Overview
The QTM216-20.000MDE-T is a CMOS standard oscillator manufactured by QST, operating at a frequency of 20 MHz. It utilizes a 4-SMD, No Lead surface-mount package with dimensions of 2.0mm x 1.6mm and a height of 0.75mm. The device supports supply voltages of 1.8V, 2.5V, and 3.3V, featuring an enable/disable control function. Frequency stability is rated at ±50ppm over the operating temperature range of -40°C to +85°C. Maximum supply current is specified at 10mA. The output characteristics include a load capacitance of 15pF, rise/fall times of maximum 6ns, and duty cycle within 45% to 55%.
Feature Summary
- Integrated enable/disable functionality for power management optimization.
- Low electromagnetic interference design suitable for compact applications.
- Wide voltage compatibility supporting multiple logic levels.
Applications
- Smartwatch and wearable device clock sources
- System-in-Package (SiP) modules
- Bluetooth Low Energy (BLE) communication interfaces
Procurement Notes
Verify the specific suffix codes against official QST documentation to confirm exact electrical parameters, including frequency tolerance, temperature range, and output drive strength. Ensure the selected variant matches the required supply voltage and enable pin configuration for the target application circuit design.
Selection Notes
Select this component when space constraints require a 2016 footprint with minimal profile height. Consider the ±50ppm stability rating for general-purpose timing needs. Evaluate the 10mA current consumption against battery life requirements for portable electronics. Confirm that the CMOS output swing aligns with the input thresholds of the connected microcontroller or processor.
Part Context
This part belongs to the QTM216 series of low-profile CMOS oscillators designed for space-sensitive consumer and industrial electronics. The series offers various frequency options within a standardized 2.0x1.6mm ceramic package, providing a consistent mechanical solution for high-volume manufacturing and automated assembly processes.
Replacement Considerations
Direct substitutes may include other 2016 footprint CMOS oscillators from manufacturers such as TXC or Epson, provided they match the 20MHz frequency, 3.3V/1.8V supply, and ±50ppm stability specifications. Verify pinout compatibility and thermal performance before substitution.
