Overview
The CVCO55CL-0760-0860 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation. It operates within a frequency range of 760 MHz to 860 MHz, with a center frequency of 810 MHz. The device utilizes a tuning voltage range of 300 mVDC to 4.7 VDC and requires a supply voltage of 2V. Key electrical specifications include a typical phase noise of -100 dBc/Hz at 1 Hz bandwidth, a second harmonic level of -15 dBc, and a tuning sensitivity of 40 MHz/V. The component is housed in an SMD package measuring 12.7 mm x 12.7 mm.
Feature Summary
- Provides stable voltage-controlled oscillation across the specified UHF band
- Features low phase noise performance for signal integrity
- Designed for surface-mount integration in compact circuits
Applications
- Wireless communication systems
- RF signal generation modules
- Test and measurement equipment
Procurement Notes
Verify the specific suffix CL against the official Crystek datasheet to confirm the exact tuning voltage range and supply requirements. Ensure the ordering documentation matches the required frequency tolerance and phase noise specifications. Confirm that the SMD package dimensions align with the target PCB footprint before finalizing procurement orders.
Selection Notes
Select this model when a 760-860 MHz VCO with a 2V supply is required. Compare the 40 MHz/V tuning sensitivity against system loop filter requirements. Evaluate the -100 dBc/Hz phase noise metric relative to application jitter constraints. Verify compatibility with the 300 mVDC minimum tuning voltage threshold.
Part Context
This component belongs to the CVCO55 series of Voltage Controlled Oscillators from Crystek Corporation. The series offers various frequency ranges and packaging options. The CVCO55CL variant specifically targets applications requiring a 2V supply and a 760-860 MHz output range, distinguishing it from other series members with different voltage or frequency parameters.
Replacement Considerations
The CVCO55CM-0760-0870 is a related part number within the same product family. Note that the CM variant typically specifies a 5V supply and a slightly different frequency range (760-870 MHz). Direct substitution requires verification of supply voltage compatibility and pinout alignment.
