QTM750-30.000MBE-T

Overview

The QTM750-30.000MBE-T is a standard clock oscillator manufactured by TXC Corporation, marketed under the QST brand. It operates at a frequency of 30 MHz with a CMOS output interface. The device functions on a 3.3V supply voltage and features an enable/disable control pin. It utilizes a ceramic quartz resonator element housed in a 4-SMD, no-lead package measuring 7.0x5.0 mm. The unit maintains a frequency stability of +/-50 ppm across an operating temperature range of -40°C to +85°C.

Feature Summary

• CMOS output signal generation for digital logic compatibility
• Integrated enable and disable functionality for power management
• Quartz crystal resonance for high frequency stability
• Surface-mount packaging for automated assembly integration

Applications

• Standard clock signal distribution in electronic circuits
• Timing reference sources for microprocessor systems
• Synchronization modules in communication equipment
• General-purpose clock generation for embedded devices

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by TXC Corporation but distributed under the QST brand name. Confirm the specific package dimensions and lead configuration match your PCB footprint requirements. Ensure the 3.3V supply voltage aligns with your system design before procurement. Check for availability constraints or minimum order quantities associated with the distributor channel.

Selection Notes

Select this component when a stable 30 MHz CMOS clock source is required within a compact surface-mount form factor. The +/-50 ppm stability suits general timing applications rather than precision metrology. Consider the enable/disable feature if power efficiency during idle states is a design priority. Verify that the -40°C to +85°C industrial temperature range meets your environmental operating conditions.

Part Context

This oscillator belongs to the QTM750 series, which offers various frequencies within the same physical footprint. The series provides standardized CMOS outputs suitable for replacing discrete crystal and buffer solutions. It serves as a drop-in replacement for other 7.0x5.0 mm oscillators with compatible electrical specifications.

Replacement Considerations

Direct substitutes include other QTM750 series variants with different frequencies, such as QTM750-25.000MBE-T or QTM750-50.000MBE-T, provided the frequency change is acceptable. Cross-brand replacements require matching the 7.0x5.0 mm package, 3.3V operation, and CMOS output type.
