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 package footprint matches your PCB layout guidelines to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator with enable functionality is required. Consider the 18.75 MHz frequency suitability for your data transmission or processing rates. Evaluate the thermal performance and stability needs relative to the standard XO classification to ensure it meets the environmental operating conditions of your final product application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor oscillators. The series typically offers various frequencies within a 2.0x1.6 mm package. The '-OE' suffix likely denotes specific ordering or packaging variations, though exact details require datasheet confirmation. This model represents a standard solution for compact timing needs.

Oscillators Replacement Considerations

Direct substitutes must match the 18.75 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical. Cross-reference with other manufacturers offering similar small-footprint XO components with enable pins.
