18QHTF21-92.500-PD

Overview

The 18QHTF21-92.500-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 92.5 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and an integrated standby or power-down function to minimize energy consumption when inactive. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• Integrates LVCMOS output interface for direct digital logic compatibility
• Supports standby mode with power-down capability for energy efficiency
• Utilizes a lead-free 4-SMD surface-mount package design

Applications

• Battery-powered portable electronic devices requiring low current draw
• Digital signal processing circuits needing precise clock timing
• Communication modules utilizing standard LVCMOS interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for detailed electrical characteristics and reliability data prior to final procurement decisions.

Selection Notes

Select this model when a 92.5 MHz clock source is required with LVCMOS signaling. Consider the 1.8V operating voltage for compatibility with modern low-voltage logic families. The power-down feature makes it suitable for systems with strict power management needs. Evaluate the 4-SMD package size against available board space. Compare performance metrics such as phase noise and stability if high-frequency precision is critical for the application.

Part Context

Mercury Electronics Ind. Co., Ltd. has been manufacturing frequency control products since 1973, establishing itself as a pioneer in the quartz crystal industry in Taiwan. The company specializes in producing various oscillators and resonators for diverse electronic applications. This part belongs to their series of standard crystal oscillators designed for general-purpose timing needs.

Replacement Considerations

The 3QHTF21-92.500-PD is listed as a related variant; however, it typically operates at 3.3V rather than 1.8V. Verify voltage compatibility carefully before substitution. Other models in the 18QHTF21 series may offer different frequencies but share similar packaging and logic types.
