Overview
The QTM750-48.000MBE-T is a standard CMOS quartz oscillator manufactured by QST Products LLC. It operates at a nominal frequency of 48 MHz with a supply voltage of 3.3V DC. The device features an enable/disable control function and utilizes a 4-SMD, no-lead package with dimensions of 7x5x1.3mm. Frequency stability is rated at ±50ppm over the operating temperature range of -40°C to +85°C.
Feature Summary
- Integrated CMOS output driver for direct digital interface compatibility
- Active enable/disable control pin for power management optimization
- Robust ceramic construction ensuring stable performance across industrial temperature ranges
Applications
- General-purpose clock generation in embedded systems
- Data communication interface timing sources
- Microcontroller system clocks requiring precise frequency stability
Procurement Notes
Verify the manufacturer designation carefully, as this component appears under both TXC Corporation and QST Products LLC listings in distributor databases. Confirm the specific datasheet version matches the required electrical characteristics. Ensure the ordering suffix corresponds to the correct tape-and-reel packaging quantity specified by the supplier. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when a 48 MHz reference signal is required with low power consumption capabilities. The 3.3V supply voltage makes it suitable for modern logic families. Consider the ±50ppm stability specification against system jitter requirements. The compact 7x5mm footprint aids in dense PCB layouts where space is constrained compared to larger oscillator packages.
Part Context
This part belongs to the QTM750 series of surface-mount oscillators. The series offers various frequency options including 32.768 MHz, 50 MHz, and others within the same physical form factor. The MBE suffix typically denotes specific packaging and tolerance configurations within the product line.
Replacement Considerations
Direct substitutes include other 48 MHz CMOS oscillators in 7x5mm SMD packages from manufacturers such as Epson or SiTime, provided they match the 3.3V supply and enable pin functionality. Verify pinout compatibility before swapping.
