The **CSTCE13M0G52-R0** is a high-precision ceramic resonator produced by **Murata Manufacturing**. It is part of the CERALOCK® family, designed to provide a stable clock signal for microcontrollers and other digital circuits. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Nominal Frequency** | 13.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Load Capacitance** | 10 pF (Built-in) | | **Resonant Resistance** | 50 Ω (Max) | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | 3.2 x 1.3 mm (Small Cap Chip) | --- ### 2. Key Internal Components The CSTCE series is unique because it integrates several components into a single tiny package: 1. **Ceramic Element:** The core piezoelectric element that vibrates at the specific 13MHz frequency when an electrical signal is applied. 2. **Built-in Load Capacitors:** Unlike traditional quartz crystals that require two external capacitors (C1 and C2) to complete the oscillation circuit, this part has them built-in. 3. **Electrode Terminals:** Three terminals (Input, Ground, Output) allowing for a compact PCB layout and reduced part count. --- ### 3. Circuit Comparison: Crystal vs. Resonator Using the CSTCE13M0G52-R0 simplifies the design process significantly. #### Traditional Crystal Setup ```text MCU_XTAL1 ----| [Crystal] |---- MCU_XTAL2 | | [Cap] [Cap] | | (GND) (GND) ``` #### CSTCE13M0G52-R0 Setup ```text MCU_XTAL1 ---- [Pin 1] (Input) (GND) ---- [Pin 2] (Ground) MCU_XTAL2 ---- [Pin 3] (Output) ``` --- ### 4. Advantages and Use Cases * **Space Saving:** Because it eliminates the need for external capacitors, it saves significant board real estate. * **Cost-Effective:** Generally cheaper than quartz crystals of the same frequency. * **Durability:** High resistance to mechanical shock and vibration compared to glass-sealed crystals. * **Common Applications:** * USB peripherals. * Home appliances (washing machines, microwave ovens). * Microcontroller (MCU) clocking where extreme sub-ppm precision is not required.
