CVCO55BE-1550-1650

Overview

The CVCO55BE-1550-1650 is a voltage-controlled oscillator from the Crystek CVCO55 series, designed for high-frequency applications. It operates within a frequency range of 1550 to 1650 MHz, with a center frequency of 1600 MHz. The device utilizes a tuning voltage range of 0.5 V to 4.5 V and requires a 5 V DC supply. Key performance metrics include a typical phase noise of -118 dBc/Hz and a second harmonic suppression of -20 dBc. It delivers an output power of -5.0 ±1 dBm with a maximum current consumption of 40 mA. The component is housed in a compact 16-QFN package measuring 12.7 mm x 12.7 mm, suitable for surface-mount assembly.

Feature Summary

• Provides stable voltage-controlled oscillation across a 100 MHz bandwidth centered at 1.6 GHz
• Features low phase noise characteristics for signal integrity
• Utilizes a standard 5V supply with wide tuning voltage input
• Designed for surface-mount integration in compact RF circuits

Applications

• RF communication systems requiring precise frequency synthesis
• Local oscillator stages in superheterodyne receivers
• Frequency modulation (FM) transmitter modules
• Test and measurement equipment signal generation

Procurement Notes

Verify the specific suffix 'BE' against official Crystek documentation to confirm pinout and electrical tolerances. Ensure compatibility with 5V logic levels and check RoHS3 compliance status for environmental regulations. Confirm lead times as manufacturing schedules may vary. Validate that the 16-QFN footprint matches your PCB design constraints before finalizing orders.

Selection Notes

Select this model when a 1.6 GHz center frequency is required with a 100 MHz tuning range. Consider the -5 dBm output power level for direct drive capabilities or need for amplification. Evaluate the -118 dBc/Hz phase noise against system sensitivity requirements. Ensure the operating temperature range of -40°C to 85°C meets environmental conditions.
