18QHTF21-16.392658-PD

Oscillators Overview

The 18QHTF21-16.392658-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.392658 MHz with an LVCMOS output logic level. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage power consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby or power-down control capability
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper soldering and electrical connection.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The inclusion of a power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Verify that the operating temperature range meets the environmental conditions of the intended application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The suffix PD indicates the presence of a power-down pin, distinguishing it from models without this control feature.

Oscillators Replacement Considerations

Direct substitutes must match the 16.392658 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify equivalent performance specifications such as frequency stability and phase noise if available.
