18QHTF21-114.215-PD

Overview

The 18QHTF21-114.215-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 114.215 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Provides standard LVCMOS output signals

Applications

• General clock generation for digital circuits
• Embedded systems requiring precise timing
• Communication modules utilizing standard logic interfaces

Procurement Notes

Verify the specific frequency suffix (114.215) to ensure compatibility with target circuit requirements. Confirm that the 1.8V supply voltage aligns with the system design. Check the package type (4-SMD, No Lead) against PCB footprint specifications. Ensure the manufacturer designation matches Mercury Electronics Ind. Co. Ltd to avoid counterfeit components.

Selection Notes

Select this component when a 114.215 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint during power budgeting. Evaluate the small form factor (2.0x1.6mm) for space-constrained designs. Verify thermal performance within the specified operating temperature range for the intended application environment.

Part Context

This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options in similar compact packages. The 'PD' suffix indicates the inclusion of a power-down pin or feature, distinguishing it from basic continuous-operation variants within the same family.

Replacement Considerations

Direct substitutes must match the 114.215 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Cross-reference with other manufacturers offering identical electrical and mechanical specifications to ensure pinout and timing compatibility.
