18QHTF21-110.050-PD

Overview

The 18QHTF21-110.050-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 110.05 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby (power down) function to reduce power consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package, designed for surface mount applications. This component is suitable for systems requiring precise timing signals with low power requirements.

Feature Summary

• Integrates a standby (power down) function for energy efficiency
• Delivers LVCMOS output logic for standard digital interfacing
• Operates on a single 1.8V supply voltage

Applications

• Low-power electronic designs
• Digital signal processing systems
• Communication equipment requiring precise clocking

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD, No Lead package dimensions fit within your PCB layout constraints. Check for any specific operating temperature range limitations if used in extreme environments.

Selection Notes

Select this model when a 110.05 MHz clock signal is required with minimal power consumption. The LVCMOS interface ensures compatibility with standard logic families. Consider the standby feature for battery-operated or power-sensitive applications. Verify that the 1.8V supply voltage is available in your design. The surface mount package facilitates automated assembly processes.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages.
