QTT252-26.000MDG-T

Overview

The QTT252-26.000MDG-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST Products, LLC. It operates at a nominal frequency of 26 MHz and utilizes a quartz resonator with a clipped sine wave output format. The device features a compact 2.5x2.0 mm package and supports a supply voltage of 1.8V. It provides high frequency stability of ±500ppb across an operating temperature range of -30°C to +85°C.

Feature Summary

• High frequency stability of ±500ppb over the full industrial temperature range
• Compact 2.5x2.0 mm surface-mount package design
• Clipped sine wave output signal format

Applications

• Wireless communication modules requiring precise timing
• Portable electronic devices with limited space constraints
• Industrial control systems operating in variable temperatures

Procurement Notes

Verify the specific manufacturer designation as QST Products, LLC, distinct from other entities using similar nomenclature. Confirm that the 1.8V supply voltage requirement aligns with the target circuit design. Ensure compatibility with the clipped sine wave output interface for downstream logic or amplifier stages. Validate the ±500ppb stability specification against system jitter requirements.

Selection Notes

Select this component when ultra-high stability is required within a minimal footprint. The 1.8V operation makes it suitable for low-power battery-operated applications. Consider the clipped sine wave output characteristics for signal integrity needs. Compare against standard VCXOs if tuning range is not a primary requirement.
