Procurement Notes
Verify the specific ordering suffix against official Crystek documentation to ensure correct pinout and connector configuration. Confirm that the required control voltage range aligns with system design constraints before procurement. Ensure environmental specifications meet operational temperature requirements.
Selection Notes
Select this component when a wide tuning range from 1.22 GHz to 2.25 GHz is required. Consider the 5 V supply requirement and SMA interface compatibility during circuit design. Evaluate the pushing figure and harmonic suppression metrics against system noise and spectral purity requirements.
Part Context
This part belongs to the CRBV55 RedBox series of Voltage Controlled Oscillators manufactured by Crystek Corporation. The series provides modular oscillator solutions designed for integration into RF systems requiring precise frequency control and stable output characteristics across defined temperature ranges.
Replacement Considerations
Consult official manufacturer cross-reference lists for verified substitutes. Generic equivalents may not match the specific SMA connector configuration or control voltage characteristics.
