18QHTF21-34.000-OE

Oscillators Overview

The 18QHTF21-34.000-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 34 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital signal compatibility
• Features an enable/disable pin for power management control
• Utilizes a surface-mount package design for automated assembly

Oscillators Applications

• General clock generation for embedded systems
• Timing reference for communication interfaces
• Power-sensitive portable electronic devices

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target circuit design. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the enable/disable pin logic levels are compatible with the controlling microcontroller or FPGA to prevent unintended oscillation states during operation.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is required alongside precise timing accuracy. The small 2.0x1.6mm footprint makes it suitable for space-constrained PCB layouts. Consider the enable/disable feature if power conservation is critical for the application's standby modes compared to always-on oscillator alternatives.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series typically offers various frequencies and voltage options within similar physical footprints. Mercury has been a supplier of timing components since 1973, focusing on crystals and oscillators for industrial and consumer electronics markets.

Oscillators Replacement Considerations

Check the 18QHTF21-34.000-PD variant for potential pinout or packaging differences. Verify electrical compatibility with other 34MHz LVCMOS oscillators in the same package size before substitution.
