10kHz to 10MHz, Low Power Crystal

Oscillator

The HA7210 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 HA7210 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.
