IN
Proper use of grounds and bypass capacitors is essential to achieve a high level of performance. Crosstalk between pins can be reduced by careful
board layout.
This is an electrostatic sensitive device. It should be handled only at static free work stations.
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
RF impedance ranges from 40Ω to 100Ω. f
