Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the 4-SMD package footprint matches the PCB layout constraints. Cross-reference the OE suffix to ensure correct enable functionality availability.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small 2.0x1.6 mm footprint for space-constrained applications. Verify that the 26.65 MHz frequency meets the system clock requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The -OE suffix typically denotes the enable/disable capability. These components are designed for general-purpose timing applications in modern electronic systems.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with different frequencies but identical package and electrical characteristics, such as the 18QHTF21-50.2267-OE or 18QHTF21-21.200-OE, provided the frequency difference is acceptable for the application.
