- Integrated enable/disable control functionality
- Compact 4-SMD no-lead surface mount package design
Applications
- Digital signal processing systems
- Communication equipment timing circuits
- Embedded system clock generation
Procurement Notes
Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the 1.8V supply voltage requirement aligns with the target system's power rails before procurement. Ensure the LVCMOS output swing is compatible with downstream logic levels.
Selection Notes
Select this component when a fixed 82.944 MHz frequency is required with low-voltage operation. The enable pin allows for dynamic power control in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained PCB layouts compared to larger through-hole alternatives.
Part Context
This part belongs to the Mercury Electronics 18QHTF series of standard oscillators. The series offers various frequencies and voltage options within a consistent 4-SMD footprint. The 'OE' suffix typically denotes specific packaging or testing standards defined by the manufacturer for this product line.
Replacement Considerations
Direct substitutes must match the 82.944 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify electrical parameters such as load capacitance and phase noise if critical. Cross-reference with other manufacturers offering equivalent SMD oscillators.
