Overview
The QTM750-40.000MBE-T is a standard CMOS quartz oscillator manufactured by QST. It operates at a nominal frequency of 40 MHz with a frequency stability of ±50 ppm across an industrial temperature range of -40°C to +85°C. The device requires a 3.3V supply voltage and features enable/disable control functionality. It is housed in a compact 4-SMD, no-lead package with body dimensions of 7.0mm x 5.0mm x 1.3mm. The output signal type is CMOS, suitable for digital clock distribution applications.
Feature Summary
- Integrated CMOS output driver for direct logic interface
- Hardware enable/disable pin for power management control
- Industrial-grade temperature range support (-40°C to +85°C)
- Compact surface-mount footprint for space-constrained designs
Applications
- Digital system clock generation
- Microprocessor and microcontroller timing sources
- Communication interface synchronization
- Embedded system timing references
Procurement Notes
Verify the manufacturer designation carefully, as this component appears under both QST and TXC Corporation branding in distributor listings. Confirm the specific suffix 'BE' matches the required enable/disable functionality and voltage specifications. Ensure the operating temperature range aligns with your application's environmental requirements before finalizing procurement.
Selection Notes
Select this oscillator when a 40 MHz CMOS clock source with hardware control is required. Consider the ±50 ppm stability specification against your system's jitter tolerance. The 3.3V supply requirement must match your board's voltage rails. Evaluate the 7x5mm package size against available PCB real estate constraints.
Part Context
This component belongs to the QTM750 series of surface-mount quartz oscillators. The series offers various frequencies and package options from manufacturers including QST and TXC Corporation. The QTM750-40.000MBE-T specifically denotes the 40 MHz variant with enable/disable capability and industrial temperature rating within this standardized product family.
Replacement Considerations
Compatible substitutes include other 40 MHz CMOS oscillators in 7x5mm packages with similar electrical characteristics. Verify that replacement parts maintain the same enable/disable pin configuration and 3.3V operating voltage. Cross-reference frequency stability and temperature range specifications to ensure functional equivalence.
