Procurement Notes
Verify the specific ordering suffix against official Crystek documentation to ensure correct packaging and variant selection. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Check for any additional mechanical or electrical constraints defined in the latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when a fixed QFN footprint is required for space-constrained designs. Ensure the control voltage range matches the system's available tuning voltage, typically 0.5V to 4.5V. Verify that the 10mA maximum current draw fits within the power budget of the 5V supply rail without exceeding thermal dissipation limits.
Part Context
This part belongs to the CVCO55 series of Voltage Controlled Oscillators from Crystek Corporation. The series provides various frequency bands optimized for microwave and radio frequency applications. The BE suffix indicates specific performance characteristics within the broader product line, distinguishing it from other variants like CC or CL series models.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires consulting official manufacturer substitution guides or equivalent technical specifications from alternative suppliers.
