APPLICATION NOTES
THERMAL STABILITY
The delay line used internally to develop the clock
signals in the DLO32F has a thermal coefficient
of 100ppm/C. For low frequency units, this is also
the thermal coefficient of the output frequency.
For higher frequency units, however, other
internal effects must be considered, and the
actual thermal coefficient may be somewhat
higher.
POWER SUPPLY BYPASSING
The DLO32F relies on a stable power supply to
produce a repeatable frequency within the stated
tolerances. A 0.1uf capacitor from VCC to GND,
located as close as possible to the VCC pin, is
recommended. A wide VCC trace and a clean
ground plane should be used.
