The **CSTCC3M60G56-R0** is a specific model of a **Ceramic Resonator** manufactured by Murata Manufacturing. It belongs to the CERALOCK® family, designed to provide a stable clock signal for microprocessors and other digital circuits. --- ## 1. Component Overview The CSTCC series is a surface-mount (SMT) ceramic resonator that includes **built-in load capacitors**. This integration simplifies circuit design by eliminating the need for external capacitors, saving PCB space. ### Key Specifications | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 3.60 MHz | | **Frequency Tolerance** | ±0.5% | | **Operating Temperature** | -20°C to +80°C | | **Built-in Capacitance** | 47 pF (nominal) | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | 7.2 x 3.0 mm | --- ## 2. Technical Breakdown ### A. The Piezoelectric Effect Like a quartz crystal, a ceramic resonator utilizes the mechanical resonance of piezoelectric ceramics (usually Lead Zirconate Titanate). When an electrical signal is applied, the ceramic vibrates; these vibrations are converted back into a stable electrical frequency. ### B. Internal Load Capacitors The "G" in the part number indicates the presence of internal capacitors. In a standard Pierce oscillator circuit, you would normally need two external capacitors (C1 and C2). In this part: - The center terminal is grounded. - The two outer terminals connect to the Input/Output of the oscillator inverter. - The internal capacitors are already tuned for the 3.60 MHz frequency. --- ## 3. Pinout and Circuit Application The device typically has three terminals: 1. **Terminal 1:** Input (Connected to Oscillator In) 2. **Terminal 2:** Ground (GND) 3. **Terminal 3:** Output (Connected to Oscillator Out) ### Typical Circuit Diagram ```text [Microcontroller] / \ XTAL1/OSC_IN XTAL2/OSC_OUT | | ______|______________|______ | 1 3 | | [ RESONATOR ] | | 2 | |_____________|______________| | Ground ``` --- ## 4. Comparison: Resonator vs. Crystal | Feature | Ceramic Resonator (CSTCC) | Quartz Crystal | | :--- | :--- | :--- | | **Accuracy** | Moderate (±0.5%) | High (±0.001%) | | **Start-up Time** | Very Fast | Slower | | **Cost** | Low | Higher | | **Size** | Small (Integrated Caps) | Larger (External Caps needed) | | **Common Use** | Remote controls, toys, appliances | PCs, Watches, High-speed Comms | --- ## 5.
