OPERATIONAL NOTES:
*VCO is assumed AC coupled.
**R1 increases impedance so that VCO output power is provided to the load rather than the PLL. Typical values are 10Ω to 200Ω depending on the VCO power
level. f
RF impedance ranges from 40Ω to 100Ω.

**50Ω termination is often used on test boards to allow use of external reference oscillator. For most typical products a CMOS clock is used and no terminating
resistor is required. OSC
may be AC or DC coupled. AC coupling is recommended because the input circuit provides its own bias. (See Figure below.)
