Other Parts Discussed in Thread: ADS54J60
Hi,
I'm using a TSW54J60EVM and a TSW14J56EVM to evaluate the ADS54J60 and the LMH6401. I have captured raw data from a sine wave (10MHz, 0dBm) and also from a DC signal (50ohm to ground). The time domain and frequency domain graphs seem correct however the histograms are problematic.
The histogram of an ideal sine wave should be displayed as a nice "single-line" bathtub curve. However, the raw data captures with "High Speed Converter Pro" shows non-linearities. See figure below.
The histogram of an ideal DC signal should be displayed as a nice "single-line" narrow bell curve. However, the raw data captures with "High Speed Converter Pro" shows non-linearities. See figure below.
Do you have measurements for Integral non linearity error (INL error) or Differential non linearity error (DNL) for the ADS54J60?
Thanks,
Patrice
