Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Oscillation Frequency** | 8.000 MHz | | **Frequency Tolerance** | ±0.1% | | **Frequency Stability** | ±0.1% (Temperature dependent) | | **Load Capacitance** | 15 pF (Built-in) | | **Package Type** | SMD (Surface Mount Device) | | **Case Size** | 3.2 x 1.3 mm (EIA 1205) | | **Operating Temp Range** | -40°C to +125°C | --- ### 2. Functional Characteristics #### A. Built-in Load Capacitors Unlike standard quartz crystals that require external load capacitors ($C_1$ and $C_2$) to form an oscillation circuit, this resonator features **built-in capacitors**. * **Benefit:** Saves PCB space and reduces the external component count. * **Design:** It is a 3-pin device where the middle pin is connected to Ground (GND). #### B. Frequency Stability vs. Quartz * **Quartz Crystals:** Offer high precision (ppm level) but are more fragile and expensive. * **Ceramic Resonators:** Offer moderate precision (percentage level) but are much more resistant to mechanical shock/vibration and generally lower in cost. --- ### 3. Internal Pin Configuration | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | Input | Connected to MCU OSC_IN | | 2 | GND | Connected to System Ground | | 3 | Output | Connected to MCU OSC_OUT | --- ### 4. Application Areas Due to its small form factor and high temperature resistance, it is commonly found in: 1. **Automotive Electronics:** Powertrain control, safety systems, and body electronics. 2. **Consumer Electronics:** Home appliances, remote controls, and toys. 3. **Industrial Equipment:** Simple timing for logic circuits and interface controllers. --- ### 5. Part Number Breakdown (Murata Logic) * **CSTCE:** Series Name (SMD type with built-in caps). * **8M00:** Frequency (8.00 MHz). * **G:** Frequency Tolerance (±0.5% or better). * **15:** Load Capacitance value (15 pF). * **C99:** Individual specification code. * **R0:** Packaging (Plastic tape ø180mm reel).
