I am designing a DAC stage that will be used together with a DSP. The system master clock is generated in the digital domain, hence it is referenced to digital ground. My DAC is completely referenced to the analog ground. I need to implement a clean way of transferring the master clock from the digital domain to the analog domain, in order to avoid excess clock jitter caused by voltage differences between digital and analog ground.
Could you please suggest a suitable component for this a task, such as a differential line driver, some kind of transformer, or an optical device? Which method is best?
I only need one input and one output. The master clock frequency is 24.576 MHz
