CVCO55CL-0920-0980

Overview

The CVCO55CL-0920-0980 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation. It operates within a frequency range of 920 MHz to 980 MHz, utilizing a control voltage span from 0.3 VDC to 4.9 VDC. The device features a tuning sensitivity (Kvco) of approximately 120 MHz/V and delivers an output power of +7 dBm typical. Phase noise performance is rated at -116 dBc/Hz at a 10 kHz offset. It functions on a single 5 VDC supply with a maximum current consumption of 27 mA. The unit is housed in a compact 0.5 x 0.5 inch surface mount package.

Procurement Notes

Verify the specific suffix designation against official Crystek documentation to ensure correct pinout and tuning curve specifications. Confirm that the required operating temperature range aligns with the component's industrial rating. Cross-reference the control voltage requirements with system-level loop filter designs to guarantee stability. Ensure that the supply voltage tolerance matches the device's specified input limits to prevent performance degradation or damage during operation.

Selection Notes

Select this model when a fixed center frequency near 950 MHz is required with moderate tuning bandwidth. Consider the Kvco value for loop filter design to balance lock time and phase noise performance. Evaluate the output power level against downstream amplifier requirements. Verify compatibility with available control voltage ranges in the host system. Assess the physical package constraints against the PCB layout requirements for optimal thermal and electrical performance.

Part Context

This component belongs to the CVCO55 series of voltage controlled oscillators produced by Crystek. The series offers various frequency bands tailored for different RF applications. The CVCO55CL variant specifically targets the lower microwave frequencies. These devices are designed for reliability and consistent performance in commercial and industrial environments. They represent a standardized solution for frequency synthesis needs in modern communication hardware.

Replacement Considerations

Direct substitutes include other Crystek models within the CVCO55 family covering similar frequency ranges, such as CVCO55CL-0925-0970. Ensure any replacement maintains identical pin configurations and electrical parameters. Verify that alternative parts meet the same phase noise and output power specifications. Check for availability of equivalent packages to facilitate direct board upgrades without redesign.
