QTT216-32.000MBN-T

Overview

The QTT216-32.000MBN-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST. It operates at a nominal frequency of 32 MHz with a frequency stability of ±2 ppm over an operating temperature range of -30°C to +85°C. The device utilizes a CMOS output format and requires a supply voltage of 3.3 V. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.00 mm x 1.60 mm.

Feature Summary

• Temperature compensation ensures stable frequency performance across industrial temperature ranges
• Compact surface-mount footprint suitable for space-constrained designs
• CMOS output interface compatible with standard digital logic circuits

Applications

• Wireless communication modules requiring precise clocking
• Portable electronic devices with limited board space
• Industrial control systems operating in variable temperatures

Procurement Notes

Verify the specific suffix 'MBN' against official QST documentation to confirm the exact output type and voltage requirements. Ensure the ordering quantity aligns with distributor packaging standards. Confirm that the ±2 ppm stability specification meets the system timing budget before finalizing procurement.

Selection Notes

Select this component when a 32 MHz reference signal is required with high thermal stability. Compare the ±2 ppm stability against alternatives if tighter tolerance is needed. Verify the 3.3 V supply requirement matches the target system power rails. Consider the 4-SMD package size for PCB layout constraints.

Part Context

This part belongs to the QTT216 series of quartz-clipped sine TCXOs from QST. The series offers various frequencies and stability options. The MBN suffix typically denotes specific electrical characteristics such as output type and voltage, distinguishing it from other variants like MDN or MBG within the same family.

Replacement Considerations

Direct substitutes include QTT216-32.000MDN-T, which shares the same package but may differ in supply voltage specifications. Cross-reference with QTT216-32.000MBG-T for alternative packaging or stability options. Always verify pin compatibility and electrical parameters before substitution.
