- General electronic timing circuits
- Digital signal processing systems
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a precise 91.955 MHz clock signal is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Consider the power-down feature if energy conservation is critical for the application's operational profile.
Part Context
This part belongs to the Mercury Electronic SMD oscillator series designed for high-frequency timing applications. The manufacturer specializes in quartz-based frequency control products, including crystals and oscillators. This specific model represents a standard XO variant optimized for compact surface-mount integration in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include other 91.955 MHz LVCMOS oscillators from Mercury such as the 18QHTF21-91.955 without the PD suffix if power-down is not needed. Cross-reference pinout compatibility and ensure identical supply voltage and package dimensions are maintained for seamless replacement.
