Thread Summary

                The user asked if the LTM4651 can support a spread-spectrum input clock from the LTC6909. The LTM4651 can accept a spread-spectrum clock as long as the CLKIN frequency is within ±40% of the oscillator frequency set by the fset pin. No specific parameters beyond this tolerance were mentioned.

Can the LTM4651 support an input CLKIN signal that incorporates spread-spectrum frequency shifting?


More specifically, can it support the spread-spectrum input clock from the LTC6909?


If the the LTM4651 can accept a spread-spectrum clock input from the LTC6909, are there any specific required parameters?


Thanks in advance,


Chris
