Procurement Notes

Verify the specific part number suffix against official Crystek documentation to ensure compatibility with required frequency tolerances and packaging options. Confirm RoHS compliance status and environmental classifications prior to procurement. Ensure that the supplier provides valid datasheets matching the exact model designation to avoid discrepancies in electrical parameters or pin configurations during integration.

Selection Notes

Select this component when a narrow bandwidth VCO near 1.85 GHz is required with moderate output power levels. Consider the 16-QFN footprint and thermal characteristics for PCB layout planning. Evaluate the tuning sensitivity and phase noise specifications against system requirements for signal purity. Ensure the control voltage range aligns with available drive circuitry capabilities within the target application environment.

Part Context

This oscillator belongs to the CVCO55 series, which offers various frequency ranges and package options from Crystek Corporation. The series is designed for general-purpose RF applications requiring reliable voltage-controlled frequency generation. Components in this family share similar form factors and operational principles, differing primarily in center frequency and specific tuning characteristics defined by their unique part numbers.

Replacement Considerations

Direct substitutes must match the 1.848–1.852 GHz frequency range, 16-QFN package, and 5V supply requirement. Verify equivalent phase noise and output power specifications before substitution. Cross-reference with other Crystek CVCO55 variants or comparable industry VCOs ensuring identical pinout and thermal properties to maintain board compatibility.
