Oven Controlled Crystal Oscillator
NA-10 MHz-2500 series
2500 Series in 25.4x25.4mm DIP package
NA-10M-2500 series oscillators is designed for applications where space is at a premium
and good frequency stability is required. The oscillators can be used in many
communications applications. A choice of quartz resonators offers a variety of
performance versus cost options to fit most applications.
