CVCO45CL-0100-0140

Overview

The CVCO45CL-0100-0140 is a voltage-controlled oscillator from Crystek Corporation with a frequency range of 100 to 140 MHz and a center frequency of 120 MHz. It operates on a supply voltage of 3.15 V to 5 V, drawing a maximum current of 40 mA. The output power is typically -3 ±3 dBm. Key performance metrics include a typical second harmonic level of -15 dBc and a tuning sensitivity of 10 MHz/V. The device is housed in a compact SMD package measuring 0.4 x 0.49 inches.

Feature Summary

• Voltage-controlled operation within a 100–140 MHz frequency band
• Integrated design for stable RF signal generation
• Compact surface-mount form factor for space-constrained layouts

Applications

• RF communication systems requiring tunable local oscillators
• Frequency synthesis circuits
• Test and measurement instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and electrical characteristics. Confirm that the supply voltage requirements align with your system design before procurement. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure proper handling procedures are followed for the surface-mount package during assembly.

Selection Notes

Select this component when a fixed-frequency crystal is insufficient and electronic tuning across the 100–140 MHz range is required. Consider the -3 dBm output power level to determine if additional amplification stages are necessary for your application. Evaluate the tuning sensitivity of 10 MHz/V against your control voltage resolution needs. Compare the physical dimensions against available PCB real estate constraints.

Part Context

This part belongs to the CVCO45 series of voltage-controlled oscillators manufactured by Crystek Corporation. The series provides various frequency options within the VHF/UHF spectrum. The CVCO45CL-0100-0140 specifically targets the 100–140 MHz band, offering a middle-ground solution between lower and higher frequency variants in the product line.

Replacement Considerations

Consult the official Crystek CVCO selector guide for direct replacements within the same series. Verify that any substitute part matches the 100–140 MHz frequency range and compatible supply voltage specifications. Cross-reference pinouts and thermal requirements to ensure mechanical compatibility.
