MSH302548AH-7.3728MHZ-T3

Oscillators Overview

The MSH302548AH-7.3728MHZ-T3 is a standard crystal oscillator (XO) manufactured by MMD, designed for surface-mount applications. It operates at a nominal frequency of 7.3728 MHz with an HCMOS output interface. The device requires a 3.3V supply voltage and features enable/disable functionality for power management. It is housed in a compact 4-SMD, no-lead package measuring 3.40mm x 2.70mm with a maximum height of 1.30mm. The component supports an operating temperature range of -40°C to +85°C and has a maximum supply current of 14mA.

Oscillators Feature Summary

• Integrates enable and disable control pins for active power management
• Utilizes HCMOS logic levels for reliable digital signal interfacing
• Provides stable frequency generation using internal crystal resonance
• Designed for low-profile surface-mount assembly on printed circuit boards

Oscillators Applications

• Real-time clock circuits requiring precise timing基准 signals
• Embedded systems needing standard clock sources for microcontrollers

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 7.3728 MHz specification during procurement. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Ensure the design supports the 3.3V supply rail and accommodates the 14mA maximum current draw. Check for RoHS compliance requirements if applicable to the end product regulations.

Oscillators Selection Notes

Select this component when a standard HCMOS output is required for 3.3V logic systems. The 7.3728 MHz frequency is suitable for baud rate generation in serial communication interfaces. Consider the small 3.40mm x 2.70mm package size for space-constrained designs. Verify that the -40°C to +85°C industrial temperature range meets the environmental conditions of the application.

Oscillators Part Context

This part belongs to the MSH series of surface-mount crystal oscillators from MMD. The series offers various frequencies within a standardized 4-SMD package format. These oscillators are engineered for general-purpose timing applications where moderate stability and low profile are prioritized. The MSH series provides a cost-effective solution for mass-produced electronic devices requiring reliable clock signals.

Oscillators Replacement Considerations

Direct substitutes include other MSH series variants with identical pinouts but different frequencies, such as MSH302548AH-25.000MHZ-T3 or MSH302548AH-4.000MHZ-T3, provided the frequency change is acceptable. Cross-brand replacements must match the 4-SMD no-lead package, 3.3V operation, and HCMOS output type. Verify thermal and electrical compatibility before substituting.
