Forum Post: RE: DAC3482 Harmonics at the output
Hi Prasad,Could you let me know how do you generate the LTE waveform? Did you generate this waveform from our HSDC PRO/TSW1400 LTE GUI? If so, the output waveform in .tsw format is encoded and may...

Basically, if the lower 10 bits are always saturated then the ADC is unable to resolve an input level that is less than 2^10/2^16 of its full-scale input range. In other words, the ADC is behaving like...

The purple trace is RESET.For now, we seem to have things running well with higher valued damping / series termination resistors on the lines to the EVM board, thus suppressing those noise spikes a bit...

After comparing my code with yours (Im using the DM6467) in your function TVP5158_setOfmMode() your B7 should be set to 0x04 not 0x14. Check if that helps.
