CRBV55CL-0640-0690

Overview

The Crystek Corporation CRBV55CL-0640-0690 is a Voltage Controlled Oscillator (VCO) designed for RF applications. It operates within a frequency range of 640 MHz to 690 MHz, with a center frequency of 665 MHz. The device utilizes a tuning voltage range of 0.5 V to 4.5 V. Output power specifications vary between 3.16 mW and 7.94 mW, corresponding to approximately -5 dBm to -1 dBm. Typical second harmonic suppression is rated at -12 dBc. The component is housed in a Redbox package.

Feature Summary

• Voltage-controlled operation across the 640 MHz to 690 MHz band
• Integrated oscillator circuitry within a compact Redbox enclosure
• Standard DC tuning voltage interface from 0.5 V to 4.5 V

Applications

• RF signal generation modules
• Frequency synthesis systems
• Wireless communication transceivers

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Crystek Corporation or authorized distributors before procurement. Ensure that the Redbox package dimensions align with the target PCB footprint design. Confirm that the required output power levels and harmonic suppression meet the system's interference requirements. Cross-reference the part number suffixes to ensure compatibility with existing inventory standards.

Selection Notes

Select this model when a fixed frequency range centered at 665 MHz is required. Consider the Redbox form factor for space-constrained designs. Evaluate the tuning sensitivity against the available control voltage resolution in the host system. Compare the typical output power against the needs of subsequent amplifier stages or mixers.

Part Context

This component belongs to the Crystek CRBV55CL series of Voltage Controlled Oscillators. The series offers various frequency bands tailored for different RF applications. The CRBV55CL-0640-0690 specifically targets the UHF band near 665 MHz. It shares the standard Redbox packaging characteristics common to this product line, ensuring mechanical consistency across similar frequency variants.

Replacement Considerations

Direct substitutes include other Crystek models within the CRBV55CL family, such as the CRBV55CL-0600-0880 or CRBV55CL-0575-0675, provided the frequency range differences are acceptable for the application. Verify pinout compatibility and electrical parameter overlaps before substitution.
