INTERFACING OF DAC34H84 WITH TSW1400
In the above fig, I am interfacing DAC34H84 evaluation board with TSW1400.
CLK SOURCE: 1.228GHz (fdac) at 1.5Vrms
Power Supply: DAC Board: 6V, TSW1400: 5V 3A
In the above fig., without applying the interpolation factor and disabling the PLL and NCO, I am setting the tone frequency to 20MHz.
but now as encircled in the above fig of CRO, I am not getting 20MHz sine wave as given at the input side.
PLEASE LET ME KNOW WHAT CHANGES ARE REQUIRED.
I AM ALSO ATTACHING THE INTERFACING DIAGRAM BELOW:
