• Consumer electronics circuit boards

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Oscillators Selection Notes

Select this component when a low-profile 2.0x1.6mm oscillator is required for 1.8V logic systems. Consider the enable pin feature if dynamic power saving is necessary. Verify that the standard frequency stability meets your application's jitter and accuracy needs compared to higher-grade alternatives.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small form factor oscillators. The series typically offers various frequencies within a single package type. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though exact details require datasheet confirmation.

Oscillators Replacement Considerations

Direct substitutes include other 27.2MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Epson, NDK, or SiTime. Ensure voltage compatibility (1.8V) and pinout alignment. Check if the replacement supports the same enable/disable control scheme.
