QTM252-20.000MBA-T

Overview

The QTM252-20.000MBA-T is a standard clock oscillator manufactured by TXC Corporation, categorized under the QTM252 series. It operates at a nominal frequency of 20 MHz with a frequency stability of ±25 ppm. The device utilizes CMOS output format and requires a 3.3V supply voltage. It is designed for surface mount applications in a compact 2.5mm x 2mm package. The operational temperature range spans from -40°C to +85°C, ensuring reliability across various industrial environments.

Feature Summary

• CMOS output interface suitable for digital logic integration
• Compact surface-mount footprint for space-constrained designs
• Wide operating temperature range for industrial durability

Applications

• General-purpose digital clock signal generation
• Microcontroller system timing references
• Embedded communication interface synchronization

Procurement Notes

Verify manufacturer designation as TXC Corporation despite distributor branding. Confirm package dimensions match 2.5x2mm specifications. Ensure supply voltage aligns with 3.3V requirements. Check frequency tolerance matches ±25 ppm needs. Validate temperature range covers intended operational extremes.

Selection Notes

Select this component when a stable 20MHz reference is required for CMOS-based circuits. Consider the ±25 ppm stability for general timing applications. Evaluate the 3.3V supply constraint against system power rails. Assess the -40 to 85°C range against environmental conditions. Compare physical size constraints with available board space.

Part Context

This part belongs to the QTM252 series of quartz crystal oscillators. It shares the same form factor and electrical characteristics with other variants in the family, differing primarily in frequency and stability ratings. The series is designed for high-volume surface-mount assembly processes.

Replacement Considerations

Direct substitutes include QTM252-20.000MBE-T with ±50 ppm stability. Other compatible options within the QTM252 series may offer different frequency points or tolerance levels while maintaining identical pinout and mechanical dimensions.
