Part Number: DAC3482EVM
After some difficulty in getting the registers to load (see previous postings), I finally got everything (DAC3482, CDCE62005 and TSW1400) configured as described in the DAC3482EVM manual (Section 3.4 - DAC348x Example Setup Procedure). This produced an output that looks somewhat related to the correct waveform. However, it seems like something saturating or the data capture is introducing some errors. I tried a number of different registers adjustments to see if I could resolve the problem. Most of my register changed altered the output spectrum (so I am changing things!), but none were correct. The spectrum I'm getting when I use the precise register values specified in the EVM manual is the following:
Of course, from the EVM manual, what I'm expecting to see is:
Any suggestions appreciated.
