HA7210
Data Sheet
February 1999
File Number 3389.8
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.
