K Series Clock Oscillators KYOCERA AVX K Series Surface-Mount Clock Oscillators feature CMOS output and 1.5MHz to 80MHz frequency range. The series has a 1.6V to 3.63V wide supply voltage and CMOS output. KYOCERA AVX oscillators utilize a simplified structure with a common sized head unit and changing base substrate to support case sizes from 2016 to 7050, allowing for reduced cycle times. An optional low phase noise version is available.
