18QHTF21-57.3347-PD

Overview

The 18QHTF21-57.3347-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 57.3347 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) function to manage power consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode functionality for power management
• Utilizes a surface-mount package design for automated assembly

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix against official documentation to ensure correct operational modes. Confirm that the PD suffix corresponds to the intended standby functionality. Cross-reference the frequency tolerance and load capacitance requirements with the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V supply is required alongside precise frequency stability. Ensure the application supports LVCMOS logic levels and can accommodate the specified package footprint. Consider the standby feature if power efficiency during idle periods is a critical design parameter.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan's quartz industry, providing reliable oscillators for various electronic applications requiring stable clock signals.

Replacement Considerations

Direct substitutes must match the 57.3347 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm SMD package. Verify pinout compatibility and electrical specifications with alternative manufacturers before implementation.
