QTM216J-16.000MDJ-T

Overview

The QTM216J-16.000MDJ-T is a surface-mount CMOS oscillator manufactured by QST, operating at a frequency of 16 MHz. It features a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm and a height of 0.75mm. The device supports a supply voltage of 1.8V and includes an enable/disable control function. Frequency stability is specified at ±50ppm over the operating temperature range of -40°C to +85°C. Maximum supply current is 10mA, and it utilizes a crystal as the basic resonator.

Feature Summary

• Compact 2016 SMD ceramic seam-welded package for space-constrained designs
• Integrated enable/disable pin for power management in low-power applications
• CMOS output with low electromagnetic interference characteristics
• Industrial temperature rating suitable for demanding environments

Applications

• Smartwatch and wearable device clock sources
• System-in-Package (SiP) modules
• Bluetooth Low Energy (BLE) communication interfaces
• Portable consumer electronics requiring low profile components

Procurement Notes

Verify that the specific suffix 'DJ' corresponds to the required voltage and stability configuration for your design. Confirm the package orientation and pinout against the official datasheet before PCB layout finalization. Ensure the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment.

Selection Notes

Select this component when a sub-1mm height and minimal footprint are critical constraints. It is appropriate for designs requiring a single 1.8V supply without external LDOs. Consider the ±50ppm total stability specification for timing accuracy requirements. Evaluate the enable/disable feature necessity for power budget optimization in battery-operated devices.

Part Context

This part belongs to the QTM216 series of low EMI CMOS oscillators from QST. The series is characterized by its small 2016 package size and wide frequency coverage options. It targets modern portable electronics where board space and power consumption are primary design drivers. The J suffix typically denotes specific stability or voltage variants within the product line.

Replacement Considerations

Direct substitutes include other 2016 package CMOS oscillators from manufacturers such as TXC or Epson, provided they match the 16MHz frequency, 1.8V supply, and ±50ppm stability. Verify pin compatibility and thermal characteristics before swapping. Generic family replacements may differ in jitter performance or enable logic levels.
