18QHTF21-57.710333-PD

Overview

The 18QHTF21-57.710333-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a nominal frequency of 57.710333 MHz with an LVCMOS output signal type. The device requires a 1.8V supply voltage and features a power-down standby function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down standby capability
• Utilizes standard LVCMOS output interface

Applications

• Precision frequency generation systems
• Embedded digital circuits requiring stable clock sources
• Compact electronic devices with space constraints

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper soldering and electrical connection.

Selection Notes

Select this component when a precise 57.710333 MHz clock signal is required in a minimal footprint. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Consider the power-down feature if energy efficiency during idle states is a critical design parameter for the target application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized 4-SMD no-lead package. These components are designed to provide reliable clock signals for high-speed digital applications while maintaining a small physical profile.

Replacement Considerations

Direct substitutes must match the 57.710333 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pin compatibility and electrical specifications with alternative manufacturers before integration.
