Overview
The CVCO55CC-1680-1680 is a Voltage Controlled Oscillator (VCO) manufactured by Crystek Corporation, operating at a center frequency of 1680 MHz. It utilizes a coaxial resonator design to deliver stable oscillation across a tuning voltage range of 0.5 VDC to 4.5 VDC. The device provides an output power of 2.5 dBm with a typical second harmonic level of -8 dBc. Designed for high-performance applications, it features a tuning sensitivity of 9 MHz/V and operates on a maximum supply voltage of 5 V.
Feature Summary
- Coaxial resonator architecture for enhanced stability
- Wide voltage-controlled tuning range from 0.5 VDC to 4.5 VDC
- High output power capability at 2.5 dBm
- Compact surface-mount package design
Applications
- Microwave communication systems
- Frequency synthesis circuits
- Test and measurement equipment
- Radar subsystems
Procurement Notes
Verify the specific ordering suffix against the official Crystek datasheet to ensure correct frequency and tolerance specifications. Confirm RoHS compliance status and lead-free requirements prior to procurement. Cross-reference the pinout diagram with your PCB layout to guarantee proper electrical connections. Validate that the supply voltage does not exceed the 5 V maximum rating during system integration.
Selection Notes
Select this component when a 1680 MHz center frequency is required with precise voltage control. The 9 MHz/V tuning sensitivity allows for linear frequency adjustment over the specified voltage range. Consider the 2.5 dBm output power for direct driving of subsequent stages without additional amplification. Ensure the application environment supports the operational temperature range defined in the technical specifications.
Part Context
This model belongs to the CVCO55 series of Voltage Controlled Oscillators from Crystek Microwave. The series focuses on microwave frequency generation using coaxial resonator technology. These devices are engineered for low phase noise and high spectral purity. The CVCO55CC variant specifically denotes the coaxial construction and package style used in this product line.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult Crystek Corporation directly for potential cross-references or updated series replacements. Verify functional compatibility if considering alternative manufacturers.
