I need to generate a sine signal using a VCO (voltage controlled oscillator) in order to feed a PLL (Phase-locked loop). I need the output to be 12.8MHz and 3.3Vp-p.
I bought at RS a VCO reference 7099357
Despite the datasheet says: "Output Level (CMOS) Output High (Logic “1”) - - 90% VDD" I can only have an output of 1.2Vp-p. Output frequency is 12.8 as expected. The IC is being feed with 3.3V DC.
What feature do I need to look at in order to select a componen that has the desired 3.3Vp-p output? Do you know any specific component I should use?
This is how I'm connecting the IC
