Part Number: CC1101-Q1

Hi,

This is about CC1101-Q1 receiver current consumption.

I found below description in CC1101-Q1 datasheet, the current value at 1.2kbps with DEM_DCFILT_OFF=0

I would like to know the current consumption with DEM_DCFILT_OFF=1

We assume the current difference between DEM_DCFILT_OFF=1 and 0 at 433MHz Receive mode, 38.4 kbps, input 20 dB above sensitivity limit as 22.2 – 18 = 4.2mA.

Is my understanding correct?

Based on that, can we estimate the MAX current consumption at 433MHz Receive mode, 1.2 kbps, input 20 dB above sensitivity limit, DEM_DCFILT_OFF=1 as 22 – 4.2 = 17.8 mA?

Best regards,

It gives an indication to what the max value will be for 1.2 kbps. But based on the datasheet numbers I can't guarantee that the current always will be lower than 17.8 mA since it's not measured as part of the C.
