18QHTF21-58.9248-PD

Overview

The 18QHTF21-58.9248-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 58.9248 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a power-down feature for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output interface
• Includes power-down functionality
• Compact surface-mount design

Applications

• Precision timing applications
• Electronic devices requiring stable clock signals

Procurement Notes

Verify the specific ordering suffix to confirm the package type and shipping configuration. Ensure the required frequency tolerance and load capacitance match the target circuit design. Confirm that the 1.8V supply voltage aligns with the system power rails before finalizing procurement.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small footprint. The 2.0x1.6 mm package size suits space-constrained layouts. Consider the power-down capability if energy efficiency during idle states is a priority for the application.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within a consistent 4-SMD form factor. The PD suffix typically indicates the inclusion of a power-down pin or function for standby management.

Replacement Considerations

Check for direct substitutes within the same series offering identical 58.9248 MHz frequency and 1.8V operation. Verify pin compatibility and package dimensions to ensure mechanical interchangeability without redesigning the PCB layout.
