QTM252J-10.000MBJ-T

Overview

The QTM252J-10.000MBJ-T is a standard clock oscillator manufactured by QST, designed for high-density circuit applications. It operates at a frequency of 10 MHz with a CMOS output signal type. The device supports a supply voltage of 3.3 V and features an enable/disable control function. It utilizes a 4-SMD, No Lead surface-mount package with dimensions of 2.5x2.0 mm. The unit maintains a frequency tolerance of +/-50 ppm across an operating temperature range of -40°C to +105°C.

Feature Summary

• Compact SMD2520-4P surface-mount form factor suitable for space-constrained designs
• Integrated enable and disable functionality for power management
• Low jitter and phase noise characteristics for stable clock signals

Applications

• High-density circuit board designs
• Digital communication systems requiring precise timing
• Embedded systems with strict size limitations

Procurement Notes

Verify the manufacturer designation carefully, as sources may list TXC Corporation or QST due to corporate relationships. Confirm the specific suffix MBJ corresponds to the required 3.3V supply and enable/disable pin configuration. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement orders.

Selection Notes

Select this component when a small footprint is critical alongside standard CMOS compatibility. The 3.3V supply requirement must align with the system logic levels. Consider the +/-50 ppm tolerance sufficient for general digital interfaces. Verify that the enable/disable feature integrates correctly with the host controller's GPIO capabilities for efficient power cycling.

Part Context

This oscillator belongs to the QTM252 series, characterized by its 2.5x2.0 mm ceramic package. The series offers various frequencies and voltage options, including 1.8V and 2.5V variants. The J suffix typically denotes specific performance attributes like low jitter within the product line.

Replacement Considerations

QTM252J-10.000MCJ-T: Similar form factor but may differ in voltage or tolerance specifications. QTM252E-10.000MBJ-T: Alternative variant potentially offering different EMI characteristics. Always cross-reference datasheets for pinout and electrical parameter compatibility.
