18QHTF21-58.980-PD

Overview

The 18QHTF21-58.980-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 58.98 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 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down capability for energy management
• Utilizes LVCMOS output interface

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet to ensure reliable oscillator performance.

Selection Notes

Select this component when a precise 58.98 MHz reference is required in space-constrained designs. The choice depends on the compatibility of the LVCMOS output with the receiving digital logic and the availability of a regulated 1.8V power source for the oscillator core.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies in a small 2.0x1.6mm footprint, providing a standardized solution for high-density PCB layouts requiring reliable clock sources.

Replacement Considerations

Direct substitutes must match the 58.98 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and thermal characteristics before swapping.
