CVCO55CC-0775-0800

Overview

The CVCO55CC-0775-0800 is a Voltage Controlled Oscillator (VCO) from Crystek Corporation, designed for microwave frequency applications. It operates within a center frequency range of 775 MHz to 800 MHz, with a nominal center point of 787.5 MHz. The device utilizes a tuning voltage range of 0.3 V to 4.7 V to achieve frequency modulation. It delivers an output power of -5.0 ±2 dBm and exhibits a typical second harmonic suppression of -15 dBc. The component is housed in a surface-mount package measuring 12.7 mm by 12.7 mm.

Procurement Notes

Verify the specific part number CVCO55CC-0775-0800 against official Crystek documentation to ensure accuracy. Confirm that the required tuning voltage range of 0.3 V to 4.7 V aligns with your system design. Check for any available datasheets or application notes from the manufacturer to validate performance characteristics such as phase noise and tuning sensitivity before procurement.

Selection Notes

Select this component when a fixed frequency range between 775 MHz and 800 MHz is required. Ensure the system can provide the necessary 0.3 V to 4.7 V control voltage. Consider the -5.0 ±2 dBm output power and -15 dBc second harmonic specifications relative to downstream amplifier requirements. Verify that the 12.7 x 12.7 mm SMD footprint fits the PCB layout constraints.

Part Context

This model belongs to the CVCO55 series of Voltage Controlled Oscillators manufactured by Crystek Microwave, a division of Crystek Corporation. The series focuses on providing stable frequency sources for microwave industry applications. Other variants in the series offer different frequency ranges and tuning voltages, allowing for flexible system design across various RF bands.

Replacement Considerations

Direct substitutes may include other CVCO55 series parts with compatible frequency ranges, such as CVCO55BE-0325-0775, though pinout and electrical parameters must be verified. Cross-reference with other manufacturers' VCOs covering the 775-800 MHz range if form factor compatibility allows.
