Characteristics of CERALOCK^® Oscillation Circuits ⁵
2. Characteristics of the Oscillation Level
Fig. 5-2 shows examples of actual measurements of the
oscillation level versus temperature, supply voltage and
load capacitance (CL1, CL2). The oscillating amplitude is
required to be stable over a wide temperature range,
and temperature characteristics should be as flat as
possible. The graph titled Supply Voltage
Characteristics in Fig. 5-2 shows that the amplitude
varies linearly with supply voltage, unless the IC has an
internal power supply voltage regulator.
