Tool/software:
Hello
I am developing wireless ultrasound equipment using the AFE5832LP.
When power is supplied and the AFE5832LP is initialized, the RX function operates normally.
However, when I power on the AFE5832LP only during the scan phase (32 ms) and turn off the power during the wireless transmission phase (100 ms), noise appears in the ultrasound image.
Initially, there is no noise, but after heating, noise appears on the right side of the image. During wireless transmission, only the power to the wireless module is turned on.
The reason for operating in this manner is to reduce heat generation.
When the power is kept on continuously, this issue does not occur.
Additionally, since no problem is observed when applying a ramp pattern, it seems unlikely that the issue lies beyond the ADC stage.
I would like to ask about the possible cause of this noise under these conditions.
Thanks.
