18QHTF21-60.003-PD

Overview

The 18QHTF21-60.003-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 60.003 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption efficiently. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component serves as a precise clock source for digital circuits requiring low-profile surface-mount integration.

Feature Summary

• Integrates LVCMOS output logic for direct interface with digital loads
• Features a dedicated standby mode to reduce power consumption during idle periods
• Utilizes a leadless SMD package design for automated surface-mount assembly processes

Applications

• Portable electronic devices requiring low-power clock generation
• Embedded systems utilizing LVCMOS-compatible microcontrollers
• Communication modules needing stable high-frequency timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply rail is stable and within the specified operating range to maintain oscillator performance. Confirm that the PCB footprint matches the 2.0x1.6 mm package dimensions to avoid soldering issues during assembly.

Selection Notes

Select this component when a small form factor and low voltage operation are critical constraints. The LVCMOS output is suitable for general-purpose digital interfaces, while the power-down feature aids in battery-operated applications. Consider the operating temperature range and stability requirements to ensure compatibility with the intended environmental conditions.
