18QHTF21-11.0599-OE

Overview

The 18QHTF21-11.0599-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 11.0599 MHz with LVCMOS output logic. The device supports 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

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 11.0599 MHz
• Embedded devices utilizing LVCMOS interfaces

Procurement Notes

Verify the exact frequency tolerance and operating temperature range specifications against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package footprint matches the PCB layout requirements to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 11.0599 MHz timing source is required for low-voltage digital applications. The LVCMOS output ensures direct interfacing with compatible logic families without additional level shifting. The enable/disable feature allows for power management in battery-operated or energy-efficient designs where the clock can be deactivated when not in use.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and supply voltages, all sharing the same compact 2.0x1.6mm form factor.
