PCB Layout Considerations
It is highly recommended that power and ground
planes be used in layout The oscillator and filter
sections constitute a feedback loop and thus care
must be taken to avoid any feedback signal influ-
encing the oscillator except at the control input
The entire oscillatorfilter section should be sur-
rounded by copper ground to prevent unwanted
influences from nearby signals
Use separate
paths for analog and digital supplies keeping the
analog (oscillator section) as short and free from
spurious signals as possible Careful attention
must be paid to correct bypassing Keep lead
lengths short and place bypass caps as close to
the supply pins as possible If laying out a PCB
to use discrete components for the VCO section
care must be taken to avoid parasitic capacitance
at the OSC pins 3 and 5 and FILTER out (pin
7)
Remove ground and power plane copper
above and below these traces to avoid making a
capacitive connection to them It is also recom-
mended to enclose the oscillator section within a
shielded cage to reduce external influences on the
VCO as they tend to be very sensitive to ‘‘hand-
waving’’ influences the LC variety being more
sensitive than crystal controlled oscillators In
general the higher the operating frequency the
more important these considerations are
Self
contained VCXO or VCO modules are already
mounted in a shielding cage and therefore do not
require as much consideration in layout Many
crystal manufacturers publish informative litera-
ture regarding use and layout of oscillators which
should be helpful
