QTM216J-20.000MBJ-T

Overview

The QTM216J-20.000MBJ-T is a surface-mount crystal oscillator manufactured by QST, operating at a nominal frequency of 20 MHz with CMOS output. It functions within a supply voltage range of 3.3V and maintains a frequency stability of ±50 ppm. The device supports an operating temperature range from -40°C to 105°C and draws a maximum supply current of 22 mA. Housed in a compact 4-SMD, no-lead package measuring 2.0mm x 1.6mm, it is designed for applications requiring reliable clock signals in industrial environments.

Feature Summary

• Integrates a quartz crystal resonator within a compact SMD package for stable clock generation
• Features CMOS output interface compatible with standard digital logic circuits
• Supports wide industrial operating temperatures up to 105°C for robust performance

Applications

• Industrial control systems requiring precise timing
• Embedded devices needing stable clock sources
• Automotive electronics compliant with AEC-Q100 standards

Procurement Notes

Verify the specific suffix 'J' confirms the required temperature grade and automotive qualification status against project specifications. Ensure the 3.3V supply requirement aligns with the target system's power rails. Confirm the 20 MHz frequency matches the design requirements before ordering. Check packaging options such as tape and reel availability for automated assembly processes.

Selection Notes

Select this component when a 20 MHz clock signal is required with ±50 ppm stability in industrial or automotive contexts. Consider the 22 mA current consumption for power budget calculations. The 2.0x1.6 mm footprint suits space-constrained designs. Verify compatibility with the host circuit's input impedance and load capacitance requirements.

Part Context

This part belongs to the QTM216 series of low-profile oscillators from QST. The series offers various frequencies and supply voltages in a standardized 2016 package. The 'J' suffix typically denotes specific environmental ratings or automotive qualification, distinguishing it from commercial-grade variants in the same physical form factor.

Replacement Considerations

Direct substitutes include other 20 MHz, 3.3V, ±50 ppm CMOS oscillators in 2016 packages from manufacturers like TXC. Ensure pinout compatibility and electrical parameter equivalence. Verify that any replacement meets the same temperature and reliability standards.
