CVCO55BE-1770-1830

Overview

The CVCO55BE-1770-1830 is a voltage-controlled oscillator from the CVCO55 series manufactured by Crystek Corporation. It features a center frequency of 1770 MHz with an operating range spanning 1770 to 1830 MHz. The device operates on a 5V supply and accepts a tuning voltage between 0.3 V and 4.7 V. Key electrical specifications include a typical output power of 2.5 ±2.5 dBm, phase noise of -120 dBc/Hz, and second harmonic suppression of -15 dBc. It draws a maximum current of 35 mA and exhibits a pushing factor of 1 MHz/V. The component is housed in a 16-QFN package measuring 12.70mm x 12.70mm x 5.59mm.

Feature Summary

• Provides stable voltage-controlled oscillation within the specified frequency band
• Delivers consistent output power with defined harmonic suppression characteristics
• Operates reliably across a wide industrial temperature range

Applications

• Wireless communication systems requiring precise frequency control
• Test and measurement equipment utilizing signal generation
• RF receiver and transmitter architectures

Procurement Notes

Verify the exact part number against official Crystek Corporation documentation to ensure compatibility with system requirements. Confirm that the 16-QFN package dimensions and pinout match the design layout. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the supply voltage and tuning voltage ranges align with the host circuit capabilities before integration.

Selection Notes

Select this component when a fixed center frequency near 1770 MHz is required with minimal tuning flexibility. Consider the 12.7mm square footprint for PCB space constraints. Evaluate the -120 dBc/Hz phase noise specification against system sensitivity requirements. Verify that the 35mA current draw fits within the available power budget for the application environment.

Part Context

This model belongs to the CVCO55 series of voltage-controlled oscillators produced by Crystek Corporation. The series offers various frequency options packaged in compact surface-mount formats. These components are designed for applications demanding reliable RF signal generation with standardized electrical interfaces and mechanical profiles suitable for automated assembly processes.

Replacement Considerations

Consult the official CVCO55 selector guide for alternative frequencies or packages within the same series. Cross-reference specific parameters such as phase noise and output power when evaluating substitutes. Ensure any replacement maintains compatibility with the 16-QFN form factor and 5V supply requirement.
