QTM252-12.800MBD-T

Overview

The QTM252-12.800MBD-T is a standard CMOS quartz oscillator manufactured by QST, operating at a nominal frequency of 12.8 MHz. It features a ±25 ppm frequency stability and operates on a 3.3V supply voltage. The device utilizes a 4-SMD, no-lead package with dimensions of 2.5mm x 2.0mm. It supports an operating temperature range of -40°C to +85°C and offers an enable/disable function for power management.

Feature Summary

• CMOS output interface compatible with standard digital logic
• Integrated enable and disable control functionality
• Compact surface-mount design for space-constrained applications

Applications

• General-purpose clock generation in embedded systems
• Timing reference for microprocessors and microcontrollers
• Communication interface synchronization circuits

Procurement Notes

Verify the specific suffix codes against official QST documentation to ensure correct voltage and stability specifications. Confirm that the ordering information matches the required operational temperature range and package type. Cross-reference distributor part numbers with manufacturer identifiers to avoid sourcing errors during procurement.

Selection Notes

Select this component when a 12.8 MHz CMOS clock signal is required with moderate stability. Ensure the system design accommodates the 3.3V supply requirement and the physical footprint of the 2.5x2.0mm SMD package. Consider the enable/disable feature if power efficiency during idle states is a priority for the application.

Part Context

This oscillator belongs to the QTM252 series from QST, designed for timing applications requiring small form factors. The series provides various frequency options and voltage levels within the same mechanical envelope, allowing for flexible design integration across different electronic products while maintaining consistent mounting characteristics.
