Hi All,
Found this interesting device last week while looking for a basic PLL to
replace a crystal for an IF offset. Has anyone experimented with the
si570/si571 yet?

I built a kit and found that it wanders 50 Hz at 10MHz.

Hi All
Anybody know what its performance is like under vibration?

Just guessing here . . . poor
Unless it is a specifically G-hardened device, it is sure to be microphonic.

The trick of including a PLL in an oscillator package has been around for a
while.
The initial ones were programmed at the factory or distributor. The idea was
to avoid the long wait while they polished the crystal to your specific
frequency. They stocked them in a handful of frequencies
