Procurement Notes

Verify the specific ordering suffix and package variant against the official Crystek datasheet to ensure compatibility with your design requirements. Confirm that the RoHS3 compliance status meets your environmental regulations. Cross-reference the pinout and thermal characteristics with your PCB layout guidelines before finalizing procurement. Ensure the supplier provides valid documentation matching the manufacturer's part number.

Selection Notes

Select this component when a narrow frequency band around 1660 MHz is required with low phase noise. Consider the 0.5 V to 2.0 V tuning range for control circuit compatibility. Evaluate the -15 dBm output power against system gain requirements. Compare the 35 mA current draw with power budget constraints. Verify that the operating temperature range suits the intended environment.

Part Context

This model belongs to the CVCO55 series by Crystek Corporation, which focuses on voltage-controlled oscillators for RF and microwave frequencies.
