QTM216J-24.000MDJ-T

Overview

The QTM216J-24.000MDJ-T is a surface-mount CMOS oscillator manufactured by QST, operating at a nominal frequency of 24 MHz. It functions as a standard XO type with an enable/disable control feature. The device requires a 1.8V supply voltage and utilizes a crystal as its basic resonator. It is housed in a compact 4-SMD, no-lead package measuring 2.0mm x 1.6mm. The unit supports an output load of 15 pF and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates enable/disable functionality for power management
• Utilizes low electromagnetic interference CMOS output
• Features a compact surface-mount footprint for space-constrained designs

Applications

• Consumer electronics requiring precise timing signals
• Industrial control systems needing reliable clock sources
• Communication equipment utilizing standard CMOS interfaces

Procurement Notes

Verify the specific suffix 'MDJ' confirms the 1.8V supply voltage requirement, as other suffixes in the QTM216 series may indicate different voltage levels such as 3.3V. Ensure the order quantity matches the available packaging options, which typically include tape and reel configurations. Confirm that the lead time aligns with project schedules, noting that standard delivery periods may vary based on manufacturer stock levels and regional distribution channels.

Selection Notes

Select this component when a 24 MHz clock signal is required with a 1.8V logic interface. The enable pin allows for dynamic power control, making it suitable for battery-operated devices. Compare against the QTM216E series if a 3.3V supply is necessary instead. Ensure the PCB layout accommodates the 2x1.6mm SMD package dimensions and provides adequate thermal relief for operation across the specified industrial temperature range.

Part Context

This part belongs to the QTM216 family of timing devices produced by QST Products, LLC. The series offers various frequency and voltage combinations within a standardized small outline package. The J suffix typically denotes specific electrical characteristics or packaging variations within the product line, distinguishing it from other variants like the E series which may support higher voltages.

Replacement Considerations

Direct substitutes include the QTM216E-24.000MDJ-T, provided the system can accommodate the potential voltage difference if the E series variant differs in supply requirements. Verify pin compatibility and electrical specifications before swapping components to ensure circuit integrity.
