CVCO33CL-0390-0410

Overview

The CVCO33CL-0390-0410 is a voltage-controlled oscillator manufactured by Crystek Corporation. It operates within a frequency range of 390 MHz to 410 MHz, centered at 400 MHz. The device requires a supply voltage between 5.25 V and higher, with a control voltage range of 0.5 V to 4.5 V. It features a load capacitance of 100 pF and delivers an output power of 0 ±3 dBm. Typical second harmonic suppression is -12 dBc. The component is housed in a compact SMD package measuring 0.3 x 0.3 inches.

Feature Summary

• Voltage-controlled operation across a defined microwave frequency band
• Compact surface-mount design for space-constrained applications
• Standardized control voltage interface for integration

Applications

• Microwave communication systems
• Frequency synthesis circuits
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix against the official Crystek datasheet to ensure correct pinout and electrical characteristics. Confirm that the required load capacitance matches the system design specifications. Check RoHS compliance status if environmental regulations apply to the end product. Ensure the supply voltage requirements align with the available power rails in the target application circuit.

Selection Notes

Select this component when a fixed frequency range near 400 MHz is required with voltage tuning capability. Consider the 0.3 x 0.3 inch footprint for PCB layout constraints. Evaluate the -12 dBc typical second harmonic performance against system linearity requirements. Verify that the 100 pF load capacitance requirement does not necessitate additional external components that could affect phase noise or stability.

Part Context

This part belongs to the CVCO33 series from Crystek Corporation, which specializes in frequency control products. The series includes various models covering different frequency bands and package sizes. Crystek manufactures both quartz-based resonators and microwave frequency products. This specific model targets applications requiring stable oscillation in the UHF/microwave range with minimal form factor.

Replacement Considerations

Consult the official Crystek cross-reference documentation for verified substitute part numbers. Direct replacements must match the 390-410 MHz frequency range and compatible control voltage specifications. Ensure any alternative maintains similar package dimensions and electrical parameters to avoid redesigning the host circuit board.
