Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Oscillation Frequency** | 35.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Temperature Stability** | ±0.3% (varies by operating range) | | **Built-in Load Capacitance** | 5 pF | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | 2.0 x 1.3 mm (Small Form Factor) | | **Operating Temperature** | -20°C to +80°C (Standard Industrial) | --- ### 2. Functional Components This device is more than just a raw ceramic element; it is a composite component designed for easy integration: * **Ceramic Resonator Element:** The core uses the mechanical vibration of piezoelectric ceramics to create a stable frequency. * **Built-in Load Capacitors:** Unlike traditional crystals that require external capacitors (C1 and C2) to stabilize the oscillation loop, this part has them integrated internally. This saves PCB space and reduces the Bill of Materials (BOM). * **3-Terminal Design:** It typically features three pads: Input, Ground, and Output. --- ### 3. Comparison: Ceramic Resonator vs. Quartz Crystal The CSTCG35M0V53-R0 is often chosen over quartz crystals for specific reasons: | Feature | Ceramic Resonator (CSTCG) | Quartz Crystal | | :--- | :--- | :--- | | **Cost** | Lower | Higher | | **Size** | Generally smaller/thinner | Larger | | **Start-up Time** | Very Fast | Slower | | **Frequency Accuracy** | Moderate (±0.5%) | High (ppm level) | | **Stability** | Good | Excellent | --- ### 4. Typical Applications Due to its high frequency (35 MHz) and small footprint, it is commonly found in: 1. **USB Peripherals:** Providing the clock for high-speed data transfer. 2. **Microcontrollers:** Serving as the main system clock for MCUs where extreme precision (like a real-time clock) isn't mandatory. 3. **Consumer Electronics:** Used in cameras, portable audio players, and small household appliances. --- ### 5. Recommended Circuit Layout To ensure the best performance, the resonator should be placed as close to the Microcontroller (MCU) as possible to minimize parasitic capacitance and EMI. ```c // Typical Connection Diagram [ MCU_OSC_IN ] <-----> [ Terminal 1: Input ] [ GND ] <-----> [ Terminal 2: Ground ] [ MCU_OSC_OUT] <-----> [ Terminal 3: Output ] ```
