18QHTF21-57.600-PD

Overview

The 18QHTF21-57.600-PD is a 57.6 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a supply voltage of 1.8V and features LVCMOS output logic. The component utilizes a 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. Key functional specifications include support for Standby (Power Down) mode and an OE (Output Enable) pin. The device is designed for standard clock signal generation applications requiring low power consumption and compact form factors.

Feature Summary

• Supports Standby (Power Down) mode for energy efficiency
• Integrates Output Enable (OE) control functionality
• Utilizes LVCMOS output logic for digital interface compatibility

Applications

• General purpose clock signal generation in embedded systems
• Timing reference sources for portable electronic devices
• Clock distribution in compact consumer electronics

Procurement Notes

Verify the specific suffix 'PD' against official Mercury Electronics documentation to confirm Power Down capability and package type. Ensure the 1.8V supply voltage requirement aligns with system design constraints. Cross-reference the 4-SMD No Lead footprint with PCB layout guidelines to guarantee mechanical fit and soldering reliability during assembly processes.

Selection Notes

Select this component when a 57.6 MHz frequency is required with strict space limitations due to its 2.0x1.6 mm footprint. Consider the 1.8V operating voltage for compatibility with low-voltage digital logic families. Evaluate the need for standby power management and output enable controls to determine if this specific variant meets system power and control requirements compared to non-configurable alternatives.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard clock oscillators in various frequencies and packages. The 18QHTF21 designation indicates a specific size and performance class within their portfolio. The '-PD' suffix typically denotes specific electrical or mechanical characteristics such as Power Down functionality, distinguishing it from standard variants like the '-OE' or generic versions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with direct replacements only through official manufacturer cross-reference lists or datasheet equivalence tables. Do not assume functional interchangeability based on frequency and package alone without verifying electrical parameters and pin configurations.
