Procurement Notes
Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct configuration. Confirm that the OE suffix aligns with the required enable/disable functionality and output specifications. Cross-reference the part number with authorized distributors to validate authenticity and availability before finalizing procurement orders.
Selection Notes
Select this component when a 114.285 MHz clock source is required with LVCMOS compatibility. Ensure the design supports a 1.8V supply rail. Consider the 2.0x1.6mm footprint for PCB layout constraints. Verify that the enable/disable feature meets power management requirements compared to continuous oscillation alternatives.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The 114.285 MHz variant provides a specific timing solution for high-speed digital interfaces or communication protocols requiring this exact frequency reference.
Replacement Considerations
Direct substitutes include other 114.285 MHz XO components with identical 1.8V LVCMOS specifications and 4-SMD 2.0x1.6mm footprints. Verify pinout compatibility and electrical parameters such as load capacitance and drive level before substitution.
