CVCO55CL-0260-0285

Overview

The CVCO55CL-0260-0285 is a Voltage Controlled Oscillator (VCO) from the Crystek CVCO55 series, manufactured by Crystek Corporation. It operates within a frequency range of 260 MHz to 285 MHz, with a center frequency of 272.5 MHz. The device requires a supply voltage of 7 V and accepts a tuning voltage between 0.5 V and 6.5 V. It features a load capacitance of 150 pF and is housed in a surface-mount package measuring 12.70 mm x 12.70 mm. The component is RoHS compliant and designed for operation across a temperature range of -40°C to 85°C.

Feature Summary

• Provides a tunable frequency output within the 260 MHz to 285 MHz band
• Utilizes a compact 12.70 mm square surface-mount footprint
• Operates with a standard 7 V supply and wide tuning voltage range
• Maintains performance stability across industrial temperature extremes

Applications

• RF signal generation in communication systems
• Frequency synthesis modules
• Test and measurement equipment oscillators

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm that the 7 V supply requirement aligns with your power budget, as this differs from other variants in the series. Check RoHS compliance documentation if environmental regulations apply to your final product assembly. Ensure proper thermal management considerations are integrated into the PCB layout for the specified operating temperature range.

Selection Notes

Select this model when a fixed-frequency oscillator is insufficient and a tunable range around 272.5 MHz is required. Compare the 7 V supply requirement against available board voltages; if only 5 V is available, consider alternative Crystek models like the CVCO55CC series. Evaluate the 150 pF load capacitance against your circuit's impedance matching needs. Verify that the physical dimensions fit within the allocated space on the printed circuit board.

Part Context

This component belongs to the CVCO55 family of voltage-controlled oscillators from Crystek Corporation. The series offers various frequency ranges and supply voltage configurations. The CVCO55CL variant specifically denotes the 7 V supply version, distinguishing it from lower-voltage counterparts. This part number represents a specific frequency subset within the broader CVCO55 lineup, tailored for applications requiring precise frequency agility in the VHF band.

Replacement Considerations

Direct substitutes must match the 260-285 MHz range, 7 V supply, and 12.70mm footprint. Cross-reference with Crystek CVCO55CL models having similar frequency codes. Verify pinout compatibility before substitution. No direct cross-brand replacements are confirmed without detailed electrical equivalence analysis.
