Board Layout Considerations
TheCLK1andCLK2outputs aresurroundedwithsupply
pins
(GND(514),Vcc(712).
decouple these supplies with a 0.1uF very close to the
pins. The positive supply (7,12,15) and ground pins
(4,5,14) can all be connected to the Digital Supply and
Ground.
The internal VCO has its proper supply’s pins (GND 9,
Vcc 10) these supply pins have to be decoupled by a
0.1uF capacitor and should be connected to an Analog
It
is
recommended
to
Supply if possible. If there is no Analog Supply, then
connect these pins as close as possible to the supply
source.
If the layout is done with separate layers for the supplies,
cut an island under the XTT8000 such that no current
flowsunderthecircuit.Ithasbeenobservedthatcoupling
can occur because heavy digital currents are flowing
under the locations of the XRT8000.
