【应用】爱普生SAW谐振器替代AT+PLL振荡器,实现低抖动和相位噪声的高频输出
虽然AT切割晶振与倍频器或PPL电路相结合可以实现高频输出,但是其晶体振动电路设计复杂,且难以防止抖动和相位噪声。为了获得出色的抖动和相位噪声特性,实现高频晶振需要很薄的晶振片。由于处理的方法和机械强度等问题,晶振片的厚度是受到限制的。爱普生SAW(声表面波)谐振器XG-2102CA能够解决上述问题,并且直接实现高频基波振荡。
1、爱普生SAW谐振器:
类似于波浪穿过水体表面的方式,声表面波是通过在弹性体表面聚集能量而传播的波。波的振幅在深度方向上呈指数衰减。如图1所示,声表面波可以通过安装在压电基片上的IDT(Inter Digital Transducer)产生和检测。频率(f)可以使用公式f = V /λ导出,其中表面波传播速度为V,IDT周期为λ。如图2所示,SAW谐振器可以被分为两种类型:单端口谐振器和双端口谐振器。
图1 原理示意图
2、爱普生SAW谐振器的特性:
SAW谐振器振动模型是基于声表面波(见图3的右图),其频率取决于晶振片IDT的宽度而不是厚度。基频和三次谐波的频率兼容范围分别为10MHz~50MHz、50MHz~150MHz。其他的特性包括:相对于AT晶振的厚度剪切模式,噪声对主振荡器的影响很小;对于贴附在电极薄膜的异物,具有出色的稳定性。当谐振器安装在一个振荡器上,这些特性提供了低抖动。并且这些特性能够消除一些危害,比如振荡停止。
对比SAW产品与AT产品,爱普生SAW谐振器产品XG-2102CA改善了正交曲线的浮动范围,同时也提高了精度。

3、爱普生SAW振荡器XG-2102CA的优势:
图4 相位抖动和功率消耗的对比
图5 SAW振荡器和AT + PLL振荡器的相位噪声特性比较
PLL使用一个高Q值的晶体振荡器来驱动压控振荡器(VCO)并输出倍频。因此,相位噪声特性由两个元件决定:振荡器电路和VCO。一般来说,VCO相位噪声特性比晶振差,而在PLL的情况下,VCO的相位噪声特性将出现在高通侧,这将导致一部分相位噪声曲线上升。
PLL振荡器是由一个基于“晶振电路+PLL”组成的,通常这意味着PLL电路的外设需要一个更高水平的功耗。相反地,SAW振荡器的振动模型能够在一个很高的基频上振荡。这就使得电路结构简单,以至于能够减小功耗。

娇小体积的贴片晶振要注意什么?
近年来,随着智能手机,计算机和电视等电子产品的轻量化以及导航天线和芯片(模块)等核心组件的技术进步,小尺寸低功耗的核心组件逐渐被推广到市场,内部组件随着尺寸的增加而逐渐减小。本文将介绍在小体积的晶体振荡器中我们应该注意什么。
技术探讨 发布时间 : 2023-12-14
【经验】采用SAW振荡器获得高频输出的方法,实现低抖动特性并避免振荡停止等风险
本文将对爱普生SAW振荡器进行解说。这种振荡器使用了能够解决起振石英晶体单元的振荡电路设计较为复杂,以及难以抑制抖动和相位噪音的课题。将通过与AT型石英晶体和锁相环电路相组合的SAW振荡器(爱普生XG-2102CA)相比较,以此证明SAW振荡器的特性。
