18QHTF21-13.333333-PD

Overview

The 18QHTF21-13.333333-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.333333 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports low-power standby operation via power-down control
• Delivers standard LVCMOS output signal levels
• Utilizes a leadless surface-mount package design

Applications

• General clock generation for digital circuits
• Timing reference for communication interfaces
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required supply voltages and output types. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly before procurement.

Selection Notes

Select this component when a stable 13.333333 MHz reference is required with low voltage operation. Consider the LVCMOS interface compatibility with downstream logic families. Evaluate the need for power-down capabilities to manage system energy consumption during idle states compared to continuous operation alternatives.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same form factor. The series provides standardized XO solutions for consumer and industrial electronics. Mercury Electronics leverages decades of quartz crystal manufacturing expertise to produce these timing components.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinouts but different frequencies, such as 18QHTF21-51.200-PD or 18QHTF21-96.768-PD, provided the frequency requirement changes. Cross-brand replacements require matching LVCMOS output, 1.8V supply, and 4-SMD no-lead package specifications.
