Design Considerations
PS003807-1002
The Z8 uses a Pierce oscillator with an internal feedback circuit. The advantages
of this circuit are low cost, large output signal, low-power level in the crystal, stabil-
ity with respect to V
stray effects.)
One drawback is the requirement for high gain in the amplifier to compensate for
feedback path losses. Traces connecting crystal, capacitors, and the Z8 oscillator
pins must be as short and wide as possible. Short and wide traces reduce para-
sitic inductance and resistance. The components (capacitors, crystal, and resis-
tors) must be placed as close as possible to the oscillator pins of the Z8.
The traces from the oscillator pins of the integrated circuit (IC) and the ground
side of the lead capacitors must be guarded from all other traces (clock, V
system ground) to reduce cross-talk and noise injection. Guarding the traces is
usually accomplished by keeping other traces and system ground trace planes
away from the oscillator circuit and by placing a Z8 device V
the traces/components. The ground side of the oscillator lead capacitors must be
connected to a single trace to the Z8 V
any other system ground trace or components except at the Z8 device V
Not sharing the ground side of the oscillator lead capacitors is to prevent differen-
tial system ground noise injection into the oscillator.
