Procurement Notes
Verify the specific part number suffix against official Z-Communications documentation to ensure correct pinout and electrical specifications. Confirm that the procurement channel provides genuine components with traceable manufacturing data. Check for any updated application notes regarding mounting or grounding requirements prior to integration into final assemblies.
Selection Notes
Select this component when a stable 1000 MHz reference is required in a surface mount design. Consider the +3 dBm output power and -5 dBc harmonic suppression for signal integrity needs. Evaluate the 18 MHz/V tuning sensitivity against system loop bandwidth requirements. Ensure the operating temperature range aligns with the environmental conditions of the target application.
Part Context
Z-Communications specializes in RF and microwave signal sources, including voltage-controlled oscillators and phase-locked loops. The CRO series represents their surface mount offerings designed for high performance in wireless applications. This model fits within their portfolio of dielectric resonator-based oscillators engineered for low phase noise and wide tuning ranges.
Replacement Considerations
Consult official manufacturer substitution lists for direct equivalents. Verify that any alternative maintains the 1000 MHz center frequency and compatible supply voltage parameters.
