VX-700 Voltage Controlled Crystal Oscillators (VCXO)
The VX-700 is a Voltage Controlled Crystal Oscillator that operates at the fundamental frequency of the internal HFF crystal. The HFF crystal is a high-Q quartz device that enables the circuit to achieve low phase jitter performance over a wide operating temperature range. The VX-700 is housed in an industry standard hermetically sealed LCC package and available in tape and reel.
