Procurement Notes
Verify the specific part number against official Crystek Corporation datasheets to ensure compatibility with system requirements. Confirm that the operating voltage and tuning range align with your design constraints. Check for any updated revision history or pinout configurations before integration. Ensure sourcing channels provide genuine components to maintain signal integrity and reliability in critical RF applications.
Selection Notes
Select this component when a fixed frequency range between 445 MHz and 508 MHz is required. Consider the 5 V supply requirement and 40 mA current draw during power budgeting. Evaluate the -117 dBc/Hz phase noise specification against system sensitivity needs. The SMD package size should be compatible with the available PCB footprint and assembly processes.
Part Context
This model belongs to the CVCO55CC series of coaxial resonator VCOs from Crystek Corporation. These devices are designed for applications requiring precise frequency control and stability. The series typically offers various frequency ranges tailored for different RF bands, maintaining consistent packaging and interface characteristics across the lineup.
Replacement Considerations
Direct substitutes may include other models within the CVCO55CC series with matching frequency ranges. Verify pin compatibility and electrical parameters such as phase noise and tuning sensitivity before substitution. Cross-reference with Crystek's official replacement guides for validated alternatives.
