Description
A surface-mount
Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) for applications where phase noise performance under vibration is critical. The IQXT-312 is a single chip oscillator with an analogue compensation circuit, and a patented crystal resonator design, resulting in high stability over a wide temperature range paired with good acceleration sensitivity.
