Overview
The QTM216J-8.000MBJ-T is a surface-mount CMOS oscillator manufactured by QST, operating at a nominal frequency of 8 MHz with ±50 ppm stability. It utilizes a crystal base resonator and features a compact 4-SMD, No Lead package measuring 2.0mm x 1.6mm. The device supports a 3.3V supply voltage and includes an enable/disable function. It operates within a temperature range of -40°C to 105°C and has a maximum supply current of 22mA.
Feature Summary
- Integrated enable/disable control functionality for power management
- Compact 2.0mm x 1.6mm SMD footprint suitable for space-constrained designs
- CMOS output signal compatible with standard digital logic interfaces
Applications
- General-purpose clock generation in embedded systems
- Timing reference for microcontrollers and processors
- Digital signal processing circuits requiring stable 8 MHz input
Procurement Notes
Verify the specific suffix 'J' against the manufacturer's latest documentation to confirm pinout configuration and enable/disable polarity. Ensure the selected variant matches the required 3.3V supply rail and that the 22mA maximum current consumption aligns with the system's power budget constraints.
Selection Notes
Select this component when a low-profile 2016 package is required for 8 MHz timing applications. Confirm compatibility with 3.3V logic levels and verify that the ±50 ppm frequency stability meets the target circuit's tolerance requirements. Consider the enable/disable feature if dynamic power saving is necessary.
Part Context
This part belongs to the QTM216 series of low-profile oscillators from QST. The series offers various frequencies and packages, with the J suffix typically indicating specific packaging or pinout variations. It serves as a direct replacement for legacy through-hole crystals in modern surface-mount assemblies.
Replacement Considerations
Check datasheets for alternative 8 MHz oscillators in 2016 packages from other manufacturers. Verify that substitute parts match the 3.3V supply, CMOS output type, and ±50 ppm stability. Ensure physical dimensions and pin assignments are identical to avoid PCB redesign.
