Key Technical Specifications Below is a breakdown of the primary electrical characteristics for this component: | Parameter | Specification | | :--- | :--- | | **Frequency** | 24.000 MHz | | **Supply Voltage (Vcc)** | +1.8V to +3.3V (Typical) | | **Output Type** | CMOS | | **Package Size** | 7.0 x 5.0 mm | | **Pin Count** | 4 Pins | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±25ppm to ±100ppm (Depending on specific suffix) | --- ### 2. Pin Configuration The device uses a standard 4-pad layout common to SMD (Surface Mount Device) oscillators: 1. **Pad 1: Standby (OE)** - Output Enable. High or Open allows the oscillator to function; Low puts it into standby mode. 2. **Pad 2: GND** - Connected to the system ground. 3. **Pad 3: Output** - The 24MHz clock signal output. 4. **Pad 4: Vcc** - Power supply input. --- ### 3. Core Features * **Tri-state Function:** Pad 1 allows the device to be disabled to save power, which is critical for battery-operated electronics. * **CMOS Drive:** Capable of driving standard CMOS logic loads directly without additional buffering. * **Reflow Solderable:** Designed for standard industrial SMD assembly processes. * **Low Jitter:** Engineered to provide a clean clock signal for sensitive digital circuits. --- ### 4. Common Applications This specific frequency (24MHz) and package type are frequently used in: * **Microcontrollers (MCUs):** Providing the external clock source for ARM Cortex chips. * **Communication Equipment:** Ethernet controllers, Wi-Fi modules, and Bluetooth SOCs. * **Consumer Electronics:** Digital cameras, printers, and portable media players. * **Industrial Automation:** PLCs and sensor interfaces. ---
