Core Technical Specifications | Parameter | Specification | | :--- | :--- | | **Frequency** | 16.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Load Capacitance** | 15 pF (Built-in) | | **Operating Temperature** | -20°C to +80°C | | **Package Type** | SMD (3.2 x 1.3 mm) | | **Mounting Type** | Surface Mount (SMD) | --- ## 2. Electronic Characteristics & Features ### A. Built-in Capacitors One of the defining features of the `CSTCE` series is the **built-in load capacitance**. * **Circuit Simplification:** Unlike standard crystals that require two external ceramic capacitors, this device integrates them into the package. * **Space Saving:** It reduces the component count from three to one, making it ideal for high-density PCB designs. ### B. Resonant Mechanism It utilizes the mechanical vibration of a piezoelectric ceramic material (Lead Zirconate Titanate). When an oscillating electrical signal is applied, the material vibrates at its resonant frequency (16MHz), providing a stable clock reference. ### C. Frequency Stability While ceramic resonators are less stable than quartz crystals (±0.5% vs. ±0.005%), they are significantly more stable than internal RC oscillators. They are preferred for: * High-speed serial communication (UART). * USB peripherals. * General-purpose MCU clocking. --- ## 3. Pin Configuration and Internal Schematic The device features **three terminals**: 1. **Input (Pin 1):** Connection to the MCU's `OSC_IN`. 2. **Ground (Pin 2):** Common ground for the internal capacitors. 3. **Output (Pin 3):** Connection to the MCU's `OSC_OUT`. ```mermaid graph LR P1[Pin 1: Input] --- C1((Cap)) P3[Pin 3: Output] --- C2((Cap)) C1 --- P2[Pin 2: GND] C2 --- P2 ``` --- ## 4. Typical Applications * **Automotive Electronics:** Infotainment systems and body control modules. * **Consumer Electronics:** Remote controls, white goods (washers/dryers). * **PC Peripherals:** Keyboards, mice, and USB hubs.
