Procurement Notes
Verify the exact part number CVCO55CL-0184-0190 against manufacturer documentation to ensure correct frequency range and pinout compatibility. Confirm RoHS3 compliance status if required by project specifications. Check datasheet for specific loading conditions and tuning curve linearity requirements before integration into final designs.
Selection Notes
Select this component when a low-power VCO is needed for the 184-190 MHz range. Consider the 7mA current draw and 0dBm output power relative to system needs. Ensure the 16-QFN footprint fits the PCB layout constraints. Compare phase noise and harmonic performance against alternative Crystek models if stricter spectral purity is required.
Part Context
This model belongs to the CVCO55 series of voltage-controlled oscillators from Crystek Corporation. The series offers various frequency ranges packaged in standard SMD formats. The CVCO55CL-0184-0190 specifically targets lower UHF frequencies compared to other variants in the same family, maintaining consistent packaging and electrical interface standards across the product line.
Replacement Considerations
Direct substitutes include other CVCO55 series parts with matching frequency ranges or compatible pinouts. Verify that replacement components maintain similar current consumption and output power levels. Cross-reference datasheets for thermal and electrical parameter alignment to ensure seamless integration without circuit redesign.
