The **CSTCE10M0G52Z-R0** is a specific surface-mount ceramic resonator manufactured by **Murata Electronics**. It belongs to the **CERALOCK®** family, which are high-precision frequency control components used similarly to quartz crystals but with a smaller footprint and built-in load capacitors. --- ## 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 10.0 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% | | **Operating Temperature** | -20°C to +80°C | | **Internal Capacitance** | 10 pF (Built-in) | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | 3.2 x 1.3 mm (EIA 1205) | | **Packaging** | Tape & Reel (R0 suffix) | --- ## 2. Structural Features ### Built-in Load Capacitors Unlike traditional crystals that require two external capacitors to create an oscillation circuit, this part features **integrated load capacitors**. * **Pins 1 & 3:** Input/Output. * **Pin 2:** Ground (GND). * **Benefit:** Reduces the Bill of Materials (BOM) and saves PCB real estate. ### Ceramic Technology It uses the mechanical resonance of piezoelectric ceramics. While less precise than quartz (which offers ppm-level stability), ceramic resonators are: * Faster to start up. * More resistant to mechanical shock and vibration. * Significantly cheaper than quartz crystals. --- ## 3. Circuit Application In a typical microcontroller (MCU) application, the CSTCE10M0G52Z-R0 is connected to the `OSC_IN` and `OSC_OUT` pins. ```c // Example: Concept of frequency usage in firmware #define F_CPU 10000000UL // 10 MHz clock defined for timing ``` ### Typical Schematic Connection 1. **Pin 1 (Input):** Connected to MCU XTAL1. 2. **Pin 2 (GND):** Connected to System Ground. 3. **Pin 3 (Output):** Connected to MCU XTAL2. --- ## 4. Common Use Cases * **Microprocessor Clocks:** Providing the base clock for 8-bit or 16-bit MCUs. * **Consumer Electronics:** Remote controls, white goods (washers/dryers), and toys. * **Peripherals:** USB high-speed controllers or communication interfaces where ±0.5% tolerance is acceptable. ---
