18QHTF21-11.600-PD

Overview

The 18QHTF21-11.600-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.6 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features a standby mode to reduce power consumption when inactive
• Utilizes a small surface-mount package for space-constrained designs

Applications

• General clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring stable clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 1.8V logic systems. Consider the operating temperature range and frequency stability needs relative to the application environment. Evaluate the power-down feature if battery life or thermal management is a critical constraint in the final product design.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies within the standard XO category. The manufacturer specializes in quartz crystals and frequency control products, providing components for diverse electronic applications requiring precise timing signals.

Replacement Considerations

Direct substitutes include other 11.6 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Verify pinout compatibility and electrical parameters such as supply voltage and output swing before substitution.
