Oscillators Procurement Notes

Verify the specific voltage tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable to ensure proper oscillator startup. Ensure PCB footprint matches the 2.0x1.6 mm SMD package dimensions to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside an active enable control feature. The small 2.0x1.6 mm form factor makes it suitable for space-constrained designs. Consider the LVCMOS output compatibility with downstream logic levels to prevent signal integrity issues in high-speed digital circuits.

Oscillators Part Context

This part belongs to Mercury's QuikXO series, which focuses on fast-delivery CMOS output clock solutions. The manufacturer has produced frequency control products since 1973, establishing expertise in Taiwan's crystal industry. This series typically offers standardized frequencies with reliable performance for general-purpose electronic applications.

Oscillators Replacement Considerations

Direct substitutes include other 20.736 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and voltage levels when cross-referencing. Ensure the replacement also supports the enable/disable functionality if power management is critical to the design.
