CVCO55CL-1188-1212

Overview

The CVCO55CL-1188-1212 is a voltage-controlled oscillator (VCO) manufactured by Crystek Corporation, designed for surface-mount applications. It operates within a frequency range of 1188 MHz to 1212 MHz, centered at 1200 MHz. The device utilizes a tuning voltage range of 0 V to 8 V and requires a supply voltage of 5 V. It delivers an output power of ±2 dBm with a typical second harmonic suppression of -20 dBc. The component is housed in a 16-QFN variant package, measuring 0.5 x 0.5 inches, and supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Surface-mount design utilizing a compact 16-QFN package for efficient PCB integration
• Voltage-controlled operation enabled by a 0 V to 8 V tuning input range
• Integrated harmonic suppression capabilities to maintain signal purity

Applications

• RF signal generation in communication systems
• Frequency synthesis circuits
• Test and measurement equipment local oscillators

Procurement Notes

Verify the specific ordering suffix matches the required frequency tolerance and phase noise specifications. Confirm that the 16-QFN package dimensions align with the target footprint. Ensure the operating temperature range meets environmental requirements. Cross-reference the datasheet version to confirm electrical characteristics. Validate RoHS compliance status if restricted substances are prohibited in the assembly process.

Selection Notes

Select this component when a fixed center frequency near 1200 MHz is required with narrow tuning bandwidth. Consider the 5 V supply requirement and ±2 dBm output power level against system interface needs. Evaluate the thermal performance within the -40°C to 85°C range for the intended environment. Compare package size constraints against available board space. Assess phase noise performance if spectral purity is critical for the application.

Part Context

This part belongs to the CVCO55 series of voltage-controlled oscillators from Crystek Corporation. The series offers various frequency ranges tailored for microwave and RF applications. The CVCO55CL variant specifically denotes a low-phase-noise configuration suitable for demanding signal integrity requirements. Other models in the family differ primarily in center frequency and tuning range while maintaining similar package and supply characteristics.

Replacement Considerations

Direct substitutes include other Crystek CVCO55 series models with matching frequency ranges, such as CVCO55CL-1145-1210, provided the frequency specifications align with system requirements. Verify pinout compatibility and electrical parameters before substitution. Alternative manufacturers may offer functionally equivalent VCOs, but package and tuning voltage differences must be addressed.
