自从cc1被两仪总狙击了以后就没声音了?
grimm cc1/2最初是为avid接口开发的。
cc1是一款wck时钟,把一款不算发烧的晶振利用技术做出牛逼的wck频率。作为工业品的10m时钟参数做得极致其实不难,但合成是个问题。
现在一股追求10m时钟指标风是不是该反思了?
翻遍grimm cc1产品白皮书,它是极力反对工业品10m合成音频频率。按它的说法:
The greatest common denominator between 44.1kHz and 10MHz for instance is 100Hz. It is exceedingly difficult to make a synthesizer with such a ratio that doesn’t have significant jitter products at 100Hz intervals. If the aim of the undertaking is to minimize jitter, bringing in a 10MHz laboratory standard is a surefire way of making things much more complicated and much more expensive.
The lowest jitter clock you can ever get is a really good crystal oscillator that puts out the frequency you want (or an integer multiple) directly. This is what the CC1 does
