QTM252J-24.000MDJ-T

Overview

The QTM252J-24.000MDJ-T is a standard CMOS quartz oscillator manufactured by TXC Corporation, operating at a frequency of 24 MHz. It utilizes a 2.5x2.0 mm surface-mount package and functions with a supply voltage of 1.8V. The device features an enable/disable control function and offers a frequency stability of ±50ppm across an operating temperature range of -40°C to +85°C.

Feature Summary

• CMOS output interface for digital logic compatibility
• Integrated enable and disable control pin
• Low jitter performance suitable for high-speed designs
• Industrial temperature range operation

Applications

• SSD controller reference clocks
• Bluetooth module timing in wearable devices
• High-speed bus clock generation (PCIe, USB)
• WLAN and wireless communication systems

Procurement Notes

Verify the manufacturer designation carefully, as the part number prefix may indicate TXC Corporation despite the brand query. Confirm the specific suffix 'MDJ' aligns with the required voltage and stability specifications. Ensure the order quantity meets the factory reel packaging requirements. Cross-reference the datasheet version to confirm the operating temperature range and electrical characteristics match the design intent.

Selection Notes

Select this component when a compact 2520 footprint is required alongside low phase jitter for signal integrity. The 1.8V supply voltage suits modern low-power digital interfaces. The enable pin allows for power management during sleep states. Consider the ±50ppm stability for general-purpose timing where tighter tolerances are not critical.

Part Context

This model belongs to the QTM252 series of low-jitter CMOS oscillators. The series covers various frequencies from 4MHz to 125MHz, providing a versatile solution for consumer and industrial applications. The 2520 package size facilitates space-constrained PCB layouts while maintaining robust performance standards for clock distribution networks.

Replacement Considerations

Direct substitutes within the same series include QTM252E variants for different voltage levels or EMI specifications. Other models like QT252S represent passive crystals requiring external driver circuits, which are not direct functional replacements. Verify pinout and electrical parameters before swapping.
