- Provides stable LVCMOS clock signals for digital circuit synchronization
- Includes hardware enable/disable pin for power management control
- Utilizes a small footprint SMD package for space-constrained designs
Applications
- Precision timing in embedded systems
- Clock generation for microprocessors and FPGAs
- Synchronization in communication modules
Procurement Notes
Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure compatibility with required enable/disable functionality and voltage levels. Confirm that the 1.8V supply requirement aligns with the target system design before procurement. Check for any recent revisions to the 18QHTF21 series specifications.
Selection Notes
Select this component when a 13.4865 MHz reference is required with LVCMOS output compatibility. Ensure the design supports 1.8V operation and has available GPIO pins for the enable/disable control signal. Consider the 2.0x1.6mm package size constraints during PCB layout planning.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized 4-SMD no-lead form factor. Mercury Electronics specializes in quartz-based frequency control products, including crystals, oscillators, and filters, serving global electronics manufacturing needs.
Replacement Considerations
Direct substitutes include other 13.4865 MHz LVCMOS oscillators in 2.0x1.6mm packages with 1.8V operation and enable pins. Verify pinout compatibility and electrical parameters such as load capacitance and drive strength before substitution.
