Applications
- High-performance embedded systems requiring precise timing
- Communication equipment utilizing standard clock interfaces
- Consumer electronics with space-constrained PCB layouts
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your board layout to prevent soldering issues during assembly.
Selection Notes
Select this component when a low-voltage LVCMOS output is required for high-frequency applications. Consider the enable/disable feature if power conservation is critical. Verify that the operating temperature range meets your environmental specifications. Compare package dimensions against available board space to ensure compatibility.
Part Context
This oscillator belongs to the QHTF series from Mercury Electronics, which specializes in frequency control products. The company has a long history in quartz crystal manufacturing. This specific model represents a standard XO solution suitable for general-purpose timing needs in modern electronic devices.
Replacement Considerations
Direct substitutes must match the 93.33 MHz frequency, 1.8V supply, and LVCMOS output. Check pinout compatibility for the 4-SMD no-lead package. Verify equivalent electrical parameters such as phase noise and stability before swapping components.
