QTM252J-27.000MBJ-T

Overview

The QTM252J-27.000MBJ-T is a standard CMOS quartz oscillator manufactured by QST Products, LLC. It operates at a frequency of 27 MHz with a supply voltage of 3.3V and a maximum current consumption of 22mA. The device features a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to +105°C. Housed in a compact 4-SMD, No Lead surface-mount package, it includes enable/disable control functionality for power management.

Feature Summary

• CMOS output interface suitable for digital logic integration
• Integrated enable and disable pin for active power control
• Industrial-grade wide temperature operation capability

Applications

• General-purpose clock signal generation
• Embedded system timing references
• Consumer electronics requiring low-power standby modes

Procurement Notes

Verify the specific suffix 'MBJ' against the manufacturer's official datasheet to confirm voltage levels and tolerance specifications. Ensure the ordering quantity aligns with the manufacturer's minimum packaging requirements. Confirm that the industrial temperature rating meets the environmental constraints of the target application before finalizing procurement.

Selection Notes

Select this component when a 27 MHz reference is required for 3.3V logic systems. The integrated enable feature allows for dynamic power reduction during idle states. Verify compatibility with the host controller's input threshold levels. Consider the ±50ppm stability if precise synchronization is not critical compared to tighter tolerance alternatives.

Part Context

This part belongs to the QTM252 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options within a small form factor. The J suffix typically denotes specific electrical characteristics or packaging variations within the product line. It serves as a direct replacement for legacy through-hole oscillators in space-constrained designs.

Replacement Considerations

Check pinout compatibility with existing PCB layouts. Verify that the new oscillator's start-up time meets the system initialization requirements. Ensure the load capacitance matches the design specifications to maintain accurate frequency performance.
