18QHTF21-31.820-OE

Oscillators Overview

The 18QHTF21-31.820-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 31.82 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• LVCMOS output logic interface
• Enable/Disable control functionality
• Compact surface-mount package

Oscillators Applications

• General clock signal generation
• Embedded system timing
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the Enable/Disable pin logic levels are compatible with the controlling microcontroller or FPGA to prevent unintended state changes during operation.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is required for clock generation. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Consider the LVCMOS output compatibility with downstream digital logic families. Verify that the enable/disable feature meets power efficiency requirements for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer specializing in quartz crystals and oscillators. The series typically includes various frequencies and voltage options within a standardized small outline no-lead package format designed for high-volume surface mount assembly processes.

Oscillators Replacement Considerations

Direct substitutes include other 31.82 MHz LVCMOS oscillators in 4-SMD No Lead packages with 1.8V operation and enable/disable pins. Verify pinout compatibility and electrical specifications such as jitter and phase noise if critical. Cross-reference with similar offerings from other manufacturers ensuring identical package dimensions.
