The CDP6872 is a very low power crystal-controlled oscillators
that can be externally programmed to operate between 10kHz
and 10MHz. For normal operation it requires only the addition
of a crystal. The part exhibits very high stability over a wide
operating voltage and temperature range.
The CDP6872 also features a disable mode that switches
the output to a high impedance state. This feature is useful
for minimizing power dissipation during standby and when
multiple oscillator circuits are employed.
