Procurement Notes

Verify the specific part number CVCO55CC-1750-1810 against official Crystek documentation to ensure compatibility with system requirements. Confirm that the operating voltage and tuning range align with the design specifications. Check for any recent revisions or updates to the datasheet that may affect performance characteristics or pin configurations before finalizing procurement decisions.

Selection Notes

Select this component when a wide tuning range and high stability are required in the 1.75 GHz to 1.81 GHz band. Consider the 8 V supply requirement and 1 V to 10 V tuning voltage when designing the control circuitry. Ensure the thermal environment supports the specified operating temperature range. Evaluate the output power and harmonic levels against system sensitivity requirements.

Part Context

This model belongs to Crystek's Coaxial Resonator Oscillator (CRO) line, which is distinct from standard quartz crystal oscillators. The CRO series utilizes coaxial cavity designs to achieve superior phase noise performance and frequency stability compared to traditional LC-based VCOs. This specific part is engineered for microwave frequencies, offering a balance of tunability and spectral purity for advanced RF applications.
