dac interface with pic16f877a
which would be more advisable, to use a higher or a lower frequency for our reference clock in AD9850??? I am aware that lower frequencies would give me a tighter frequency resolution, but, do the reference frequency affect the DAC? i have this weird feeling that using higher ref freq would give me a finer DAC output. i stand to be corrected.. heheh..
we only have this frequencies to choose from: 80MHz, 64MHz, 50MHz or 24MHz. we are only interested in having a maximum output frequency of 1MHz.
