CVCO55CL-0200-0400

Overview

The Crystek CVCO55CL-0200-0400 is a Voltage Controlled Oscillator (VCO) operating within a frequency range of 200 to 400 MHz, with a center frequency of 300 MHz. It utilizes a 16-QFN package variant measuring 12.70mm x 12.70mm x 5.59mm. The device requires a 5V supply voltage and accepts a tuning voltage from 0 V to 5 V. Key electrical specifications include a maximum current consumption of 25 mA, output power of 3 ±3 dBm, typical phase noise of -108 dBc/Hz, and a pushing factor of 0.5 MHz/V. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides stable voltage-controlled oscillation within the 200 to 400 MHz band
• Features low phase noise performance for signal integrity
• Designed for surface-mount integration in compact layouts

Applications

• Frequency synthesis systems
• Wireless communication transceivers
• Test and measurement instrumentation

Procurement Notes

Verify that the specific part number matches the required frequency range and package dimensions. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Ensure the design supports the specified 5V supply and 0-5V tuning voltage requirements. Check for any specific handling instructions related to the QFN package during soldering.

Selection Notes

Select this component when a 300 MHz center frequency with a 200-400 MHz tuning range is required. Consider the -108 dBc/Hz phase noise specification for applications demanding high spectral purity. The 16-QFN footprint must align with the PCB layout constraints. Evaluate the 25 mA current draw against available power budget constraints in the target system.

Part Context

This model belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series offers various frequency ranges tailored for different RF applications. The CVCO55CL-0200-0400 specifically targets the 200-400 MHz segment, providing a standardized solution for designers needing reliable VCO performance in a small surface-mount package.

Replacement Considerations

Direct substitutes within the same series include CVCO55CL-0184-0190, CVCO55CL-0189-0199, and CVCO55FL-0183-0219, though these operate at different frequencies. Cross-model replacements require careful verification of pin compatibility, supply voltage, and frequency specifications to ensure functional equivalence.
