CVCO55CL-0370-0450

Overview

The CVCO55CL-0370-0450 is a voltage-controlled oscillator from the Crystek CVCO55 series, designed for RF applications. It operates within a frequency range of 370 to 450 MHz with a center frequency of 410 MHz. The device utilizes a 5V supply and accepts a tuning voltage between 0.5 V and 4.5 V. Key electrical specifications include a typical output power of 7 ±2 dBm, a second harmonic suppression of -4 dBc, and a phase noise of -118 dBc/Hz. It features a maximum current consumption of 40 mA and a pushing factor of 0.5 MHz/V. The component is housed in a 16-QFN package measuring 12.70mm x 12.70mm x 5.59mm and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides stable voltage-controlled oscillation across a 370–450 MHz frequency band
• Integrates low phase noise performance suitable for precision signal generation
• Utilizes a compact 16-QFN surface-mount package for efficient PCB integration

Applications

• RF signal generation in communication systems
• Local oscillator sources in receiver architectures
• Test and measurement equipment requiring precise frequency control

Procurement Notes

Verify that the specific part number matches the required frequency range and package type before ordering. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure that the supply voltage and tuning voltage requirements align with your system design constraints. Check for any specific handling instructions related to the QFN package during assembly.

Selection Notes

Select this model when a center frequency of 410 MHz is required with a wide tuning range. Consider the -4 dBc second harmonic specification for applications where harmonic filtering must be minimized. Evaluate the 40 mA current draw against power budget constraints. The 16-QFN form factor is appropriate for designs prioritizing space efficiency over through-hole mounting options.

Part Context

This component belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series offers various frequency ranges tailored for different RF needs. The CVCO55CL-0370-0450 specifically targets the VHF band, providing a balance between tuning range and spectral purity. It shares the same physical footprint as other variants in the family, facilitating potential design flexibility.

Replacement Considerations

Direct substitutes within the CVCO55 series may exist for different frequency bands, such as the CVCO55CC-0444-0485, though their electrical parameters differ significantly. Verify compatibility regarding pinout, thermal characteristics, and electrical specifications before swapping components. Generic replacements are not recommended due to the precise nature of oscillator frequencies and phase noise requirements.
