• Includes standby capability for power management
• Utilizes LVCMOS output interface

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the complete part number including the -PD suffix to ensure correct packaging and specifications. Confirm that the 1.8V supply requirement aligns with your system design. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 4-SMD footprint matches your PCB layout constraints before ordering.

Oscillators Selection Notes

Select this component when a precise 54.077 MHz reference is needed with low power consumption. The LVCMOS output is compatible with standard digital logic families. Consider the operating temperature range and load capacitance requirements against your specific application environment. The small form factor aids in space-constrained designs.

Oscillators Part Context

This oscillator belongs to the H21 series of SMD oscillators from Mercury Electronics. The series typically offers standard frequency options with fixed output logic levels. The 18QHTF21 designation indicates the specific pinout and mechanical dimensions associated with this family of products.

Oscillators Replacement Considerations

Direct substitutes must match the 54.077 MHz frequency, 1.8V supply, and LVCMOS output. Verify pin compatibility for the 4-SMD package. Cross-reference with other Mercury Electronics models in the H21 series for potential equivalents.
