Hi,

 

With AD9915 Ev.Board i observe that:

- DRG Freq. Jump function works. (For ex: 10-11-12-13-14-15 MHz then jump to 75MHz, then 76-77-78-79-80MHz.)

- DRG Freq. function also works WHEN no-Dwell high&low bits are both set / WITHOUT Freq. Jump.

  (For ex. 10-11-12-..-79-80MHz.)

 

But, when programming AD9915 for the below scenario DDS's jump function doesn't work.

   * No-Dwell high&low bits are both set,

   * Freq. levels are: 10-11-12-13-14-15 MHz then jump to 75MHz, then 76-77-78-79-80MHz.

 

As i see, datasheets don't mention a limitation like this.

Is DRG Freq. Jump function works WHEN no-Dwell high&low bits are both set?
