Generally, the jitter parameters are expressed in FS, but when the jitter value is less than 1ps, it is expressed in femtosecond (FS). At present, only a few specially optimized crystals can achieve the jitter performance of femtosecond level 1ppm refers to the long-term stability of crystal oscillator, which is used to measure the long-term frequency error of clock. It is usually expressed in ppm, which is one millionth. These are two different concepts. For digital audio, the first is jitter performance, and the second is long-term stability This module is used to directly replace and upgrade the rectangular 4-pin active crystal oscillator of 11.2896mhz. Working voltage: DC 5V Output frequency: 11.2896mhz Output level: HCMOS 5vpp Output waveform: square wave Size: 19 x 14.2 mm, equivalent to ordinary rectangular active crystal oscillator The module design is used for cdm3, cdm4 and other rocker head CD players and CD turntables. The clock frequency of the rocker head machine is basically 11.2896mhz. Because the crystal oscillator of crystek cchd-957-25 series does not have the frequency of 11.2896mhz, so it can not be used directly. Therefore, the module is designed. The ultra-low phase noise crystal oscillator of 22.5792mhz in crystek cchd-957-25 series is used. After processing, it is transmitted The frequency of 11.2896mhz of 5vpp square wave level can directly replace or upgrade the crystal oscillator of the rocker optical head turntable.
