Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and package types. Confirm that the selected variant matches the intended application's frequency stability and load requirements. Cross-reference official datasheets for pinout configurations and electrical characteristics before integration into design schematics.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 1.8V systems. Ensure the design accommodates the 2.0x1.6mm footprint. Consider the need for power-down functionality if system-level power management is a priority. Verify that the LVCMOS output level aligns with the receiving logic circuitry.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The series offers various frequencies and voltage options within a small form factor. Mercury Electronics has been a supplier of frequency-control products since 1973, focusing on timing solutions for industrial and consumer electronics.

Oscillators Replacement Considerations

Direct substitutes include other 27.6 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify dimensional tolerances and pin assignments before substitution. Alternative parts may require adjustment of decoupling capacitors or layout traces to match electrical performance.
