CVCO55CL-0640-0690

Overview

The CVCO55CL-0640-0690 is a voltage-controlled oscillator from Crystek Corporation designed for microwave applications. It operates within a frequency range of 640 to 690 MHz, with a center frequency of 665 MHz. The device requires a supply voltage of 5V and accepts a tuning voltage between 0.3 V and 4.7 V. It features a maximum current consumption of 25 mA and delivers an output power of 3±3 dBm. Typical phase noise is -108 dBc/Hz, with second harmonic suppression at -12 dBc. The unit functions across a temperature range of -40°C to 85°C and is housed in a 16-QFN package measuring 12.70mm x 12.70mm.

Feature Summary

• Integrated tuning voltage interface for frequency modulation
• RoHS compliant lead-free construction

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct frequency range and pinout configuration. Confirm that the procurement channel provides genuine components with traceable origin. Check for moisture sensitivity level compliance if storage conditions require strict environmental controls. Ensure the supplier offers valid quality certifications matching the component's RoHS status.

Selection Notes

Select this component when a fixed 640-690 MHz range is required. Evaluate the 5V supply constraint against system power budgets. Consider the 16-QFN package dimensions for PCB layout compatibility. Assess thermal performance requirements against the -40°C to 85°C operating limit. Verify that the tuning voltage range aligns with available control circuitry outputs.

Part Context

This model belongs to the CVCO55CL series of voltage-controlled oscillators manufactured by Crystek Corporation. The series utilizes a standardized surface-mount package design. Variants within the family differ primarily in their specified frequency ranges while maintaining similar electrical characteristics and physical footprints.

Replacement Considerations

Direct substitutes must match the 640-690 MHz frequency range and 16-QFN package. Cross-reference part numbers such as CVCO55CL-0600-0660 or CVCO55CL-0690-0740 only if adjacent frequency bands are acceptable. Verify pin compatibility before substitution.
