VITA标准组织

VITA标准组织

VITA成员共同致力于定义和开发关键计算机总线、电路板和体系规范,如VME总线,PCI夹层卡(PMC),VXS,VPX和FMC等等。VITA于1984年成立以来,形成了近100个工作团队,开发了对于全世界关键嵌入式系统设计师来说尤为重要的各项规范和标准。体系覆盖从医学成像到太空发射控制,从半导体加工到国防系统,无一不依托基于VITA技术打造的产品。

VITA在标准的专利发布和授权上谱写了新篇章,成为了 世界上第一个接受权威法定机构“事前”程序指导的标准制定者。VITA经常被美国司法部引述为“事前”程序的行为榜样。访问专利发布 页面查看更多信息。

世界的安全、控制、防卫、通信、娱乐、交通和许多其他应用均需依托VITA技术。

VITA 42 XMC

XMC标识

VITA 42 XMC是广泛部署的夹层标准,适用于高可靠性计算机实现的交换式架构。XMC结合了PCI夹层卡(PMC)与基于经验证的夹层形状因子的串行结构技术。

VITA 57.1 FMC

FMC标识

FPGA夹层卡(FMC)由FPGA供应商和VITA 57个工作团队的终端用户成员联合开发签署。FMC是一项ANSI标准,定义了子卡的紧凑型机电扩展接口,可连接到FPGA基板或其他设备上,采用可重新配置的I/O口。

FMC标准对于FPGA供应商制造基板及综合开发工具包来说至关重要,支持设计师加速应用开发过程。供应厂商也不断在各行业目标市场的特定应用中推广FMC产品,例如数据通信、广播、航空航天/国防、工业和仪器仪表等领域。点击这里查看更多关于FMC I/O口设计灵活性的相关信息。

VITA 57.4 FMC+

FMC+标识

基于原有FMC,FMC+采用了更为大型的SEARAY™家族高速高密度阵列连接器。该高串行端子连接器(HSPC)拥有560个端子,以14x40阵列分布。新型FMC+卡由于采用了较大型连接器,只能插入到新型FMC+载体中,原有FMC卡因定制的顶针系统也可同样适用于新型载体,提供真正意义上的向后兼容。

FMC+标准将数千兆位接口的数量从10个提升到24个。此外,提供可选扩展连接器(高串行端子连接器扩展,即HSPCe),增加80个针位,以4x20阵列分布。进一步将最大数千兆位接口增加到32个全双工通道,每个数千兆位接口的双向输出可增加到28 Gbps。

VITA 74 VNX

VNX标识

VITA 74 NanoX小型化既定义了机械规范也定义了电气规范,便于实现小型系统。该规范阐述了适用于各种应用的小规模系统对于标准化方法的需求,鼓励各供应商提供各层级小型系统所使用的组件,包括模块、背板、封装以及完整解决方案。目的在于支持供应商实现灵活性,同时确保组件的可互操作性。

In this new video, Samtec’s Kevin Burt introduces Samtec Direct Connect™. Direct Connect gives the benefit of exiting a higher number of lanes at low loss from the chip package, which can be very useful in both high performance computing and network switching applications, especi...
This is the first release of a few phases of a new login system for Samtec.com. This replaces a system that was built in 2011 and has been running well ever since. But, technology changes over time, and it was time for an upgrade. Here are some additional details about the featur...
Modern electronic devices are getting smaller with every new generation, and as a result, they are becoming more portable.  At the same time, the performance of these devices is growing as the demands of consumers become greater.  We expect to be able to connect to the internet w...
This month, we released a major upgrade to our login experience across Samtec.com, as well as an overview of our 5G technology capabilities, and an easier way to get real-time availability for products across Samtec.com. Here are the major updates to Samtec.com for July 2019. Rea...
They say, “a diamond is forever,” but did they really test that or is it just a marketing statement? No need to search for that answer because we all know they didn’t. However, in our industry it is important to know what to expect out of a connector, and that is why Extended Lif...
