QTM532-25.000MDE-T

Overview

The QTM532-25.000MDE-T is a surface-mount CMOS crystal oscillator manufactured by QST Products, LLC. It operates at a nominal frequency of 25 MHz with a frequency stability of ±50 ppm across the industrial temperature range of -40°C to +85°C. The device requires a supply voltage of 1.8V and features a standard XO output type. Its physical dimensions are 5.00mm in length and 3.20mm in width, housed in a compact SMD package suitable for space-constrained electronic designs.

Feature Summary

• CMOS output interface for digital logic compatibility
• Industrial temperature range operation from -40°C to +85°C
• Compact 5.00mm x 3.20mm surface mount footprint

Applications

• Digital signal processing circuits
• Communication equipment clock sources
• Embedded system timing references

Procurement Notes

Verify the manufacturer designation carefully, as listings may attribute this part to QST Products, LLC or TXC Corporation due to corporate relationships. Confirm the specific suffix 'MDE' matches the required 1.8V supply and ±50ppm stability specifications. Ensure the ordering documentation explicitly states the 25MHz frequency and CMOS output type to avoid confusion with other variants in the QTM532 series that may differ in voltage or load requirements.

Selection Notes

Select this component when a low-voltage 1.8V CMOS oscillator is required for 25MHz applications. The ±50ppm stability is suitable for general-purpose timing where high precision is not critical. Consider the 5x3.2mm package size for PCB layout constraints. Verify that the operating temperature range of -40°C to +85°C meets the environmental conditions of the target application before finalizing the selection.

Part Context

This part belongs to the QTM532 series of quartz oscillators produced by QST. The series offers various frequencies and supply voltages, with the MDE suffix specifically denoting the 25MHz frequency, 1.8V supply, and CMOS output configuration. These components are designed for use in portable electronics and communication devices requiring reliable clock signals in a small form factor.
