LMX2581: VccVCO supply limitation

Roni Barshan
Prodigy 20 points
Part Number: LMX2581


I would like to use LDO at 3.0v min for the VCCVCO input

all the rest of the supplies will have 3.3v

I am using the device at 2400 to 2500MHz 

what will be the degradation with performances at 3.0v input to VCCVCO?

    Hi Roni,

    We don't have data with this particular power supply configuration. 

    Generally speaking, we have internal LDO for the VCO and the LDO output voltage is less than 3.0V. So the LDO will work with a 3.0V input voltage.
