Procurement Notes
Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a 100 MHz clock signal is required with low power consumption constraints. The LVCMOS output is suitable for standard digital logic families. Consider the enable pin feature if dynamic power saving is necessary. The small form factor makes it ideal for space-constrained designs compared to larger oscillator packages.
Part Context
This part belongs to the 18QHTF21 series of low-voltage crystal oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and package dimensions. It is designed as a drop-in replacement for higher voltage oscillators where power reduction is prioritized without sacrificing signal integrity or stability.
Replacement Considerations
Direct substitutes include other 100 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Verify pinout compatibility and voltage levels when cross-referencing. Alternative parts may require adjustments to enable logic polarity or load capacitance values.
