DAC38RF82EVM: DAC38RF8X EVM GUI has a limits on DAC's sample clcok?
Part Number: DAC38RF82
Is there a relevant glitch impulse spec for the DAC38RF8x devices?
Asking on behalf of a customer.
We do not have any data recorded on the glitch impulse for this family of devices. Depending on the the particular condition that the customer wants to measure we could possibly capture it if needed.
Is there a specific condition that the customer is wanting measured?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to David Chaparro:
They are interested in the voltage glitch when you roll over the MSB (right at mid-scale). The transition from 0x7FFF to 0x8000 when running with a 2.4GHz clock.
I believe this is operating mode 2TX LMFSHd = 82121.
In reply to Antenna_Head:
I am working on getting data that you will be able to share with the customer.
I was able to test and measure the voltage glitch of the DAC38RF82. Using the TSW14J56 and HSDC Pro, a test pattern file that repeatedly converted from 0x7FFF to 0x8000 was used as the input to the DAC along with a 2.4GHz clock as you had mentioned. The attached pictures are the results that were captured on the o-scope. As seen in the pictures the voltage glitch has a voltage drop of about 500mV and then a voltage increase of about 200mV (compared to the voltage before the glitch), the signal than continues to fluctuate for about 200ms. This is everything I have on the voltage glitch of the DAC38RF82.
Hope that provides sufficient data.
