18QHTF21-14.240-PD

Oscillators Overview

The 18QHTF21-14.240-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 14.24 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.00mm x 1.60mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features a standby mode to reduce power consumption during idle periods
• Utilizes a surface-mount 4-SMD no-lead package for automated assembly

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 14.24 MHz
• Embedded devices utilizing low-voltage 1.8V power domains

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the PCB footprint matches the 2.00mm x 1.60mm 4-SMD no-lead package specifications to guarantee proper mechanical fit and electrical connection.

Oscillators Selection Notes

Select this component when a precise 14.24 MHz timing source is required within a constrained physical space. The choice is appropriate for designs prioritizing low power consumption through the available standby feature. Consider the LVCMOS output level compatibility with downstream logic gates. The small form factor makes it suitable for high-density board layouts where larger packages cannot be accommodated.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options within a standardized 2.0x1.6mm footprint. Mercury Electronic has established itself as a manufacturer of quartz crystals and frequency control products since 1973, providing these components for industrial and consumer electronics applications.

Oscillators Replacement Considerations

Direct substitutes must match the 14.24 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar miniature XO packages if Mercury Electronics inventory is unavailable.
