Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 3.58 MHz | | **Frequency Tolerance** | ±0.5% | | **Frequency Stability** | ±0.3% (over temperature range) | | **Operating Temperature** | -20°C to +80°C | | **Load Capacitance** | 15 pF (Built-in) | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 3-SMD, Non-Standard | --- ### 2. Physical Structure and Components 1. **Ceramic Element:** The heart of the component is a piezoelectric ceramic disk that vibrates at a specific frequency (3.58 MHz) when an electrical signal is applied. 2. **Built-in Capacitors:** This specific model is a **3-terminal device**. It includes internal load capacitors, eliminating the need for two external capacitors typically required in an oscillation circuit. 3. **Encapsulation:** It is housed in a resin-molded or ceramic package designed to withstand reflow soldering processes. --- ### 3. Functional Role in Circuits The CSTCC3M58G53-R0 acts as the "heartbeat" for microcontrollers and microprocessors. * **Oscillation:** It is usually connected to the `XTAL1` and `XTAL2` pins of a microcontroller. * **Clock Generation:** It provides a stable clock signal used to sequence instructions and synchronize peripheral communication. * **Space Saving:** Because it has built-in capacitors, it reduces the Bill of Materials (BOM) and saves PCB real estate compared to a quartz crystal. --- ### 4. Comparison: Ceramic Resonator vs. Quartz Crystal | Feature | Ceramic Resonator (CSTCC) | Quartz Crystal | | :--- | :--- | :--- | | **Cost** | Lower | Higher | | **Accuracy** | Moderate (±0.5%) | High (±0.001%) | | **Start-up Time** | Very Fast | Slower | | **Size** | Small with built-in caps | Varies, usually larger | --- ### 5. Common Applications * **Microcontroller Clocks:** For 8-bit or 16-bit MCUs where extreme precision (like for high-speed USB) isn't required. * **Consumer Electronics:** Remote controls, white goods (washers/dryers), and toys. * **Legacy Video Equipment:** 3.58 MHz is the standard NTSC color subcarrier frequency, making this part common in older video processing hardware.
