Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications 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.

Oscillators Selection Notes

Select this component when a precise 26.598 MHz clock source is required in a minimal space-constrained environment. The choice is driven by the need for low-power consumption via the standby feature and compatibility with standard LVCMOS logic levels. Consider the 1.8V operating voltage as a primary constraint for power supply design integration.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in quartz crystals and oscillators. The series typically offers various frequencies within a small SMD form factor. This specific model provides a fixed frequency solution for applications requiring stable timing without the complexity of programmable devices.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinouts and electrical characteristics but different frequencies, such as 18QHTF21-25.000-PD or 18QHTF21-27.000-PD, if frequency adjustment is permissible. Cross-brand replacements must match the 4-SMD no-lead package, 1.8V supply, and LVCMOS output type.
