• Integrated enable/disable control functionality
• Compact 4-SMD no lead surface-mount package design

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your application's datasheet specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor for space-constrained designs. Verify thermal performance within the specified operating temperature range for reliable long-term operation in your target environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS output and 1.8V operation. The 'OE' suffix typically denotes specific packaging or testing options as defined by the manufacturer's catalog standards for this product line.

Oscillators Replacement Considerations

Direct substitutes must match the 27.45 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package dimensions. Verify pinout compatibility and electrical characteristics such as jitter and phase noise if critical to the application.
