CVCO55CL-0575-0675

Overview

The CVCO55CL-0575-0675 is a voltage-controlled oscillator from the Crystek CVCO55 series, designed for microwave applications. It operates within a frequency range of 575 MHz to 675 MHz, with a center frequency of 625 MHz. The device utilizes a tuning voltage range of 0.3 V to 4.7 V and requires a 5 V supply. Key electrical specifications include a typical output power of -5.0 ±1 dBm, phase noise of -118 dBc/Hz, and second harmonic suppression of -20 dBc. It draws a maximum current of 40 mA and exhibits a pushing factor of 0.5 MHz/V. The component is housed in a 16-QFN package measuring 12.70 mm x 12.70 mm.

• Test and measurement equipment
• Wireless infrastructure components

Procurement Notes

Verify the specific suffix CL against the official Crystek datasheet to confirm environmental compliance and pinout configuration. Ensure the ordering part number matches the required frequency range and package variant. Cross-reference the manufacturer's latest documentation to validate RoHS status and lead time requirements before finalizing procurement orders.

Selection Notes

Select this model when a fixed frequency range of 575-675 MHz is required with precise tuning control. Consider the -118 dBc/Hz phase noise specification for applications demanding high spectral purity. Evaluate the 12.7x12.7 mm footprint against available PCB space. Confirm that the 0.3-4.7 V tuning voltage aligns with the system's control interface capabilities.

Part Context

This component belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series is characterized by its integrated design, combining the oscillator circuitry into a single surface-mount package. This specific model represents one variant within the broader family, distinguished by its unique center frequency and tuning range parameters defined by the part numbering convention.

Replacement Considerations

Direct substitutes within the same series include CVCO55CC-0444-0485 for different frequency bands. Verify compatibility with CVCO55CL-0540-0560 if lower frequencies are acceptable. No other manufacturers offer identical pin-compatible replacements; alternative designs require schematic redesign.
