18QHTF21-13.980-PD

Overview

The 18QHTF21-13.980-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.98 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down capability. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Features integrated power-down functionality for energy management
• Provides LVCMOS output signal compatibility

Applications

• General clock generation for digital circuits
• Embedded systems requiring precise timing references
• Portable electronics utilizing low-power components

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply rail is stable to maintain oscillator performance. Confirm that the PCB layout accommodates the 4-SMD no-lead footprint dimensions accurately to ensure proper soldering and electrical connection.

Selection Notes

Select this component when a 13.98 MHz reference is required alongside low power consumption constraints. The LVCMOS interface ensures compatibility with standard logic families. Consider the physical size of the 2.0x1.6mm package if space is limited within the target application board.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage levels, all sharing a common small form factor. This specific model provides a fixed frequency option within that lineup.

Replacement Considerations

Check for direct substitutes within the same series offering identical frequency and voltage specifications. Verify pinout compatibility and package dimensions to ensure mechanical interchangeability without redesigning the host board.
