Overview
The CVCO55CC-1372-1427 is a voltage-controlled oscillator (VCO) manufactured by Crystek Corporation, designed for UHF frequency applications. It operates within a tuning range of 1372 MHz to 1427 MHz, with a center frequency of 1399.5 MHz. The device requires a supply voltage of 5V and accepts a tuning voltage between 0.3 V and 4.7 V. Key electrical specifications include an output power of 3 dBm, a typical second harmonic level of -15 dBc, and a current rating of 25 mA. The phase noise performance is specified at -112 dBc/Hz.
Feature Summary
- Voltage-controlled operation utilizing coaxial resonator technology for stable frequency generation
- Designed for high stability in UHF band wireless communication systems
- Integrated design supporting direct integration into RF signal chains
Applications
- Wireless communication systems requiring frequency agility
- UHF band signal generation circuits
- RF test and measurement equipment
Procurement Notes
Verify the manufacturer part number CVCO55CC-1372-1427 against official Crystek documentation to ensure authenticity. Confirm that the received component matches the specified frequency range of 1372–1427 MHz and the 5V supply requirement. Check for physical integrity and correct pinout alignment before integration into circuit designs.
Selection Notes
Select this component when a fixed-frequency oscillator is insufficient and voltage-tunable output is required in the 1.37–1.43 GHz range. Consider the 25 mA current draw and 5V supply constraint during power budgeting. Ensure the tuning voltage interface supports the 0.3–4.7 V control range for proper frequency modulation.
Part Context
This model belongs to Crystek’s CVCO series of voltage-controlled oscillators, which are engineered for microwave and radio frequency applications. The series utilizes quartz-based or coaxial resonator technologies to provide precise frequency control. Crystek manufactures these components through its dedicated frequency control divisions, focusing on stability and low phase noise characteristics.
Replacement Considerations
Cross-reference with other Crystek CVCO models sharing the same form factor and electrical parameters if availability is constrained. Verify that substitute parts maintain the 1372–1427 MHz tuning range and compatible supply voltages to ensure circuit compatibility without redesign.
