CDP6872

Low Power Crystal Oscillator

Description

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.
