18QHTF21-16.386-PD

Oscillators Overview

The 18QHTF21-16.386-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 16.386 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down (standby) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for applications requiring precise timing signals in low-voltage digital systems.

Oscillators Feature Summary

• Supports LVCMOS output logic for direct interface with digital circuits
• Includes standby mode capability via power-down control
• Utilizes a leadless surface-mount package for space-constrained designs

Oscillators Applications

• Portable electronic devices requiring low-power timing sources
• Digital communication interfaces needing stable clock signals
• Embedded systems utilizing 1.8V logic families

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD no-lead package dimensions to guarantee proper assembly and electrical connection.

Oscillators Selection Notes

Select this oscillator when a 16.386 MHz clock signal is required within a 1.8V logic environment. Consider the power-down feature if battery life or thermal management is critical. Compare package size constraints against alternative oscillators to ensure compatibility with the target PCB layout and manufacturing processes.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor XO solutions. The series typically offers various frequencies optimized for consumer electronics and industrial applications. The 'PD' suffix indicates the inclusion of a power-down pin functionality, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes may include other 16.386 MHz LVCMOS oscillators in 2.0x1.6mm packages from manufacturers like Epson or SiTime. Verify pinout compatibility and voltage levels carefully. Cross-reference datasheets for equivalent jitter performance and temperature stability ranges to ensure functional parity.
