Procurement Notes
Verify the specific part number suffix against official Crystek documentation to ensure correct frequency and pinout compatibility. Confirm that the required tuning voltage range and supply voltage align with system design constraints before procurement. Cross-reference datasheet revisions to ensure all electrical parameters meet current application requirements.
Selection Notes
Select this component when a narrowband VCO near 560 MHz is required. Ensure the system can provide the specified minimum supply voltage and compatible tuning voltage range. Consider the package size and SMD mounting style for PCB layout integration. Verify thermal management needs based on the operating temperature range and power dissipation characteristics.
Part Context
This model belongs to the CVCO33CL series from Crystek Corporation, designed for microwave and RF applications. The series offers various frequency ranges tailored for communication and test equipment. Crystek specializes in frequency control products, including quartz crystals, oscillators, and VCOs, serving industries requiring precise frequency stability.
Replacement Considerations
Check Crystek's official substitution list for direct replacements. Models like CVCO33CL-0530-0600 share similar form factors but differ significantly in frequency range. Ensure any substitute matches the 559-561 MHz requirement and electrical specifications exactly.
