CVCO55BE-1690-2062

Overview

The CVCO55BE-1690-2062 is a voltage-controlled oscillator from the Crystek CVCO55 series, designed for RF applications. It operates within a frequency range of 1690 MHz to 2062 MHz, with a center frequency of 1876 MHz. The device utilizes a tuning voltage range of 0 V to 5 V and requires a 5 V supply. Key electrical specifications include a typical output power of 5 ±2 dBm, a maximum current consumption of 20 mA, and a second harmonic suppression of -22 dBc. Phase noise is typically -118 dBc/Hz. The component is housed in a 16-QFN package measuring 0.500 inches by 0.500 inches (12.70 mm x 12.70 mm) with a height of 0.150 inches (3.81 mm).

Feature Summary

• Provides wide frequency coverage from 1690 MHz to 2062 MHz using a single 0 V to 5 V control voltage.
• Delivers stable RF output with typical phase noise performance suitable for precision timing applications.
• Features low current consumption and compact surface-mount packaging for efficient board space utilization.

Applications

• Wireless communication systems requiring precise frequency synthesis
• RF test and measurement equipment
• Satellite navigation receivers
• Point-to-point microwave links

Procurement Notes

Verify that the ordering suffix matches the required frequency range and pinout configuration. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the 16-QFN footprint dimensions align with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this model when a center frequency near 1876 MHz is required with a tuning span exceeding 300 MHz. Consider the 0 V to 5 V tuning range compatibility with your system's control voltage levels. Evaluate the -22 dBc second harmonic specification against your filtering requirements to determine if additional harmonic suppression circuitry is necessary.

Part Context

This component belongs to the CVCO55 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series offers various frequency options across different bands, all sharing similar physical dimensions and electrical characteristics. The CVCO55BE variant specifically addresses higher frequency ranges compared to other series members.

Replacement Considerations

Direct substitutes may include other Crystek CVCO55 models with adjusted frequency ranges, such as CVCO55CC-0444-0485 for lower frequencies. Cross-vendor replacements require careful verification of pinout compatibility, tuning voltage ranges, and thermal characteristics to ensure functional equivalence.
