QTM252J-20.000MDJ-T

Overview

The QTM252J-20.000MDJ-T is a standard CMOS quartz oscillator in a 2.5x2.0mm surface-mount package. It operates at a fixed frequency of 20 MHz with a supply voltage of 1.8V. The device features an enable/disable function and offers a frequency stability of ±50ppm over the -40°C to +105°C temperature range. Designed for low jitter and phase noise applications, it supports industrial-grade environments.

Feature Summary

Compact 2.5x2.0mm surface-mount ceramic package suitable for space-constrained designs
Integrated enable and disable control functionality for power management
Low jitter and phase noise characteristics optimized for high-speed digital interfaces

Applications

Industrial system clock generation
Automotive electronic timing references
Medical system synchronization
Network communication equipment clocks

Procurement Notes

Verify the specific suffix 'MDJ' against the manufacturer's current datasheet to confirm the exact voltage, stability, and temperature grade specifications. Ensure the enable pin configuration matches the target circuit design requirements before finalizing the bill of materials.

Selection Notes

Select this component when a 1.8V supply and 20MHz frequency are required within a 2.5x2.0mm footprint. Consider the ±50ppm stability specification for general industrial applications. Evaluate the enable pin logic compatibility with the host microcontroller or FPGA interface.

Part Context

This part belongs to the QTM252 series of low-jitter CMOS oscillators manufactured by QST (TXC). The series provides various frequency options and voltage levels within the same compact 2520 package format, catering to diverse consumer, industrial, and automotive timing needs.

Replacement Considerations

Direct substitutes include other 20MHz 1.8V CMOS oscillators in 2520 packages from manufacturers such as TXC or Epson, provided they match the ±50ppm stability and enable pin functionality.
