Frequently Asked Questions
What supply voltage do these clock generators require?
They operate on a single 3.3V supply, with a recommended range of 3.0V to 3.6V for most models.
How can I select different output frequencies?
Use the SEL pin to switch between available output frequencies for the specific model.
What package type is used for these generators?
They use a micro miniature HVSOF6 package, more compact than standard oscillators.
How do I enable the power-down function?
Use the OE pin to enable the power-down function to reduce current consumption.
