I program the frequency of my device using a tuning word of 32 bits,
00000100 00011000 10010011 01110101 and I get an output frequency of 2 Mhz. I am unable to how this sequence of digits works.
From the datasheet
The relationship of the output frequency, reference clock, and tuning word of the AD9850 is determined by the formula
fOUT = (Phase × CLKIN)/2^32
Phase is the value of the 32-bit tuning word.
CLKIN is the input reference clock frequency in MHz.
fOUT is the frequency of the output signal in MHz.
Maybe this is producing hex words rather than a number ?
Could someone perform a specimen calculation for say 500 Khz and then for 1500 Khz so I can see how it works and how the string of digits is obtained ?
Also I would be grateful if someone may be able to point out the meaning of the power-down bit.
