18QHTF21-39.200-PD

Oscillators Overview

The 18QHTF21-39.200-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 39.2 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to reduce energy consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range suitable for general electronic applications.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Includes standby mode functionality to enable power-down capabilities
• Utilizes a leadless surface-mount package for space-constrained designs

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference sources for microcontrollers and processors
• Data communication interfaces requiring stable frequency standards

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 39.2 MHz timing source. The LVCMOS output is suitable for direct interfacing with standard logic families without additional level shifting. Consider the power-down feature if energy efficiency is a priority in battery-operated or portable devices. Verify that the operating temperature range meets the environmental conditions of the intended application.

Oscillators Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics, which are known for providing stable timing solutions in a small form factor. The series typically offers various frequencies and voltage options to suit different electronic design needs. Mercury Electronics has been a supplier of frequency control products since 1973, focusing on quartz crystals and oscillators.

Oscillators Replacement Considerations

Direct substitutes may include other 39.2 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package with 1.8V operation. Verify pinout compatibility and electrical specifications such as phase noise and jitter before substitution. Cross-reference with similar models from Mercury Electronics or other manufacturers offering equivalent timing performance.
