CMAC(C-MAC MicroTechnology )公司简介
from Indro Mukerjee, CEO 
 
We are a global business employing over 750 people in Europe and North America. Our people are our biggest asset and we’re pleased to have many of the very best in the industry. 
 
We offer our customers specialist skills in semiconductor and system design, product development and high-quality electronics manufacturing, as well as test and quality assurance. 
 
 
 
Our products are typically found in: 
 
High-frequency systems 
High-current systems 
Safety critical applications 
Systems required to function reliably under conditions of extreme temperature, humidity, vibration and/or shock 
Applications requiring supplier accreditations such as ISO TS 16949, ISO 13485 and QC001002-3. 
We’re proud to be called a trusted partner by many of the world’s leading companies, and frequently open our facilities up for customer inspection and audit. Our company culture is all about performing to high quality standards and delivering to promise. Whatever we’ve achieved in the past, we always aim higher next time. 
 
We offer customers a complete high-precision microelectronics manufacturing capability ranging from prototype design and simulation through to manufacture and test of finished product. 
 
We are able to provide solutions to the most demanding customer requirements through a broad range of technologies, and skills including: expert know-how relating to the design for manufacture of very high frequency electronics, expertise in thermal management in complex electronic designs and leading technology for advanced electronic interconnection. This expertise enables C-MAC to offer a range of solutions in such application areas as RF & Microwave modules, high power LED arrays, complex system in package and multichip semiconductor packaging. At its locations C-MAC has invested in a wide technology footprint, which includes: Chip & Wire, Flip Chip, Chip Testing, Thick Film Hybrid assembly and LTCC (Low Temperature Co-Fired Ceramics). These technologies are particularly relevant in high reliability applications, for example in the Automotive industry where there is an increased distribution of electronics sensors throughout vehicles. This results in electronics having to operate at high temperature and extremes of vibration. C-MAC has been involved for a number of years designing and manufacturing electronic systems, packaging MEMS sensors and other semiconductors for these kind of demanding applications, where long term reliability is a prerequisite.

◇ CMAC(C-MAC MicroTechnology )新品推荐

C-MAC MicroTechnology公司推出了第一款基于其专利性稳步补偿炉温受控晶体振荡器(TC-OCXO)技术的商业产品。这些新款CFPO-20系列产品具备OCXO的高稳定性和TCXO的相对低功耗、小尺寸及重量轻的特点，在整个工作温度范围内，5MHz到20MHz的输出频率下的稳定度达到±0.025ppm。

CFPO-20系列产品主要是为GPS、卫星通信和安全射频等移动、电池供电及遥控设备设计的。这些设备通常需要同时使用尺寸小、功率低，但不能用作稳定的标准频率源的TCXO器件和稳定性至少高一个量级，但封装尺寸、功耗和成本更大的OCXO器件。

CFPO-20系列器件采用标准20.7×13.08mm DIL封装，通过利用单个微型烤箱使晶体振荡器保持在其额定工作温度范围之上的近似恒定温度，利用C-MAC的Pluto温度补偿技术对残余相关温度频率误差进行补偿将TCXO和OCXO的优势集于一身。

在3.3V或5V的电源电压下，CFPO-20系列器件在-20℃到70℃工作温度范围内的稳定度达到±0.025ppm，或-40℃到80℃工作温度范围内的稳定度达到±0.05ppm，而在上述温度范围内，-20℃定态下的功耗则分别小于400mW和525mW。

CFPO-20系列器件的标准输出频率为5、6.4、8和8.192MHz，可提供方形HCMOS输出，也可提供10、12.8、16、16.384和20MHz的方形HCMOS或AC耦合剪切正弦波输出。此外，还可输出符合特定规范的1.25到33MHz的方形ACMOS和DC耦合正弦波输出。在输出频率最高20MHz条件下，这些器件的10年老化率为±3ppm，而在20MHz以上频率输出时，为±5ppm，而频率的可调节度分别为±5ppm或±7ppm，可实现对器件老化的补偿。

根据批量和产品规格的不同，这种新型CFPO-20 TC-OCXO器件的单价在24到60美元之间(仅供参考)。
