QTM252-62.500MBE-T

Overview

The QTM252-62.500MBE-T is a standard CMOS quartz oscillator manufactured by QST, operating at a fixed frequency of 62.5 MHz. It utilizes a ceramic base resonator and features a surface-mount SMD package with dimensions of 2.5 x 2.0 mm and a maximum seated height of 0.90 mm. The device supports a supply voltage of 3.3V and offers a frequency stability of ±50 ppm across an industrial temperature range of -40°C to +85°C. It delivers low phase jitter of 1 ps RMS and includes a tri-state enable pin for power management.

Feature Summary

• Ultra-compact 2520 surface-mount package reduces board space requirements
• Low electromagnetic interference (EMI) characteristics suitable for high-speed designs
• Integrated tri-state control pin enables precise clock output management
• Industrial-grade thermal stability ensures reliable operation in varying environments

Applications

• High-speed serial bus reference clocks including PCIe and SATA
• Wireless communication modules such as WLAN and Bluetooth
• Consumer electronics like IP cameras and digital cameras
• Industrial storage devices and server infrastructure

Procurement Notes

Verify the specific suffix codes against official QST documentation to confirm voltage levels and tolerance grades. Ensure compatibility with your PCB footprint and reflow soldering profiles. Confirm availability through authorized distributors as stock levels fluctuate. Request updated datasheets to validate current manufacturing status and compliance certifications before finalizing procurement orders.

Selection Notes

Choose this component when board real estate is limited and low jitter performance is critical for signal integrity. The 2520 package fits applications where larger oscillators cannot be accommodated. Select this part for designs requiring robust industrial temperature performance without sacrificing speed. Consider the tri-state feature if system-level power saving during idle states is a design priority.

Part Context

This model belongs to the QTM252 series of CMOS active crystal oscillators designed for compact electronic systems. The series emphasizes miniaturization while maintaining high-frequency stability and low noise performance. It serves as a direct replacement for larger legacy oscillators in modern portable and industrial devices requiring precise timing references.

Replacement Considerations

Check equivalent parts from other manufacturers offering similar 2520 footprints and 62.5 MHz frequencies. Verify that substitute components match the 3.3V supply requirement and ±50 ppm stability specifications. Ensure the alternative part supports the same industrial temperature range and CMOS output logic levels.
