QTM252J-8.000MBJ-T

Overview

QTM252J-8.000MBJ-T is a standard clock oscillator manufactured by QST, housed in a 2.5x2.0 mm surface-mount package. It operates at a frequency of 8.000 MHz with CMOS output and supports a 3.3V supply voltage. The device provides ±50ppm frequency stability across an operating temperature range of -40°C to +105°C.

Feature Summary

• CMOS output interface for digital logic compatibility
• Low profile 2.5x2.0 mm SMD package design
• Integrated enable/disable control function

Applications

• General purpose timing circuits
• Embedded system reference clocks
• Consumer electronics timing sources

Procurement Notes

Verify the specific suffix 'B' against official documentation to confirm the exact supply voltage rating, as variations exist within the QTM252J series. Ensure the required frequency stability meets the ±50ppm specification for the target application environment. Confirm that the operating temperature range covers the full operational spectrum of the end product.

Selection Notes

Select this component when a compact footprint is required for low-frequency timing applications. The CMOS output is suitable for direct interfacing with digital processors. Consider the ±50ppm stability limit if higher precision is needed, and verify the 3.3V supply requirement aligns with the system power architecture.

Part Context

The QTM252J series represents a line of low-jitter quartz oscillators designed for space-constrained designs. This specific model utilizes a ceramic resonator element within a small outline package, offering a balance between performance and size for modern electronic assemblies.

Replacement Considerations

Direct substitutes include other 2520 package CMOS oscillators from different manufacturers with matching 8MHz frequency and 3.3V operation. Verify pinout compatibility and electrical parameters before substitution.
