I am using an 18.432MHz TCXO with +/-0.28ppm Frequency Stability vs Temperature. I am feeding this as REFCLK to the AD9913. With PLL Multiplication set to x13, i get a SYSCLK of 239.616MHz. I am generating an output of 32MHz Sinewave. What will be the Frequency Stability of the whole unit vs Temperature...? Will it remain +/-0.28ppm...? or Will it also increase....?
Advance Thanks and Regards,
