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

Applications

• General clock signal generation
• Embedded system timing references
• Consumer electronics circuitry

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with your design requirements. Confirm that the 1.8V supply voltage and LVCMOS output levels match your target circuit specifications before procurement.

Selection Notes

Select this component when a precise 78.3 MHz clock source is required within space-constrained designs. Ensure the host circuit supports the 1.8V operating voltage and can interface correctly with LVCMOS logic levels for reliable signal transmission.

Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series is characterized by small form factors suitable for modern electronic assemblies. The 'PD' suffix typically indicates specific packaging or handling characteristics defined by the manufacturer.

Replacement Considerations

Direct substitutes must match the 78.3 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical parameters with alternative manufacturers before integration.
