Procurement Notes
Verify the specific part number CVCO55CC-1623-1678 against official Crystek Corporation documentation to ensure accuracy. Confirm that the required 5V supply and 0.3V to 4.7V tuning range match your system design. Check for any specific ordering suffixes or variations that may affect performance or pinout before finalizing procurement.
Selection Notes
Select this component when a fixed frequency range around 1.65 GHz is required with precise voltage control. Ensure the application can accommodate the 5V supply requirement and the 12.7mm x 12.7mm footprint. Consider the typical third harmonic suppression level if spectral purity is critical for the target RF environment.
