AK2、AX3、AK5和AK7解决方案具有出色的RMS抖动性能,远低于200fs的典型系统级最大要求。对于要求保证最大RMS抖动性能为100fS的系统,AK5和AK7解决方案在工作电压为3.3v时,不管是采用LVDS还是LVPECL输出格式,均可满足这一要求。ASGTX5温补晶振(TCXO)系列除了提供标准频率(厂家无法配置)的ClearClockTM解决方案,Abracon还开发了ASGTX5系列。此系列可以满足Stratum-IV时钟系统的总稳定度要求:最大32ppm。该要求包括初始设置公差、晶振经过回流焊后的频率偏移、供电电压和负载变化导致的频率偏差,在工作温度范围-40℃到+85℃的频率偏差,以及老化(20年)偏差等。ASGTX5温补晶振(TCXO)解决方案可在15.0MHz至2.1GHz之间的任何载频下满足上述严格要求。然而,为了达到这一精度,该解决方案的RMS抖动稍差于相对应的三次泛音ClearClockTM方案。例如,该方案在156.25MHz载波上表现出小于350fs的典型RMS抖动。除了标准LVDS、LVPECL和HCSL之外,ASGTX5还提供CML差分输出格式。需要CML输出类型的系统应用必将从ASGTX5系列中受益。
