CVCO55CL-0467-0493

Overview

The CVCO55CL-0467-0493 is a surface-mount voltage-controlled oscillator (VCO) from Crystek Corporation, designed for narrow-band applications. It operates within a frequency range of 467 MHz to 493 MHz. The device features a compact SMD package measuring 0.50 inches square (12.7 x 12.7 mm). It supports a load capacitance of 100 pF and utilizes RoHS-compliant manufacturing processes. This component is part of the CVCO55CL series, which emphasizes low phase noise and low harmonics for high-performance RF signal generation.

Feature Summary

• Narrow bandwidth frequency range optimized for specific channel requirements
• Low phase noise performance for clear signal integrity
• Compact square surface-mount design for space-constrained layouts
• Low harmonic output to reduce spectral interference

Applications

• RF communication systems requiring stable local oscillators
• Test and measurement equipment needing precise frequency sources
• Wireless infrastructure components operating in UHF bands
• Satellite communication transceivers

Procurement Notes

Verify the exact frequency tolerance and control voltage specifications against the official Crystek datasheet before integration. Ensure that the PCB layout accommodates the 12.7 x 12.7 mm footprint and provides adequate thermal relief for the SMD package. Confirm RoHS compliance status if required by your supply chain regulations. Cross-reference the pinout diagram with your schematic to prevent connection errors during assembly.

Selection Notes

Select this model when a narrow tuning range between 467 MHz and 493 MHz is required. It is suitable for designs prioritizing low phase noise over wideband agility. Consider the 100 pF load capacitance requirement for impedance matching networks. Compare against wider band alternatives like the CVCO55CW series if broader frequency coverage is needed instead of spectral purity.

Part Context

This component belongs to the CVCO55 family, specifically the CL variant designated for narrow-band operations. The series includes options for high frequency (BE), ultra-high frequency (BH), and coaxial resonator (CC) configurations. The CVCO55CL series distinguishes itself by offering reduced harmonic content and enhanced stability compared to standard broadband VCOs, making it ideal for specialized RF applications.

Replacement Considerations

Direct substitutes include other CVCO55CL models with different frequency ranges, such as CVCO55CL-0470-0520, provided the frequency shift is acceptable. For wider bandwidth needs, consider the CVCO55CW series. Ensure any replacement maintains the same SMD footprint and electrical interface compatibility to avoid PCB redesign.
