Procurement Notes
Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Request official datasheets to validate electrical parameters for final integration.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The integrated enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor of the 4-SMD package for space-constrained layouts. Verify frequency stability needs against standard XO specifications.
Part Context
Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency-control products, including quartz crystals and oscillators. The company has decades of experience in the industry, producing components for various electronic applications. This model belongs to their standard crystal oscillator lineup, offering reliable timing solutions.
Replacement Considerations
Direct substitutes must match the 10.18 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check pinout compatibility and electrical characteristics carefully. Cross-reference with other manufacturers' equivalent series if availability is an issue, ensuring all functional parameters remain identical.
