MH44FAD-R 20.000000

Overview

The MH44FAD-R 20.000000 is a clock oscillator manufactured by MtronPTI, designed for digital circuit timing applications. It operates at a nominal frequency of 20 MHz and supports both 3.3 Volt and 5.0 Volt supply voltages. The device utilizes HCMOS or TTL output logic levels to ensure compatibility with standard digital interfaces. It is housed in an 8-pin DIP package, specifically a half-size metal can configuration, which facilitates through-hole mounting on printed circuit boards. The component is RoHS compliant, indicating adherence to environmental standards regarding restricted hazardous substances.

Feature Summary

• Supports dual voltage operation at 3.3V and 5.0V for flexible system integration
• Features low jitter performance to maintain signal integrity in high-speed circuits
• Offers a tristate option for advanced control over signal output states

Applications

• Digital communication systems requiring precise clock synchronization
• Microprocessor and microcontroller clock generation circuits
• Test and measurement equipment timing references

Procurement Notes

Verify the specific suffix requirements for your application, as the -R suffix denotes RoHS compliance. Confirm that the 8-pin DIP half-size metal can package aligns with your PCB footprint and assembly capabilities. Ensure the selected voltage version matches your system's power supply rails, as the device supports both 3.3V and 5.0V options. Check for any specific temperature range requirements if operating in extreme environments, as wide temperature variants may be available within the series.

Selection Notes

Select this component when a reliable, low-jitter clock source is needed for HCMOS or TTL logic families. The choice between 3.3V and 5.0V operation should be dictated by the target circuit's voltage levels. Consider the physical size constraints of the half-size DIP package against available board space. Evaluate the need for a tristate function if bus sharing or power-down modes are required in the design.

Part Context

This part belongs to the M3H & MH Series from MtronPTI, which specializes in precision clock oscillators. These devices are engineered to provide stable frequency outputs for various electronic applications.
