A programmable oscillator is simply an oscillator in which the resonator frequency is post-processed to the desired output frequency utilizing an integer-mode or fractional-phase-locked loop (PLL). The resonator employed is either a bulk acoustic wave (BAW) quartz crystal resonator or a MEMS (Micro-Electro-Mechanical System) resonator. The oscillator output frequency and other operational functions are configured using the internal programmable memory of the integrated circuit. This circuit is comprised of an oscillator loop, a typical phase-locked loop (PLL) and associated functional blocks to facilitate various bias level and output logic configurations.
Utilizing a proprietary resonator design and exclusive programming methods, Ecliptek and associated Abracon brands of programmable oscillator series are configured to the specified frequency and functional configuration prior to shipment to the customer. Key features of this capability include fast delivery, greater availability of unique frequencies, various supply voltages and output logics, and industry-standard package sizes.
Ecliptek’s programming capability offers a quick-turn delivery of low, medium and high-volume programmable oscillators, resulting in the shortening of the customer design cycle and the delivery of production lots. These solutions are ideally suited for industrial, consumer, data centers and telecommunications infrastructure architectures.
由于频率测定可以达到很高的精度,估计检测限可达10-12g,因此利用这一特性,振动的石英晶振晶体可以制成非常灵敏的质量检测器一石英晶体微天平( quartz crystal microbalance,QCM)。
对于指定石英晶振晶片,fo、A、pμ、Hμ均为常数,因而,△f与△m的绝对值成正比,负号表示表面银电极层质量的增加,会引起石英晶体谐振频率的减少;而表面银电极层质量的减少,会引起石英晶体谐振频率的增加。即:增加银层质量和减少银层质量两种方法都可以改变石英晶振的谐振频率。
