QTM216J-7.3728MBJ-T

Overview

The QTM216J-7.3728MBJ-T is a surface-mount crystal oscillator manufactured by QST, designed for low electromagnetic interference applications. It operates at a nominal frequency of 7.3728 MHz with a CMOS output type. The device functions within a supply voltage range of 3.3V and maintains a frequency stability of ±50ppm. It supports an enable/disable control function and is rated for an operating temperature range of -40°C to +105°C. The component utilizes a 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Low EMI CMOS output signal generation
• Integrated enable and disable control functionality
• Compact 2.0mm x 1.6mm surface-mount footprint

Applications

• Digital clock distribution circuits
• Microcontroller system timing references
• Communication interface synchronization

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when ordering. Confirm that the 3.3V supply requirement aligns with the target circuit design. Ensure the ±50ppm stability specification meets the system's timing accuracy requirements. Check the operating temperature range limits against environmental conditions. Validate the 4-SMD package compatibility with PCB assembly processes.

Selection Notes

Select this component when a precise 7.3728 MHz reference is required in space-constrained designs. Consider the CMOS output level compatibility with downstream logic inputs. Evaluate the thermal performance within the specified -40°C to +105°C range. Compare the physical size against available board real estate. Assess the power consumption characteristics relative to battery-operated or low-power systems.

Part Context

This part belongs to the QTM216 series of low-profile oscillators from QST. The series offers various frequency options within a standardized 2.0mm x 1.6mm package. It serves as a compact alternative to larger through-hole or standard SMD oscillators. The product line emphasizes reduced electromagnetic interference for sensitive digital applications.

Replacement Considerations

Direct substitutes must match the 7.3728 MHz frequency, 3.3V supply, and 4-SMD package. Verify pinout compatibility and electrical specifications before substitution. Cross-reference with other manufacturers offering similar low-profile CMOS oscillators.
