18QHTF21-57.750333-OE

Overview

The 18QHTF21-57.750333-OE is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 57.750333 MHz. It utilizes LVCMOS output logic and functions with a 1.8V supply voltage. The component features an Enable/Disable control pin for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes Enable/Disable functionality for power optimization
• Compact 4-SMD surface-mount package design

Applications

• Precision timing applications in electronic devices
• General clock signal generation
• Embedded systems requiring stable frequency references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics to validate electrical characteristics and reliability standards for your specific application environment.

Selection Notes

Select this model when a precise 57.750333 MHz clock source is required in a low-profile surface-mount form factor. The LVCMOS output is suitable for direct connection to most digital logic families without additional buffering. Consider the Enable/Disable feature if dynamic power management is a priority. Verify compatibility with 1.8V operation across the specified temperature range.

Part Context

This component belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6mm package. These oscillators are designed for high stability and are commonly used in consumer electronics, communications equipment, and industrial control systems where space-saving and reliable timing are essential.

Replacement Considerations

Direct substitutes include other 57.750333 MHz LVCMOS oscillators in the same 4-SMD package, such as the 18QHTF21-57.750333 (without OE suffix) if enable functionality is not critical. Cross-reference with similar models from Mercury or other manufacturers ensuring identical voltage, output type, and footprint.
