RFPT700
-------
SMD Low Acceleration Sensitivity TCXO / TCVCXO.
-------
-------
A series of surface mountable Temperature Compensated Voltage Controlled Crystal
Oscillators (TCVCXOs) for applications where phase noise performance under vibration
is critical.
-------
Product description
-------
The RFPT700 TCVCXO uses Rakon's proprietary ASIC 'Pluto™', a single chip oscillator with
analogue compensation circuit, and a patented crystal resonator design, resulting in high
stability over a wide temperature range paired with typically 0.2ppb/g acceleration sensitivity.
