Overview
The QTM325-19.200MBE-T is a standard CMOS quartz oscillator manufactured by QST, designed for surface-mount applications. It operates at a fixed frequency of 19.2 MHz with a supply voltage of 3.3V DC. The device utilizes a ceramic base resonator and provides an enable/disable function for power management. It features a compact 3.2mm x 2.5mm package with a height of 1.0mm. The unit supports an operating temperature range from -40°C to +85°C and maintains a frequency stability of +/-50ppm across this range.
Feature Summary
- Integrates an enable/disable control function for efficient power management
- Utilizes a ceramic base resonator for stable signal generation
- Supports surface-mount technology in a compact 3.2x2.5mm footprint
Applications
- General clock signal generation in embedded systems
- Timing reference for digital logic circuits
- Communication interface synchronization modules
Procurement Notes
Verify the manufacturer designation carefully, as the part number prefix may appear associated with TXC Corporation in certain distributor databases despite QST being the primary brand identifier for this specific series. Confirm the active status and RoHS3 compliance through official documentation before integration. Ensure the 3.3V supply requirement aligns with the target circuit design parameters.
Selection Notes
Select this component when a precise 19.2 MHz timing source is required within a constrained board area. The 3.2x2.5mm package offers a balance between size and performance for portable electronics. Consider the +/-50ppm tolerance suitable for standard communication protocols. The enable pin allows for dynamic power control, making it appropriate for battery-operated devices requiring extended standby life.
Part Context
This oscillator belongs to the QTM325 series, which represents a line of surface-mount quartz oscillators. The series is characterized by its small form factor and compatibility with standard CMOS logic levels. These components are widely used in consumer electronics and industrial equipment where reliable clock signals are essential for system operation and data integrity.
Replacement Considerations
Direct substitutes must match the 19.2 MHz frequency, 3.2x2.5mm package, and 3.3V operation. Verify that alternative sources provide identical enable/disable functionality and maintain the same +/-50ppm stability over the specified temperature range.
