The **CSTCC3M52G53Z-R0** is a specific type of electronic component known as a **Ceramic Resonator** with built-in load capacitors, manufactured by Murata Electronics. It belongs to the CERALOCK® family. --- ### 1. General Specifications This component is primarily used as a clock source for microprocessors and microcontrollers. | Feature | Specification | | :--- | :--- | | **Frequency** | 3.52 MHz | | **Frequency Tolerance** | ±0.5% | | **Resonance Impedance** | 50 Ω (Max) | | **Built-in Capacitance** | 15 pF (Internal load capacitors) | | **Temperature Range** | -20°C to +80°C | | **Package Type** | SMD (Surface Mount Device) | | **Mounting Type** | Tape & Reel (indicated by "-R0") | --- ### 2. Technical Breakdown * **Ceramic Resonator Technology:** Unlike Quartz crystals which use silicon dioxide, ceramic resonators utilize the mechanical resonance of piezoelectric ceramics (usually Lead Zirconate Titanate). * **Integrated Capacitors:** The "Built-in" feature is crucial. In a standard Pierce oscillator circuit, you usually need two external capacitors to ground. This part includes them internally, saving PCB space and reducing component count. * **Accuracy:** It is more accurate than a standard RC (Resistor-Capacitor) oscillator but less precise than a Quartz Crystal. It is ideal for applications where timing is important but not mission-critical (like basic USB or high-speed serial comms). --- ### 3. Part Number Decoder Murata part numbers follow a specific nomenclature: | Code Segment | Meaning | | :--- | :--- | | **CSTCC** | Series name (SMD type with built-in capacitance) | | **3M52** | Frequency (3.52 MHz) | | **G** | Frequency tolerance (G = ±0.5%) | | **53** | Load capacitance code (53 = 15pF) | | **Z** | Individual specification code | | **-R0** | Packaging (Plastic tape ø180mm reel) | --- ### 4. Circuit Implementation To use this part, you connect it to the `OSC_IN` and `OSC_OUT` pins of a microcontroller. Because the capacitors are internal, the center pin is connected to **Ground (GND)**. ```c // Typical Connection Diagram [MCU OSC_IN] ---- [Pin 1: Resonator] [MCU GND] ---- [Pin 2: Common/GND] [MCU OSC_OUT] ---- [Pin 3: Resonator] ``` ---
