美国QVS晶振推出MEMS变频产品替代石英振荡器

QVS Tech Inc.宣布现在向全球提供微机电传感器(MEMS)频率控制产品。他们使用基于硅的MEMS振荡器CMOS电路，而不是基于石英的谐振器来产生频率，这是大多数石英晶体振荡器的替代品。一个关键的优势是它在2.0 mm x 1.6 mm,，2.5 mm x 2.0 mm，3.2×2.5 mm和5.0 mm x 3.2 mm的尺寸上提供了紧密的频率稳定性。新产品系列被称为QMEM系列，其LVCMOS系列与时钟振荡器器件兼容。

这些MEMS频率控制产品的通常应用是光纤通道，千兆以太网，服务器，路由器，PCI Express，网络交换，FBDIMM, SATA/SAS, ATM, SONET和SDH。它们还可用于扫描仪、医疗设备、调制解调器、打印机、照相机、笔记本电脑和PDAs。

这些MEMS频率控制产品提供各种技术优势。它们是完全可配置的，具有1 MHz至110 MHz的宽频率范围。有+1.8V、+2.5V、+2.8V、+3.3V等多种电源电压可供选择。它们在广泛的工作温度范围内提供+/- 20ppm的频率稳定性。它们具有低毫秒周期抖动，并且具有50% +/- 5%的紧凑占空比选项。它们不含卤素，不含铅，不含锑。它们也符合有害物质限制指令(RoHS)和欧盟委员会的REACH法规。QVS科技提供5天甚至更短时间内的快速送货服务。

正如名字所示，QVS Tech Inc的核心原则“质量、价值和服务”将不断引领公司走向更高的卓越水平。通过将一流的制造设施、晶体和振荡器领域的专业管理知识、非常广泛的产品线以及高级别的服务和支持相结合，QVS Tech Inc正在发展成为频率控制行业的领导者。

QVS Tech Inc. has announced that they are now offering microelectromechanical sensor (MEMS) frequency control products. They use a silicon-based MEMS oscillator CMOS circuit as opposed to a quartz based resonator for frequency generation. This is a drop in replacement for most quartz based oscillators. A key advantage is that it provides tight frequency stability in sizes of 2.0 mm x 1.6 mm, 2.5 mm x 2.0 mm, 3.2×2.5 mm and 5.0 mm x 3.2 mm. The new product series is known as the QMEM series and their LVCMOS series is compatible with clock oscillator devices.

The usual applications for these MEMS frequency control products are Fiber Channel, Gigabit Ethernet, Servers, Routers, PCI Express, network switching, FBDIMM, SATA/SAS, ATM, SONET, and SDH. They can also be used in scanners, medical equipment, modems, printers, cameras, notebook computers, and PDAs.

These MEMS frequency control products offer various technical benefits. They are fully configurable and have a wide frequency range of 1 MHz to 110 MHz. Several supply voltages are available, such as +1.8V, +2.5V, +2.8V, and +3.3V. They offer +/- 20ppm frequency stability in a wide range of operating temperatures. They have low ms period jitter and they have tight duty cycle options of 50 percent +/- 5 percent. They are halogen free, lead free, and antimony free. They are also compliant with the Restriction of Hazardous Substances Directive (RoHS) and the REACH regulation of the European Commission. QVS Tech offers fast delivery in five days or even less.

As our name suggests, our core principals of “Quality, Value, and Service” will continually lead us to higher levels of excellence. By combining top-notch manufacturing facilities, management expertise specializing in the crystal and oscillator arena, a very broad product line offering and superior levels of service and support, QVS TECH is developing into a leader in the frequency control industry.
