Procurement Notes
Verify the specific suffix against official Mercury Electronics documentation to confirm electrical parameters and pinout configuration. Ensure the ordering part number matches the required frequency and voltage specifications. Cross-reference with authorized distributors to validate authenticity and avoid counterfeit components. Confirm RoHS compliance status if environmental regulations apply to the end product.
Selection Notes
Select this component when a precise 95 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 1.8V supply requirement and ensure the design supports the enable/disable control feature for power management. Evaluate the 4-SMD package dimensions against available PCB real estate. Verify temperature stability requirements align with the standard XO characteristics provided in the datasheet.
Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd., a supplier specializing in quartz crystals and oscillators. The series typically offers various frequencies and voltage options within a standardized small footprint. Mercury Electronics has been manufacturing frequency control products since 1973, focusing on reliability and precision timing solutions for global markets.
Replacement Considerations
Direct substitutes may include other 95 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson or SiTime. Verify that replacement parts match the 1.8V supply voltage and enable/disable pin configuration. Check for identical frequency tolerance and load capacitance requirements to ensure circuit compatibility without redesign.
