Procurement Notes
Verify that the specific part number matches the required frequency range and package dimensions before procurement. Confirm that the supply voltage and tuning voltage specifications align with the target circuit design. Ensure that the manufacturer source is authorized to guarantee component authenticity and datasheet accuracy. Cross-reference the load capacitance requirements with system impedance matching needs.
Selection Notes
Select this component when ultra-low phase noise is critical for narrow band operations. Consider the 16-QFN package size constraints during PCB layout planning. Evaluate the 0.5 V to 10 V tuning voltage range against available control circuitry capabilities. Assess the 5 V minimum supply requirement against power budget limitations in the final assembly.
Part Context
This model belongs to the CVCO55CC series from Crystek Corporation, which specializes in frequency control products. The series focuses on coaxial resonator-based oscillators designed for high-performance microwave applications. Crystek provides these devices for industries requiring precise frequency stability and low noise figures in compact form factors.
Replacement Considerations
Consult official Crystek documentation for direct substitutes within the CVCO55CC family. Verify frequency compatibility and package dimensions when evaluating alternative models. Ensure that any replacement maintains the required coaxial resonator architecture for equivalent noise performance.
