Oscillators Procurement Notes

Verify the exact specifications against the official product datasheet from Mercury Electronic Ind. Co., Ltd. before procurement. Ensure compatibility with the required 1.8V supply and LVCMOS logic levels. Confirm the 4-SMD, No Lead package dimensions match the design layout. Check for any specific ordering suffix requirements or variations.

Oscillators Selection Notes

Select this component when a 16.66 MHz clock source with LVCMOS output is required. Consider the 1.8V operating voltage and standby feature for power-sensitive designs. Verify the 4-SMD, No Lead package fits the PCB constraints. Compare against other frequencies in the 18QHTF21 series if different timing is needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies with consistent LVCMOS output and 1.8V operation. Mercury Electronics has a history of manufacturing quartz crystals since 1973, positioning itself as a pioneer in the Taiwan crystal industry.

Oscillators Replacement Considerations

Other parts in the 18QHTF21 series with different frequencies may serve as alternatives if timing requirements change. Direct substitutes must maintain the 1.8V supply, LVCMOS output, and 4-SMD, No Lead package form factor. Consult the manufacturer's documentation for cross-reference information.
