QTM216-27.000MBE-T

Overview

The QTM216-27.000MBE-T is a standard CMOS oscillator manufactured by QST, operating at a frequency of 27 MHz. It utilizes a crystal resonator and supports a supply voltage of 3.3V with enable/disable functionality. The device features a frequency stability of ±50ppm and operates within a temperature range of -40°C to 85°C. It consumes a maximum supply current of 10mA and is housed in a compact 4-SMD, No Lead package measuring 2.0x1.6 mm.

Feature Summary

• Integrated CMOS output stage designed for low electromagnetic interference (EMI) applications.
• Includes hardware enable and disable control pin for power management optimization.
• Compact surface-mount footprint suitable for high-density PCB layouts.

Applications

• Standard clock generation for digital logic circuits
• Timing reference for microprocessors and microcontrollers
• Data communication interface synchronization

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 3.3V supply voltage aligns with the target system's power rails. Ensure the ±50ppm frequency stability meets the timing requirements of the connected components. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a precise 27 MHz reference is required for CMOS-compatible interfaces. Consider the 4-SMD package size for space-constrained designs. Evaluate the ±50ppm stability against the system's jitter tolerance. Verify that the -40°C to 85°C industrial temperature range covers the operational environment.

Part Context

This part belongs to the QTM216 series of low-profile oscillators from QST. The series offers various frequencies and packages, providing designers with standardized timing solutions. The 2.0x1.6 mm form factor represents one of the smallest options in the lineup, facilitating miniaturization in modern electronic devices.

Replacement Considerations

Direct substitutes include other QTM216 variants with different frequencies or the QTM216E series for enhanced EMI performance. Cross-manufacturer replacements require matching the 2.0x1.6mm footprint, 3.3V supply, and CMOS output characteristics.
