【应用】Epson超低抖动晶体振荡器为Altera®的FPGA提供时钟解决方案
EPSON(爱普生)公司成立于1942年5月,总部位于日本, EPSON晶体产品,占全球市场份额超过1/5,是全球最大的晶体时钟产品提供商,且是全球最大的晶率覆盖范围厂商,实现从KHz至GHz全覆盖。近年,随着各种网络通信的大容量化及高速化,顾客在构建各种系统时,越来越需要性能更加可靠的参考时钟。因此网络设备对高标准参考时钟的需求尤其突出,要求作为系统性能重要参数的相位抖动具备低抖动特征。
Epson公司推出的XG-2102CA,SG7050EBN是两款具有超低抖动和超低相位噪声的晶体振荡器。XG-2102CA输出频率范围为100MHz~700MHz,相位抖动低至0.1ps Max.(@600MHz≤f0≤700MHz,偏移频率12kHz~20MHz),可有效降低通信系统的误码率。SG7050EBN输出形式为LV-PECL,输出频率范围为100MHz至175MHz,相位抖动能够实现65fs Typ.(起振频率156.25MHz,VCC=3.3 V ±0.165 V),实现了高标准规格,能够满足高端路由器等有线网络设备及高速串行通信的参考时钟要求。
Epson公司与许多IC制造商合作,为其提供时钟解决方案。本文即介绍EPSON晶振产品XG-2102CA,SG7050EBN为Altera®公司的FPGA产品(Stratix®V,Arria®V,Cyclone®V作为PCI Express®收发器时)提供时钟解决方案。
PCI Express® (PCIe®)是一种高速串行传输标准,广泛应用于PC、服务器、设备、测量设备、广播产品等。FPGA可作为这些应用的PCIe®收发器。Epson的振荡器产品XG-2102CA,SG7050EBN在以下实际评估过程中被验证作为参考时钟有优秀的性能。
图1:PCIe 传输基本框图
参考时钟可用性的确认方法
1. 将Epson振荡器产品与 Altera Arria®V PCIe® 板连接。
图2:测量过程说明图
图3:测量场景
1. 用示波器测量PCIe® TX输出。
2. 用示波器的眼图和RMS数据计算BER。
测量过程中对比了包括Epson的振荡器产品XG-2102CA,SG7050EBN在内的三款振荡器的BER结果,XG-2102CA,SG7050EBN均展示了优于另一款的优秀性能,而SG7050EBN实现的最佳的BER性能。

【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)谐振器的振荡器XG-2102CA能够解决上述问题,并且直接实现高频基波振荡。
