CVCO55CL-1090-1145

Overview

The CVCO55CL-1090-1145 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation. It operates within a frequency range of 1090 MHz to 1145 MHz, with a center frequency of 1117.5 MHz. The device requires a 5V supply voltage and accepts a tuning voltage input between 0.3 V and 4.7 V. It is housed in a 16-QFN package variant measuring 12.70mm x 12.70mm x 5.59mm. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides stable voltage-controlled oscillation across the specified microwave frequency band
• Designed for operation under industrial temperature conditions
• Utilizes a compact surface-mount QFN package for efficient board integration

Applications

• Wireless communication systems requiring local oscillator signals
• Test and measurement equipment calibration sources
• Microwave receiver front-end architectures

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Crystek Corporation or authorized distributors before procurement. Confirm that the 16-QFN pinout matches the target PCB footprint design. Ensure the supply voltage tolerance aligns with the system power rail specifications to prevent operational instability.

Selection Notes

Select this model when a fixed frequency range near 1.1 GHz is required without external tuning components. Compare phase noise and harmonic performance against alternative VCOs if signal purity is critical. Verify that the 5V supply requirement fits within the available power budget of the host circuit design.

Part Context

This component belongs to the CVCO55 series of voltage-controlled oscillators from Crystek Corporation. The series offers various frequency ranges tailored for different microwave applications. The CVCO55CL-1090-1145 specifically targets the 1090-1145 MHz band, distinguishing it from lower or higher frequency variants within the same product family.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate other Crystek CVCO55 series models with matching frequency ranges. Cross-reference electrical parameters such as tuning voltage and supply current with potential alternatives from other manufacturers.
