LMK04828-EP: MIN/MAX datasheet values, design margin.

Dan Abbey

Part Number: LMK04828-EP

Hi team,

I'm working with a customer that is potentially interested in LMK04828-EP. Could you please help with the questions below:

Re: the datasheet parameter table on page 8, can you confirm that the max/min parameters are guaranteed over 3.15V < Vcc < 3.45V, -55C to 105C.

In our case the frequency of VCO0 is 2457MHz which is very close to the lower limit of the VCO0 for LMK04828-EP, do you have any concerns using the device so close to the VCO0 Min over -55C to 105C?

Thanks in advance

Dan

Hello Dan,

Yes, the min max numbers are across conditions. The typical numbers are at nominal voltage and room temp.

heh VCO frequency ranges are specified with some margin to accommodate the range of process voltage and temperature so as long as you are within the range there should be no issues.
