VSC8257数据手册集成电路（IC）的电信规格书PDF

描述 Description

VSC8257 is a quad 1G/10G serial-to-serial Ethernet PHY featuring VeriTime™, Microchip’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 Microchip’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.Target applications for the VSC8257 device include switching, IP edge router connectivity, rack mount server access through backplane, fiber and copper cable connectivity, and standalone server access (in LAN on motherboard designs or separate network adapters).The device delivers excellent jitter attenuation with low power. It is also well-suited for SFP+ and QSFP+ based optical modules and direct attach copper cabling as well as challenging backplane interface applications.Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design. MicroCHECK design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
