Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Nominal Frequency** | 10.000 MHz | | **Frequency Tolerance** | ±0.5% | | **Load Capacitance** | 33 pF (Built-in) | | **Operating Temperature** | -20°C to +80°C | | **Package / Case** | 3.2 x 1.3 mm (SMD Type) | | **Resonance Resistance** | 50 Ω (Maximum) | | **Aging** | ±0.3% (over 10 years) | --- ### 2. Physical Structure and Features * **Internal Capacitors:** This part is a "3-terminal" device. It includes internal load capacitors, which simplifies circuit design by eliminating the need for two external capacitors typically required by quartz crystals. * **Surface Mount Device (SMD):** The small footprint (3213 metric) allows for high-density mounting on Printed Circuit Boards (PCBs). * **Material:** It uses high-stability piezoelectric ceramics that convert electrical energy into mechanical vibration at a precise frequency. --- ### 3. Comparison: Ceramic Resonator vs. Quartz Crystal While both serve as frequency sources, the CSTCE10M0G55-R0 has distinct differences compared to a standard 10MHz crystal: | Feature | Ceramic Resonator (CSTCE) | Quartz Crystal | | :--- | :--- | :--- | | **Accuracy** | Moderate (±0.5%) | High (±0.001%) | | **Start-up Time** | Very Fast | Slower | | **Cost** | Generally lower | Higher | | **Size** | Smaller (built-in caps) | Larger (needs external caps) | --- ### 4. Common Applications * **Microcontrollers (MCUs):** Used as the primary clock source for 8-bit or 16-bit microcontrollers where extreme precision (like for RTC or high-speed RF) is not required. * **Consumer Electronics:** Remote controls, toys, and small appliances. * **Peripherals:** USB controllers and communication interfaces that can tolerate a ±0.5% frequency deviation. --- ### 5. Standard Circuit Diagram In a typical oscillator circuit (Colpitts or Pierce), the resonator is connected as follows: ```text MCU / IC +-----------+ | | | OSC_IN |----[ Pin 1: Input ] | | | | GND |----[ Pin 2: Ground ] | | | | OSC_OUT |----[ Pin 3: Output ] | | +-----------+ ``` ---
