18QHTF21-60.606-PD

Overview

The 18QHTF21-60.606-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 60.606 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down function to reduce consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power management
• Compact 4-SMD no-lead surface mount package

Applications

• Battery-powered portable devices
• General-purpose clock signal generation
• Digital circuit timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. 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. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under expected environmental conditions.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The integrated power-down feature makes it suitable for energy-efficient designs. Consider the small form factor if space is limited on the printed circuit board. Validate that the 60.606 MHz frequency meets the specific clocking needs of the target application without requiring external dividers.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a manufacturer with extensive experience in quartz crystal production. The series typically offers various frequencies within a standardized 4-SMD package. This specific model provides a fixed 60.606 MHz output, distinguishing it from other variants in the lineup that may offer different frequencies or voltage levels.

Replacement Considerations

Direct substitutes include other 18QHTF21 series models with identical pinout and voltage specifications but different frequencies, such as 18QHTF21-6.000-PD or 18QHTF21-68.665-PD, provided the frequency difference is acceptable for the application.
