Circuit Board Design Rules
The following circuit board design rules are suggested:
•
•
Crystals and Resonators
Crystals and ceramic resonators (Figure 16) should exhibit
the following characteristics to ensure proper oscillation:

Crystal Cut
Mode
Crystal Capacitance
Load Capacitance
Resistance
To prevent induced noise, the crystal and load capaci-
tors should be physically located as close to the
Z8Plus as possible.
Signal lines should not run parallel to the clock oscil-
lator inputs. In particular, the crystal input circuitry

Depending on the operation frequency, the oscillator may
require additional capacitors,
