Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency and package specifications. Confirm that the component matches the required LVCMOS logic level and 1.8V supply voltage constraints for your design. Cross-reference the part number with the latest datasheet to validate pinout and electrical characteristics before integration.

Selection Notes

Select this component when a precise 6.498 MHz timing source is required for low-voltage applications. Ensure the design supports the 1.8V operating voltage and accommodates the small 2.0x1.6 mm footprint. Verify that the LVCMOS output swing is compatible with the receiving logic inputs of the target circuit.

Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency-control products, including quartz crystals and oscillators. This component belongs to their series of standard XO devices, designed for reliable timing in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 6.498 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify electrical parameters and pin assignments with alternative manufacturers' datasheets.
