What I am trying to accomplish requires low power, small package size and ultra low starting phase jitter. Can someone recommend the best DDS for this purpose?
How much jitter do you need and at what frequency?
I need it for 6 frequencies: 144KHz 152KHz 392KHz, 400KHz, 1.992MHz and 2MHz. Right now I'm using the AD5932YRUZ. From what I can tell on the scope, it is showing about 20ns of jitter in reference to our Sync Edge.
I don't have the full tabulated data of the jitter performance on all of the DDS products that we have right now. But the jitter performance of the DDS is heavily affected by the jitter of the clock. So I suggest a very low jitter clock source on the DDS, lower than the jitter you want to specify.
