QTT216-32.000MDN-T

Overview

The QTT216-32.000MDN-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST, operating at a nominal frequency of 32 MHz. It utilizes a quartz base resonator and features a CMOS output format suitable for digital logic integration. The device operates on a 1.8V supply voltage with a maximum current consumption of 2 mA. Frequency stability is specified at 2 ppm. The component is housed in a compact 4-SMD, No Lead package, designed for surface-mount assembly.

Feature Summary

• Integrates a quartz base resonator within a temperature-compensated design to maintain frequency accuracy across varying thermal conditions.
• Delivers a CMOS output signal compatible with standard digital circuitry interfaces.
• Operates efficiently on a low 1.8V power supply with minimal current draw.

Applications

• Precision timing circuits requiring stable clock signals
• Portable electronic devices utilizing low-voltage operation
• Communication modules needing accurate frequency references

Procurement Notes

Verify the specific manufacturer designation as sources list this part under both QST and TXC Corporation branding. Confirm the supply voltage requirement matches your system design, as variants exist for different voltages. Ensure the 4-SMD no-lead package footprint aligns with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a 32 MHz reference with 2 ppm stability is required in a small form factor. The CMOS output simplifies interface design compared to sine wave outputs. Verify that the 1.8V operating voltage is compatible with the target application's power domain, as other series members support different voltages.

Part Context

This model belongs to the QTT216 series of TCXOs, characterized by a 2.0x1.6 mm footprint. It represents a specialized variant optimized for low-voltage applications, distinct from higher-voltage counterparts like the 3.3V MBG-T version. The series focuses on balancing size, power consumption, and frequency stability for embedded systems.

Replacement Considerations

QTT216-32.000MBG-T offers similar specifications but operates at 3.3V instead of 1.8V. QTT216-32.000MBN-T is another variant potentially differing in voltage or output type. Verify pin compatibility and voltage levels before substituting.
