- Embedded electronics applications
Procurement Notes
Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the exact output logic and enable pin configuration. Ensure the 1.8V supply requirement aligns with the target circuit design before procurement. Cross-reference the 4-SMD no-lead package dimensions with PCB footprint specifications to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when a 108.0 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint relative to the system power rails. Evaluate the small 2.0x1.6mm package size against available board space. Confirm that the enable/disable feature meets system power management requirements compared to always-on alternatives.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The series typically offers various frequencies and packages. Mercury Electronics has a long history in frequency control products, positioning this oscillator within their standard XO lineup for general-purpose timing applications.
Replacement Considerations
Check the datasheet for the 18QHTF21-108.000-PD variant, which shares the same frequency and package but may differ in suffix specifications. Verify electrical parameters and pinout compatibility before substituting any other model from the manufacturer's catalog.
