QTM216J-48.000MBJ-T

Overview

The QTM216J-48.000MBJ-T is a surface-mount CMOS oscillator manufactured by QST, designed for standard clock applications. It operates at a nominal frequency of 48 MHz with a frequency stability of ±50 ppm. The device requires a 3.3V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, no-lead package measuring 2.0x1.6 mm. The component supports an operating temperature range of -40°C to +105°C and draws a maximum supply current of 22 mA.

Feature Summary

• Integrated enable/disable functionality for power management
• Low electromagnetic interference (EMI) CMOS output
• Compact 2.0x1.6 mm surface-mount footprint

Applications

• Standard clock signal generation in embedded systems
• Timing reference for microprocessors and digital logic
• Consumer electronics requiring precise frequency sources

Procurement Notes

Verify the exact suffix 'MBJ-T' matches the required frequency, load capacitance, and temperature grade. Confirm that the 3.3V supply and CMOS output levels align with the target circuit design. Ensure the 4-SMD package dimensions fit the PCB layout constraints. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this model when a 48 MHz timing source with ±50 ppm stability is required within a -40°C to +105°C environment. The 3.3V supply and enable pin make it suitable for power-sensitive designs. Compare against the QTM216E series if lower EMI or different temperature ranges are needed. Ensure the 22 mA max current consumption fits the system power budget.

Part Context

This component belongs to the QTM216 family of low-profile oscillators from QST. The J suffix typically denotes specific electrical characteristics such as temperature range and load capacitance compared to other variants like the E series. These devices are widely used in portable and industrial applications where space and power efficiency are critical constraints.

Replacement Considerations

Direct substitutes include other QTM216J variants with different frequencies, such as QTM216J-16.000MBJ-T. For similar performance, consider QTM216E-24.000MBM-T if the temperature range and EMI specifications allow. Verify pin compatibility and electrical parameters before substitution.
