CVCO55CM-0760-0870

Overview

The CVCO55CM-0760-0870 is a voltage-controlled oscillator (VCO) manufactured by Crystek Corporation, operating within a frequency range of 760 MHz to 870 MHz with a center frequency of 815 MHz. It features a tuning voltage range of 400 mVDC to 4.7 VDC and delivers an output power of 0 dBm ±2 dBm. The device exhibits a typical phase noise of -110 dBc/Hz and second harmonic suppression of -15 dBc. Electrical specifications include a maximum current consumption of 25 mA at a 5 V supply, a pull rate of 0.5 MHz/V, and a push sensitivity of 30 MHz/V. The component is housed in a surface-mount package measuring 12.7 mm x 12.7 mm x 5.59 mm.

Feature Summary

• Surface-mount voltage-controlled oscillator design for high-frequency signal generation
• Low phase noise performance suitable for precision communication applications
• Integrated harmonic suppression capabilities for cleaner spectral output

Applications

• Wireless communication systems requiring stable local oscillation
• Test and measurement equipment utilizing frequency synthesis
• Industrial control systems needing reliable RF signal sources

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to ensure compatibility with required tuning characteristics and frequency ranges. Confirm that the surface-mount package dimensions align with the target PCB layout constraints. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure supply chain availability matches project timelines, as distribution channels may vary. Validate electrical parameters against system requirements before integration.

Selection Notes

Select this component when a narrowband VCO operation between 760 MHz and 870 MHz is required. Consider the 0 dBm output power level for direct coupling or low-noise amplifier interfacing. Evaluate the 25 mA current draw against available power budgets in portable or battery-operated devices. The standard 5 V supply requirement simplifies power management design compared to lower voltage alternatives. Assess thermal performance within the specified operating temperature range for the intended environment.

Part Context

This part belongs to the CVCO55 series of voltage-controlled oscillators from Crystek Corporation. The series offers various frequency bands tailored for different RF applications. The CM variant typically denotes specific packaging and performance characteristics distinct from other series members like CX or CL. These components are designed for consistent performance across industrial and commercial temperature ranges.

Replacement Considerations

Direct substitutes require matching the 760-870 MHz frequency range and similar electrical parameters. Verify pinout compatibility and package dimensions for seamless PCB replacement. Cross-reference phase noise and harmonic suppression levels to maintain signal integrity. Consult Crystek Corporation for updated part numbers within the same family that may offer improved availability or enhanced specifications.
