18QHTF21-11.2941-OE

Overview

The 18QHTF21-11.2941-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 11.2941 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for applications requiring precise timing signals within low-voltage digital systems.

Feature Summary

• Supports LVCMOS output logic for direct interface with digital circuits
• Features 1.8V operating voltage with enable/disable control capability
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• Clock signal generation for embedded systems
• Timing reference for microcontrollers
• Data communication interfaces requiring stable frequency sources

Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the 1.8V supply voltage aligns with the target circuit design. Confirm that the enable/disable functionality meets the system's power management requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-profile 2.0x1.6 mm footprint is required for space-constrained designs. The 11.2941 MHz frequency suits specific baud rate or clock division needs. Consider the LVCMOS output level compatibility with downstream logic families. The enable pin allows for dynamic power saving during idle periods in battery-operated devices.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized small outline package. The series supports both standard and spread-spectrum options. The 1.8V variant targets modern low-power portable electronics. Mercury Electronics leverages decades of quartz crystal manufacturing expertise to produce these frequency control components.

Replacement Considerations

Direct substitutes must match the 11.2941 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent enable/disable functionality. Cross-reference with other manufacturers offering similar low-profile oscillators if availability is constrained.
