CVCO55CC-2128-2128

Overview

The CVCO55CC-2128-2128 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation. It operates at a center frequency of 2.128 GHz with a tuning range of 2128 MHz to 2128 MHz. The device requires a minimum supply voltage of 5 V and features a load capacitance of 22 pF. It is housed in a QFN-16 package, measuring 0.500 inches L x 0.500 inches W (12.70mm x 12.70mm). The unit supports an operating temperature range from -40°C to +85°C and utilizes a control voltage range of 0.3 V to 4.7 V.

Feature Summary

• Provides stable microwave frequency generation within the specified 2.128 GHz band
• Operates reliably across industrial temperature extremes from -40°C to +85°C
• Utilizes a compact QFN-16 surface-mount package for efficient PCB integration

Applications

• Microwave communication systems requiring precise frequency synthesis
• Test and measurement equipment needing stable local oscillators
• Radar systems utilizing high-frequency signal generation

Procurement Notes

Verify that the specific part number matches the required frequency and package configuration. Confirm compatibility with the 5 V supply requirement and 0.3–4.7 V control voltage range. Ensure the QFN-16 footprint aligns with the design layout. Check for any suffix variations that may indicate different thermal or electrical specifications.

Selection Notes

Select this component when a fixed 2.128 GHz output is required with narrow tuning capabilities. Consider the 5 V supply constraint and QFN-16 package size during circuit design. Evaluate thermal management needs given the -40°C to +85°C operating range. Compare against other Crystek VCOs if broader tuning ranges or different frequencies are necessary.
