Clock tree with LTC6951 as reference and LTC6952 as clock distribution in parallel sync?

Wondering if it is possible to use the LTC6951 internal oscillator as reference to the LTC6952? The LTC6952 function as clock distribution for multiple JESD ADC and DAC.  I do not want to use an external clock for this clock tree architecture. Nor do I want to use multiple LTC6951, the configuration waste a lot of I/O. 

  • I think to answer this question fully I will need to understand your reference frequency, how many clocks and SYSREFs you need, and your clock frequencies.  From your description, I'm not exactly sure what you is being asked.

     Usually you want a ultra low noise OCXO or XO reference as an input to the LTC6952 to obtain best performance.  You can send a ultra low noise reference into a LTC6954, LTC6953 and distribute that to several LTC6952s in parallelSync.
