Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm lead-free compliance and RoHS status. Ensure the operating temperature range meets the environmental requirements of the target application. Confirm that the 1.8V supply voltage aligns with the system power rails before integration.

Oscillators Selection Notes

Select this component when a 14.476 MHz clock source is required with LVCMOS outputs. The 1.8V supply requirement dictates compatibility with low-voltage logic families. The enable feature is critical for systems requiring power saving modes. Verify footprint compatibility with the 2.0x1.6mm SMD package during PCB layout design.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a Taiwanese manufacturer specializing in quartz crystals and oscillators. The series includes various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or compliance variations within the product line. Mercury has been a pioneer in the Taiwan crystal industry since 1973.

Oscillators Replacement Considerations

Direct substitutes include other 14.476 MHz LVCMOS oscillators in 2.0x1.6mm packages from manufacturers like Epson or NDK. Cross-reference electrical parameters such as load capacitance and drive level. Verify pinout compatibility if replacing with different brands.
