18QHTF21-31.200-PD

Oscillators Overview

The 18QHTF21-31.200-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 31.2 MHz and utilizes LVCMOS output logic levels. The component requires a 1.8V supply voltage and features a standby or power-down function for energy management. 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 logic compatibility
• Integrated standby and power-down functionality
• Low-voltage operation at 1.8V

Oscillators Applications

• General-purpose clock signal generation
• Digital circuit timing synchronization
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications 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 to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-power, 1.8V compatible clock source is required. The LVCMOS interface ensures direct connectivity with standard digital logic families without additional level shifting. Consider the standby feature if power efficiency is critical. Verify that the 31.2 MHz frequency meets the exact timing needs of the target application compared to other available frequencies in the series.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series includes various oscillators such as TCXOs and VCTCXOs. This specific model represents a standard XO variant, distinct from temperature-compensated versions, offering basic timing stability within a small surface-mount form factor for cost-sensitive designs.

Oscillators Replacement Considerations

Direct substitutes include other 31.2 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation from Mercury Electronics, such as the 18QHTF21-51.200-PD or 18QHTF21-6.312-PD, provided the frequency difference is acceptable. Cross-brand replacements require matching voltage, output type, and package dimensions.
