QTM216J-8.192MBJ-T

Overview

The QTM216J-8.192MBJ-T is a standard CMOS crystal oscillator manufactured by QST Products, designed for surface-mount applications. It operates at a nominal frequency of 8.192 MHz with a frequency stability of ±50 ppm. The device requires a 3.3V supply voltage and features an enable/disable function to control power consumption. It utilizes a basic crystal resonator and is housed in a compact 4-SMD, no-lead package measuring 2.0mm x 1.6mm. The component supports an operating temperature range of -40°C to 105°C and draws a maximum supply current of 10 mA.

Feature Summary

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

Applications

• Embedded systems requiring precise clock signals
• Industrial control equipment
• Consumer electronics with space constraints

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 3.3V supply requirement aligns with the target system's voltage rails. Ensure the ±50 ppm stability meets the application's timing tolerance requirements. Check the lead-free status if environmental compliance is mandatory for the end product.

Selection Notes

Select this model when a small form factor is critical due to its 2.0x1.6mm dimensions. Choose this part if the design requires active power-down capabilities via the enable pin. Consider the -40°C to 105°C range for industrial or automotive-grade environments where standard commercial ranges are insufficient.

Part Context

This component belongs to the QTM216 series of low-profile oscillators from QST. The series is characterized by its miniature size and CMOS compatibility, making it suitable for modern PCB layouts with high component density. It serves as a direct replacement for larger through-hole or standard SMD oscillators in space-constrained designs.

Replacement Considerations

Direct substitutes must match the 8.192 MHz frequency, 3.3V supply, and 4-SMD package. Verify that alternative parts support the same ±50 ppm stability and enable/disable logic levels.
