TYPICAL APPLICATION EXAMPLE
OPERATIONAL NOTES:
*
VCO is assumed AC coupled.
**
R
IN 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 power level. The fin RF impedance ranges from 40 to 100. The fin IF impedances are
higher.
***

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
IN may be AC or DC coupled. AC coupling is recommended be-
cause the input circuit provides its own bias. (See Figure below)
**** Adding RC filter to the V
CC line is recommended to reduce loop-to-loop noise coupling.
—
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.
