CVCO55CL-0805-0900

Overview

The CVCO55CL-0805-0900 is a voltage-controlled oscillator (VCO) from Crystek Corporation, operating within a frequency range of 805 MHz to 900 MHz with a center frequency of 852.5 MHz. It requires a supply voltage of 5 V and accepts a tuning voltage between 0.5 V and 5 V DC. The device draws a maximum current of 20 mA and delivers an output power of 2 ±3 dBm. Typical phase noise is specified at -108 dBc/Hz, while the second harmonic is typically -15 dBc. It functions reliably in temperatures ranging from -40°C to +85°C and is housed in a 16-QFN package measuring 12.70 mm x 12.70 mm.

Procurement Notes

Verify that the specific part number CVCO55CL-0805-0900 matches the required frequency range and package type before ordering. Confirm compatibility with the system's 5 V supply voltage and tuning voltage requirements. Ensure that the procurement channel provides original manufacturer documentation to guarantee component authenticity and traceability. Check for any specific handling instructions related to the QFN package during assembly.

Selection Notes

Select this component when a wide tuning range around 850 MHz is required alongside industrial temperature stability. Consider the 20 mA current consumption and 2 dBm output power against system power budget constraints. Evaluate the -108 dBc/Hz phase noise specification against the application's sensitivity requirements. Ensure the 16-QFN footprint aligns with existing board layout capabilities and reflow soldering profiles.

Part Context

This model belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series offers various frequency bands tailored for different RF applications. The CVCO55CL variant specifically denotes components designed for extended temperature operation, distinguishing it from commercial grade parts. This family emphasizes compact size and reliable performance for modern wireless devices.

Replacement Considerations

Direct substitutes within the same series include CVCO55CC-0787-0805, though it operates at a different frequency band (787-805 MHz). Other CVCO55 models may share the same package but differ significantly in frequency and electrical characteristics. Verify all parameters carefully when cross-referencing datasheets for alternative parts.
