18QHTF21-10.94929-OE

Overview

The 18QHTF21-10.94929-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.94929 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable functionality for power management
• Utilizes a leadless surface-mount package for automated assembly

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded devices utilizing standard crystal oscillator interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout to prevent soldering defects during assembly.

Selection Notes

Select this component when a precise 10.94929 MHz timing source is required within a low-voltage 1.8V environment. Consider the enable/disable feature if dynamic power saving is necessary. Evaluate the small 2.0x1.6 mm form factor against available board space constraints compared to larger oscillator packages.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series typically offers various frequencies and voltage options. The 'OE' suffix often denotes specific packaging or ordering configurations. Mercury Electronics specializes in quartz-based frequency control products including crystals and oscillators.

Replacement Considerations

Direct replacements must match the 10.94929 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm footprint. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before substituting with components from other manufacturers.
