VCO Buffer Amplifiers
as close to the VCC pin as possible. For long VCC lines
(inductive), it may be necessary to add additional
decoupling capacitors located farther away from the
device package.
Proper connection of the GND pins is essential to
achieving maximum reverse isolation. If the PC board
uses a topside RF ground, connect both GND pins
directly to it. For a board where the ground plane is not
on the component side, the best technique is to con-
nect the GND pins to the board with plated through-
holes (vias) to the ground plane, located as close to the
package as possible.
