18QHTF21-12.960-OE

Overview

The 18QHTF21-12.960-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 12.96 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead surface-mount package, suitable for space-constrained electronic designs requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output interface for direct digital logic compatibility
• Features active enable/disable pin for flexible power control
• Utilizes low-profile 4-SMD no-lead surface mount packaging

Applications

• Digital signal processing clock sources
• Embedded system timing references
• Communication equipment synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD footprint matches the PCB layout constraints. Request the latest manufacturing documentation to validate RoHS compliance status and lead time estimates directly from authorized distributors.

Selection Notes

Select this component when a stable 12.96 MHz reference is required with minimal power consumption. The integrated enable feature allows for dynamic power saving in battery-operated devices. Consider the LVCMOS output swing limits to ensure compatibility with downstream logic families. Evaluate the thermal performance of the small form factor if operating in high-density assemblies.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequency options within a consistent 4-SMD package. The suffix OE typically denotes specific ordering or environmental configurations. This model provides a cost-effective solution for general-purpose timing applications where moderate accuracy suffices.

Replacement Considerations

Direct substitutes include other 12.96 MHz XO models with identical 4-SMD footprints and 1.8V LVCMOS outputs. Verify pinout compatibility and electrical specifications before swapping. Cross-reference with similar Mercury Electronics variants such as the 18QHTF21-1.545-OE for different frequencies.
