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 influencing the oscillator except at the
control input. The entire oscillator/filter section should be
surrounded 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 recommended 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 literature regarding use
and layout of oscillators which should be helpful.
