Oscillators Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct voltage and output configuration. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any specific environmental ratings or tolerance levels defined in the manufacturer's datasheet before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 27.145 MHz clock source is required with low voltage operation. Ensure the application supports LVCMOS logic levels and can accommodate the 1.8V supply rail. Consider the physical footprint constraints as the device uses a small 4-SMD package. Validate that the enable pin functionality meets the system's power management strategy.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics XO series, which provides standard frequency solutions. The brand has a history of manufacturing quartz-based frequency control products. The model number indicates specific electrical parameters including frequency and voltage, distinguishing it from other variants in the product line with different frequencies or packaging options.

Oscillators Replacement Considerations

Direct substitutes must match the 27.145 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Consult official cross-reference lists from Mercury Electronics for validated alternative part numbers.
