## Technical Overview of CSTCC3M58G56-R0 The **CSTCC3M58G56-R0** is a ceramic resonator manufactured by **Murata Manufacturing Co., Ltd.** It belongs to the CERALOCK® family, which are surface-mount (SMD) piezoelectric components used as frequency references in timing circuits. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 3.58 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% (-20°C to +80°C) | | **Internal Capacitance** | 47 pF (Built-in) | | **Package Type** | SMD (Surface Mount Device) | | **Termination Style** | 3-Terminal | | **Operating Temperature** | -20°C to +80°C | --- ### 2. Functional Characteristics #### Internal Load Capacitors Unlike traditional 2-pin crystals that require external load capacitors to oscillate, the **CSTCC** series features **built-in load capacitors**. This simplifies the PCB layout, reduces the component count, and saves space. #### Resonator Technology It utilizes the mechanical resonance of piezoelectric ceramics. While less precise than quartz crystals, ceramic resonators offer: * Faster start-up times. * Smaller physical footprints. * Significantly lower costs. --- ### 3. Pin Configuration & Application The device typically uses a **3-pin layout**: 1. **Input:** Connected to the oscillator circuit (e.g., MCU OSC_IN). 2. **Ground:** Connected to the system ground. 3. **Output:** Connected to the oscillator circuit (e.g., MCU OSC_OUT). #### Common Uses * **Microcontrollers:** Providing the clock signal for 8-bit or 16-bit MCUs. * **Consumer Electronics:** Remote controls, toys, and small household appliances. * **Legacy Video Equipment:** The 3.58 MHz frequency is historically significant as the **NTSC Color Burst frequency**, though in this SMD format, it is primarily used for general timing. --- ### 4.
