Procurement Notes
Verify the specific ordering suffix against official Mercury Electronics documentation to confirm exact electrical parameters and package variations. Ensure compatibility with target system voltage levels and load requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a stable 119.466 MHz reference is required in low-voltage environments. Consider the enable feature for power-sensitive designs. Evaluate thermal performance and size constraints relative to the 4-SMD footprint. Confirm that LVCMOS logic levels match downstream receiver inputs.
Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series offers various frequencies and packages tailored for modern electronic devices. Mercury Electronics has decades of experience in Taiwan's crystal manufacturing industry.
Replacement Considerations
Check for direct substitutes within the same series offering identical frequency and package dimensions. Verify that alternative parts support the same 1.8V operation and LVCMOS outputs. Ensure any replacement maintains compatible enable/disable functionality.
