RFout Output Impedance
30073345
The impedance of the RFout pin varies as a function of frequency, VCO_DIV, OUTTERM, VCOGAIN, DIVGAIN, and frequency.
When in bypass mode (VCO_DIV = 1), the DIVGAIN word has no impact on the output impedance. When in divided mode
(VCO_DIV>1), the VCOGAIN has no impact on the output impedance. The above graphic shows how the input impedance varies
as a function of frequency for both the bypass and divided cases.
