Overview
The CVCO55CLS-0954-0980 is a surface-mount voltage-controlled oscillator (VCO) manufactured by Crystek Corporation. It operates within a frequency range of 954 MHz to 980 MHz and utilizes a QFN-16 package. The device requires a supply voltage of 5.25 V and accepts a tuning voltage range from 300 mVDC to 3 VDC. Key electrical specifications include an output power of approximately 0 dBm, a tuning sensitivity of 1 MHz/V, and a load capacitance of 50 pF. The unit supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Surface-mount design with QFN-16 package for compact integration
- Wide operational temperature range suitable for industrial environments
- Low phase noise performance with specified harmonic suppression
Applications
- Wireless communication systems requiring stable local oscillators
- Test and measurement equipment needing precise frequency generation
- RF signal processing circuits demanding low phase noise
Procurement Notes
Verify the specific suffix codes against official Crystek documentation to ensure correct frequency and package configuration. Confirm that the required supply voltage and tuning voltage ranges align with system design constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure thermal management strategies accommodate the specified operating temperature range during operation.
Selection Notes
Select this component when a fixed frequency range between 954 MHz and 980 MHz is required in a small form factor. Consider the 5.25 V supply requirement and 300 mV to 3 V tuning input when designing control circuitry. Evaluate the phase noise and harmonic suppression specifications against system sensitivity requirements. Compare the QFN-16 footprint against available PCB space constraints.
Part Context
This part belongs to the CVCO55 series of voltage-controlled oscillators from Crystek Corporation. The series offers various configurations including high-frequency, ultra-high-frequency, narrow-band, and wide-band variants. The CLS suffix typically denotes specific frequency and package characteristics within this family. These components are designed for applications requiring reliable RF signal generation in compact electronic devices.
Replacement Considerations
Direct substitutes must match the 954-980 MHz frequency range, QFN-16 package, and 5.25 V supply voltage. Verify equivalent phase noise and harmonic suppression levels to maintain system performance. Cross-reference pinouts and tuning voltage ranges to ensure compatibility with existing control circuits without redesign.
