Temperature Compensated Crystal Oscillator
TX-707
TX-707
Description
The TX-707 Series TCXO combines innovative manufacturing and the latest technology to provide low phase noise and excellent
g-sensitivity. The fully hermetic assembly includes a dual crystal circuit to cancel opposing g-sensitivity vectors enclosed in a
5x7mm ceramic package.
