Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Oscillation Frequency** | 16.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Temperature Stability** | ±0.3% (-20°C to +80°C) | | **Package Type** | SMD (Surface Mount Device) | | **Built-in Capacitance** | 15 pF (Internal Load Capacitors) | | **Dimensions** | 3.2 x 1.3 x 0.7 mm | | **Operating Temp Range** | -20°C to +80°C | --- ### 2. Internal Components & Design The "V" in the part number indicates the **CSTCE_V** series. This specific part is a **three-terminal** device, which includes: 1. **Piezoelectric Element:** The core ceramic material that vibrates at 16MHz. 2. **Built-in Load Capacitors:** Unlike standard crystals that require two external capacitors to create an oscillation circuit, this resonator has them integrated inside the package. 3. **Terminals:** * Input/Output pins (Connect to MCU XTAL pins). * Ground pin (Center terminal). --- ### 3. Advantages of this Part * **Space Saving:** Because it has built-in capacitors, it reduces the PCB footprint and the Bill of Materials (BOM) count. * **High Reliability:** Ceramic resonators are generally more resistant to mechanical shock and vibration compared to quartz crystals. * **Fast Start-up:** They typically reach stable oscillation faster than quartz crystals. --- ### 4. Circuit Implementation When connecting this part to a Microcontroller (MCU), the wiring is simplified. ```cpp // Schematic Representation [MCU] [CSTCE16M3V53-R0] Pin: OSC_IN ------------------ Pin 1 (Input) Pin: VSS/GND ------------------ Pin 2 (Center Ground) Pin: OSC_OUT ------------------ Pin 3 (Output) ``` --- ### 5.
