAN on motherboard designs or separate network adapters).

The VSC8254 device delivers excellent jitter attenuation with low power. It is well-suited for SFP+ modules and direct attach copper cabling as well as challenging backplane interface applications.
