Procurement Notes

Verify the specific ordering suffix matches the required frequency tolerance and package variant. Confirm that the supplier provides official datasheets from Crystek Corporation to ensure component authenticity. Check for any specific handling requirements related to the QFN package during assembly.

Selection Notes

Select this model when a fixed frequency range between 434 MHz and 452 MHz is required. Ensure the system design supports the 1.5 V to 3.5 V tuning voltage input. Consider the 16-QFN footprint for PCB layout compatibility. Verify that the 18 dBm output power aligns with downstream circuit requirements without excessive amplification or attenuation.

Part Context

This component belongs to the CVCO55 series of voltage-controlled oscillators from Crystek Corporation. The series offers various frequency options tailored for different RF bands. The CVCO55CL-0434-0452 specifically targets the 434-452 MHz segment, providing a standardized solution for manufacturers needing precise frequency control in compact form factors.
