AFE4300: Can I duty cycle the 1MHz clock input to conserve power?

Jerome Villapando

Part Number: AFE4300

Hi, I am thinking of using an external clock source with a lower power mode enable pin (stops sending a clock). I will be running single-shot mode on the AFE4300 and I was wondering if I could turn off the external clock source whenever the AFE4300 is in power down mode.

Hi Jerome,

It is not recommended to turn off the clock, as it involves some recovery time.

Is this recovery time quantifiable? Not powering the clock at a fraction of the time will help greatly reduce power consumption, so I would like to know if this is feasible for our application. I will most likely be taking doing one IQ demodulation, and body weight scale conversion a second.
