18QHTF21-4.560-PD

Oscillators Overview

The 18QHTF21-4.560-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 4.56 MHz and utilizes LVCMOS output levels. The device is powered by a 1.8V supply voltage and includes 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.

Oscillators Feature Summary

• Supports low-voltage operation with 1.8V supply
• Integrates standby mode for power reduction
• Provides LVCMOS signal compatibility

Oscillators Applications

• General clock generation circuits
• Frequency reference modules
• Embedded system timing synchronization

Oscillators Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and thermal characteristics. Ensure the 4-SMD no-lead footprint matches the target PCB layout. Confirm that the LVCMOS output swing aligns with the receiving logic family requirements before finalizing the order.

Oscillators Selection Notes

Select this component when a stable 4.56 MHz reference is required in space-constrained designs. The 1.8V specification suits low-power digital systems. Consider the standby feature if power efficiency is critical. Verify that the package dimensions fit within the mechanical constraints of the assembly.

Oscillators Part Context
