Overview
The QTM325-114.285MBE-T is a standard surface-mount CMOS quartz oscillator manufactured by TXC Corporation under the QST brand. It operates at a frequency of 114.285 MHz with a stability tolerance of ±50 ppm across an industrial temperature range of -40°C to +85°C. The device utilizes a 3.3V supply voltage and features a 4-pin CSMD package with dimensions of 3.2mm x 2.5mm.
Feature Summary
- Provides stable clock signals using quartz crystal technology
- Designed for surface-mount integration in compact electronic assemblies
- Operates within specified industrial temperature ranges
Applications
- Digital signal processing systems
- Communication equipment requiring precise timing
- Embedded control circuits
Procurement Notes
Verify the manufacturer designation, as sources list both TXC Corporation and QST. Confirm the specific ordering suffix matches the required frequency and voltage specifications. Ensure the package type corresponds to the 4-pin CSMD configuration. Check for RoHS3 compliance status if environmental regulations apply to your project requirements.
Selection Notes
Select this component when a 114.285 MHz clock source is required for CMOS-compatible logic interfaces. The ±50 ppm stability suits general digital applications rather than high-precision RF uses. Consider the 3.2x2.5mm footprint for PCB layout constraints. Verify that the 3.3V operating voltage aligns with the target system power rails.
Part Context
This part belongs to the QTM series of standard oscillators from TXC Corporation. The series offers various frequencies and package sizes for different application needs. The QTM325 variant specifically denotes the 3.2x2.5mm form factor. These components are widely used in consumer electronics and industrial controls.
Replacement Considerations
Direct substitutes include other 114.285 MHz CMOS oscillators with identical 3.2x2.5mm footprints and 3.3V operation. Verify pin compatibility and electrical parameters before substitution. Cross-reference with similar models like QTM325-50.000MBE-T for form factor consistency.
