CVCO55CC-1277-1433

Overview

The CVCO55CC-1277-1433 is a voltage-controlled oscillator (VCO) manufactured by Crystek Corporation. It operates within a frequency range of 1277 MHz to 1433 MHz, with a typical center frequency of 1355 MHz. The device utilizes a coaxial resonator design and accepts a control voltage input between 0.5 V and 15.0 V. It features a tuning sensitivity of -115 kHz/V and a phase noise specification of -115 dBc/Hz at a specific offset. The unit is housed in an 8.0±0.25 mm square package, specifically a 16-QFN variant, and is designed for operation across a temperature range of -30°C to +70°C.

Feature Summary

• Coaxial resonator construction for stable oscillation
• Wide control voltage range supporting flexible integration
• Compact surface-mount footprint suitable for dense PCB layouts

Applications

• Wireless communication systems requiring precise frequency synthesis
• Test and measurement equipment needing stable local oscillators
• RF transceiver modules in industrial applications

Procurement Notes

Verify the exact datasheet version and pinout configuration before integration, as specifications may vary slightly between production batches. Confirm that the control voltage supply matches the 0.5 V to 15.0 V requirement to prevent device damage. Ensure thermal management aligns with the -30°C to +70°C operating range for reliable performance in your specific environment.

Selection Notes

Select this component when a wide tuning range from 1277 MHz to 1433 MHz is required within a compact form factor. The coaxial resonator design offers advantages in phase noise performance compared to standard planar designs. Consider the 16-QFN package size constraints and the need for a high-voltage control interface when designing the surrounding circuitry.

Part Context

This part belongs to the CVCO55 series of voltage-controlled oscillators from Crystek Corporation. The series includes various models covering different frequency bands, such as the CVCO55CC-2328-2536 for higher frequencies. All units in this line share similar packaging and operational principles, differing primarily in their specified frequency ranges and tuning characteristics.

Replacement Considerations

Direct substitutes include other Crystek CVCO55 series variants like the CVCO55CC-1260-1400 if the frequency range differs but the package remains compatible. Cross-referencing with distributor databases for equivalent RoHS-compliant VCOs in 16-QFN packages is recommended for supply chain resilience.
