Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform'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.

Oscillators Selection Notes

Select this component when a precise 2.176 MHz clock signal is required within a low-power environment. The LVCMOS interface ensures compatibility with standard logic families operating at 1.8V. Consider the integrated power-down feature if system efficiency is critical. The small form factor makes it suitable for space-constrained designs where larger oscillators cannot fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series offers various frequencies and voltages, typically featuring SMD packages. Mercury has been a pioneer in the Taiwan crystal industry since 1973, providing reliable timing solutions for global electronics manufacturing.

Oscillators Replacement Considerations

Direct substitutes must match the 2.176 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators with identical electrical specifications to ensure functional equivalence.
