QTM216E-25.000MDM-T

Overview

The QTM216E-25.000MDM-T is a low EMI CMOS quartz oscillator manufactured by QST, operating at a nominal frequency of 25 MHz. It features a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 x 0.76 mm. The device supports a supply voltage of 1.8 V and offers a frequency stability of ±50 ppm across an operating temperature range of -40°C to 125°C. Maximum supply current is specified at 10 mA. A key functional parameter is the RMS phase jitter, which remains ≤1 ps in the disable phase modulation mode, ensuring high clock precision for video transmission applications.

• Mobile phone and wearable device timing circuits
• Embedded communication interfaces requiring low jitter
• MIPI and LVDS display driver clocks

Procurement Notes

Verify the specific suffix 'MDM' against official QST documentation to confirm the exact voltage and temperature grade, as ordering codes may vary. Ensure the selected variant matches the required 1.8V supply and industrial temperature range for your design. Cross-reference the datasheet for pin configuration and enable/disable control logic to guarantee hardware compatibility before finalizing the purchase order.

Selection Notes

Select this component when strict EMI limits must be met without adding passive filtering components. The integrated phase modulation feature allows software-controlled spectrum spreading, simplifying PCB layout. Choose this part for applications requiring a balance between ultra-small footprint and high-frequency stability in harsh thermal environments.
