Overview
The CVCO55CC-2122-2242 is a Coaxial Resonator Oscillator (CRO) manufactured by Crystek Corporation. It operates within a frequency range of 2122 MHz to 2242 MHz, with a center frequency of 2182 MHz. The device requires a supply voltage and features a control voltage range of 0.3 V to 4.9 V. It delivers an output power of 7 ±2 dBm and draws a maximum current of 40 mA. The component is housed in a 16-QFN package variant, measuring 0.220 inches (5.59 mm) in height. It supports an operating temperature range from -40°C to 85°C and exhibits typical second harmonic rejection of -15 dBc.
Feature Summary
- Utilizes coaxial resonator technology for stable oscillation
- Voltage-controlled operation via specified control voltage range
- Compact surface-mount packaging design
Applications
- Microwave frequency synthesis systems
- RF signal generation circuits
- Communication equipment local oscillators
Procurement Notes
Verify the specific ordering suffix against official Crystek documentation to ensure correct frequency tuning and electrical characteristics. Confirm that the 16-QFN package dimensions align with your PCB footprint requirements. Ensure supply voltage levels remain within specified limits to prevent damage. Check for any recent product lifecycle notices or obsolescence warnings directly from the manufacturer before placing orders.
Selection Notes
Select this component when a fixed frequency range around 2.1 GHz is required with voltage control capabilities. Consider the 7 dBm output power level for direct driving needs without additional amplification. Evaluate the thermal performance within the -40°C to 85°C range for your specific environment. Compare the 16-QFN form factor against available board space constraints relative to other VCO options.
Part Context
This part belongs to Crystek's Coaxial Resonator Oscillator series, designed for microwave applications. It complements their broader portfolio of quartz crystals, TCXOs, and standard VCOs. The CRO architecture offers distinct performance characteristics compared to traditional LC-based voltage controlled oscillators, providing stability suitable for precision frequency control tasks in professional RF systems.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult Crystek technical support for potential cross-references if this specific model becomes unavailable.
