Procurement Notes
Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm exact electrical tolerances and pinout configuration. Ensure the 1.8V supply requirement aligns with system design constraints before procurement. Cross-reference the 4-SMD package dimensions with PCB footprint libraries to guarantee mechanical fitment during assembly.
Selection Notes
Select this component when a precise 69.102 MHz reference is required for LVCMOS-compatible circuits. The integrated enable feature allows for power management optimization. Consider the small form factor for space-constrained designs. Verify that the operating temperature range meets the environmental requirements of the target application zone.
Part Context
This part belongs to the Mercury Electronics SMD oscillator series, designed for high-frequency stability. The manufacturer specializes in quartz-based timing solutions including crystals, TCXOs, and VCTCXOs. This specific model represents a standard XO variant optimized for low-power digital applications requiring precise clock signals.
Replacement Considerations
The 18QHTF21-69.102-PD is a documented alternative from the same manufacturer offering identical frequency and package specifications. Verify if the PD suffix denotes any functional differences or updated manufacturing revisions compared to the OE variant.
