CVCO55BE-1650-2050

Overview

The CVCO55BE-1650-2050 is a Voltage Controlled Oscillator from the CVCO55 series by Crystek Corporation. It operates within a frequency range of 1650 MHz to 2050 MHz, with a center frequency of 1750 MHz. The device utilizes a tuning voltage range of 0.5 V to 10 V and requires a supply voltage of 8 V. Key electrical specifications include a typical phase noise of -118 dBc/Hz, output power of -5.0 ±1 dBm, and a second harmonic level of -20 dBc. Current consumption is limited to a maximum of 40 mA, with a pushing factor of 0.5 MHz/V. The component is housed in a 16-QFN package measuring 12.70 mm x 12.70 mm x 5.59 mm.

• Features low phase noise performance suitable for precision RF applications.
• Designed with a compact surface-mount QFN package for efficient PCB integration.

Applications

• RF signal generation in communication systems
• Local oscillator sources in receiver architectures
• Test and measurement equipment requiring stable frequency synthesis

Procurement Notes

Verify the specific suffix and revision level when ordering, as Crystek part numbers may vary slightly based on packaging or environmental compliance updates. Confirm that the required tuning voltage range (0.5 V to 10 V) matches your system's control circuitry capabilities. Ensure the 8 V supply requirement is supported by your power design. Cross-reference the datasheet for the latest RoHS3 compliance status and thermal characteristics before finalizing procurement.

Selection Notes

Select this model if your application requires a VCO covering the 1.65 GHz to 2.05 GHz band with moderate output power. Consider the 0.5 V to 10 V tuning sensitivity when designing the control loop bandwidth. The 12.7 mm square footprint dictates board space allocation. Evaluate the -20 dBc second harmonic specification against your filtering requirements to determine if additional harmonic suppression components are necessary for your specific EMI constraints.

Part Context

This component belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series is characterized by its use of standard QFN packages and operation across various RF bands. The CVCO55BE-1650-2050 specifically targets higher frequency applications compared to lower-band variants in the same family, offering a balance between size and performance for mid-range RF designs.

Replacement Considerations

Direct substitutes within the CVCO55 series include models such as CVCO55BE-1650-1850 for narrower bandwidth needs or CVCO55CC-0444-0485 for significantly lower frequency operations. Verify pinout compatibility and thermal pad connections when swapping between different frequency ranges within the same package type to ensure mechanical and electrical interchangeability.
