QT216G-27.000MEAB-T

Overview

The QT216G-27.000MEAB-T is a quartz crystal oscillator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 27 MHz with a load capacitance of 6 pF. The component features a compact 4-SMD, no-lead package measuring 2.0 x 1.6 mm. Frequency stability is specified at ±10 ppm over the operating temperature range, with an initial tolerance of ±30 ppm at 25°C. This TCXO variant utilizes a clipped sine wave output format and is powered by a 3.3 V supply, ensuring reliable performance in precision timing circuits.

Feature Summary

• Compact 2.0x1.6 mm SMD footprint for space-constrained designs
• High frequency stability of ±10 ppm across operating temperatures
• Clipped sine wave output suitable for digital logic interfaces
• Integrated temperature compensation for consistent performance

Applications

• Embedded communication systems requiring precise clocking
• Mobile device baseband processing units
• IoT sensor nodes with strict power and size constraints
• Wireless module synchronization circuits

Procurement Notes

Verify the specific suffix 'MEAB' against the manufacturer's current datasheet to confirm exact tolerance and packaging specifications. Ensure compatibility with 3.3V logic levels and check for any recent design changes or obsolescence notices from QST before finalizing procurement orders.

Selection Notes

Select this component when a small form factor and high stability are required for 27 MHz applications. Compare against standard crystals if temperature compensation is not needed. Verify that the clipped sine wave output matches the input requirements of the downstream circuitry to ensure signal integrity.

Part Context

This part belongs to the QT216G series of temperature-compensated crystal oscillators (TCXOs) from QST. These devices are engineered for high-performance timing applications where size and stability are critical. The series offers various frequency options within the same compact package, facilitating standardized design processes across different product lines.

Replacement Considerations

Direct substitutes include other 27 MHz TCXOs in 2.0x1.6 mm packages with similar ±10 ppm stability. Check pinout compatibility and voltage requirements. Cross-reference with TXC Corporation equivalents if available, ensuring identical electrical parameters and mechanical dimensions.
