HA7210
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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
