Key Technical Specifications Below are the typical electronic characteristics associated with this part number series: | Parameter | Specification (Typical) | | :--- | :--- | | **Type** | MEMS Oscillator | | **Output Frequency** | Factory Programmed (Range: 1MHz to 150MHz) | | **Supply Voltage** | 1.8V, 2.5V, 2.8V, or 3.3V | | **Output Type** | LVCMOS / HCMOS | | **Frequency Stability** | ±20 ppm to ±50 ppm | | **Operating Temperature** | -40°C to +85°C (Extended Industrial) | | **Package Size** | 2.0 x 1.6 mm or 3.2 x 2.5 mm (SMD) | --- ### 2. Functional Electronic Sections The internal architecture of the M3E14ZPA-R consists of several integrated circuits working in tandem: #### A. MEMS Resonator The core "heart" of the part. Unlike traditional quartz crystals, this is a tiny silicon structure that vibrates at a high frequency when electrically stimulated. It is vacuum-sealed to ensure long-term reliability and resistance to mechanical shock. #### B. Fractional-N PLL (Phase-Locked Loop) This electronic block takes the raw frequency from the MEMS resonator and multiplies or divides it to achieve the specific output frequency required by the user. #### C. Temperature Compensation Circuitry Since silicon properties change with temperature, an internal sensor and compensation logic adjust the frequency in real-time to maintain high stability across the entire operating range. #### D. Output Driver The final stage is an LVCMOS driver designed to interface with microcontrollers (MCUs) or FPGAs. It manages the "Rise Time" and "Fall Time" of the digital clock signal to minimize Electromagnetic Interference (EMI). --- ### 3. Application Use Cases * **Automotive Systems:** ADAS sensors and infotainment units where vibration resistance is critical. * **IoT Devices:** Battery-powered sensors that require low current consumption during sleep modes. * **Industrial Automation:** PLCs and high-speed communication modules. --- ### 4.
