18QHTF21-1.600-OE

Overview

The 18QHTF21-1.600-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.6 MHz and utilizes an LVCMOS output interface. The device supports a supply voltage of 1.8V and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface mount applications.

Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable and disable control capability
• Standard quartz oscillator design for precise timing

Applications

• Timing and clock signal generation in electronic devices
• General purpose digital circuit synchronization
• Embedded system clock sources

Procurement Notes

Verify the specific frequency suffix matches the required 1.6 MHz specification. Confirm the 1.8V operating voltage aligns with the target system design. Ensure the 4-SMD no-lead package footprint fits the PCB layout constraints. Check datasheet for tolerance and stability requirements before finalizing procurement.

Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required. The enable/disable feature allows for dynamic power control. Consider the 1.6 MHz frequency requirement specifically. The small form factor suits space-constrained designs. Verify compatibility with downstream logic levels.

Part Context

This part belongs to the QuikXO series of fast-delivery CMOS output clock oscillators from Mercury Electronics. The series offers both standard and custom frequencies. The 18QHTF21 model line provides reliable timing solutions using quartz crystal technology established by the manufacturer since 1973.

Replacement Considerations

Compatible substitutes include other 1.6 MHz LVCMOS oscillators with 1.8V operation and similar package dimensions. Verify pinout compatibility and electrical specifications match exactly. Cross-reference with Mercury's official substitution lists if available.
