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

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

Layout Hints:
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 a static sensitive device. It should be handled only at static free work stations.
