QTM252-27.000MBE-T

Overview

The QTM252-27.000MBE-T is a standard clock oscillator manufactured by TXC Corporation, part of the QTM252 series. It features a 2.5x2.0 mm surface-mount package and utilizes CMOS output logic. The device operates at a nominal frequency of 27.000 MHz with a supply voltage of 3.3V. Frequency stability is specified at +/-50ppm over an operating temperature range of -40°C to +85°C. The component is supplied in a reel packaging format.

Feature Summary

• Compact 2.5x2.0 mm surface-mount footprint designed for space-constrained applications
• CMOS output interface compatible with standard digital logic levels
• Industrial temperature rating supporting operation from -40°C to +85°C

Applications

• Standard clock generation for embedded systems
• Reference clocks for consumer electronics
• Timing signals for industrial control equipment

Procurement Notes

Verify the manufacturer designation carefully, as official documentation lists TXC Corporation as the producer for this specific model number. Confirm that the required supply voltage matches the 3.3V specification provided in the datasheet. Ensure the operating environment remains within the stated -40°C to +85°C range to maintain the guaranteed +/-50ppm frequency stability. Check current availability status through authorized distributors, as stock levels may vary.

Selection Notes

Select this component when a small form factor is required alongside standard CMOS compatibility. The 27MHz frequency is suitable for general-purpose timing needs rather than high-speed serial interfaces requiring lower jitter. Consider the +/-50ppm stability sufficient for most non-critical synchronization tasks. Evaluate if the 3.3V supply aligns with the target system's power rails before finalizing the design.

Part Context

This oscillator belongs to the QTM252 series, which offers various frequencies and voltage options within the same 2.5x2.0 mm package. Other variants in the series support different voltages such as 2.5V or 1.8V and offer tighter stability specifications like +/-25ppm. The series is designed to provide a unified solution for manufacturers needing consistent footprints across multiple product lines.

Replacement Considerations

Direct substitutes include other QTM252 series parts with matching 27MHz frequency and 3.3V operation. Verify pinout compatibility and electrical characteristics before swapping with generic equivalents. Ensure any replacement maintains the same package dimensions and thermal performance ratings.
