Crystal Oscillator
FXO-31F
Miniature Clock Crystal Oscillator
■Features
¡It is a compact and thin ceramic package with a metalized lead for surface mounting
that is able to be automatically loaded.
¡Reflow soldering is possible.
¡CMOS, TTL IC direct drive is possible. Depending upon the frequency band, there
is also a crystal oscillator with a CMOS-IC with a tri-state function built in.
¡Use in the broad frequency band from 1.8MHz to 50MHz is possible.
