CVCO55CL-0393-0428

Overview

The CVCO55CL-0393-0428 is a voltage-controlled oscillator from the Crystek CVCO55 series, designed for applications requiring stable frequency generation. It operates within a frequency range of 393 MHz to 428 MHz, with a center frequency of 410.5 MHz. The device utilizes a tuning voltage range of 0.5 V to 4.5 V and requires a supply voltage of 5 V. Key electrical specifications include a typical output power of -5.0 ±1 dBm, a phase noise of -118 dBc/Hz, and a second harmonic level of -20 dBc. The maximum current consumption is 40 mA, with a pushing factor of 0.5 MHz/V. It is housed in a 16-QFN package measuring 12.70 mm x 12.70 mm x 5.59 mm and supports an operating temperature range of -40°C to +85°C.

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Crystek Corporation documentation. Ensure that the specific suffix matches the required frequency range and tuning characteristics. Confirm RoHS compliance status through the manufacturer's certificate of conformity. Validate package dimensions and pinout against the latest datasheet to ensure compatibility with existing PCB footprints before finalizing procurement orders.

Selection Notes

Select this model when a fixed center frequency near 410.5 MHz is required with a tuning span of approximately 35 MHz. Consider the 5 V supply requirement and 40 mA current draw for power budgeting. Evaluate the -118 dBc/Hz phase noise specification against system sensitivity requirements. Ensure the 16-QFN footprint fits within the available board area and thermal management constraints for the intended operating environment.
