Oscillators Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the enable/disable feature versus standby mode variants. Ensure the 1.8V supply requirement aligns with system design constraints. Confirm package dimensions match PCB footprint specifications before procurement.
Oscillators Selection Notes
Select this component when a 18.4332 MHz reference signal is required with low-voltage operation. The enable/disable pin allows for dynamic power control during idle periods. Consider thermal performance and load capacitance requirements relative to the host circuit design.
Oscillators Part Context
This part belongs to the QHTF series from Mercury Electronic, which offers various hermetic ceramic leadless SMD packages. The series supports frequencies from 1.0 MHz to 200 MHz across different supply voltages. Mercury Electronics is a pioneer in quartz crystal manufacturing with decades of industry experience.
Oscillators Replacement Considerations
The 18QHTF21-18.4332-PD variant offers similar specifications but includes Standby (Power Down) functionality instead of standard Enable/Disable. Verify functional equivalence regarding control logic before substitution.
