Technical Specifications The part number follows a specific nomenclature that defines its electrical and physical properties: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | Active timing component | | **Package Size** | 7.0 x 5.0 mm | Standard 4-pad SMD (Surface Mount Device) | | **Output Logic** | CMOS / TTL | Compatible with standard digital logic levels | | **Supply Voltage** | 3.3V or 5.0V | Usually specified by the "24" or "S" code in the series | | **Frequency Stability** | ±25ppm to ±100ppm | Dependent on the specific suffix (J-R) | | **Operating Temp** | -40°C to +85°C | Industrial grade (standard for the FBJ series) | --- ### 2. Key Internal Components An oscillator like the M7S24FBJ-R is an "active" component, meaning it contains more than just a quartz crystal. Its internal architecture includes: 1. **Quartz Crystal Blank:** The heart of the unit, precision-cut to vibrate at a specific fundamental or overtone frequency. 2. **Oscillator IC:** An integrated circuit that provides the gain necessary to start and maintain oscillations. 3. **Load Capacitors:** Integrated internally to ensure the crystal resonates at the correct frequency without needing external tuning. 4. **Tri-state Buffer:** Allows the output to be placed in a high-impedance state (Enable/Disable function), useful for power saving and testing. --- ### 3. Pin Configuration (Typical 4-Pad SMD) | Pin # | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable control or No Connection | | **2** | GND | Circuit Ground | | **3** | Output | Frequency signal output | | **4** | Vdd | Power supply voltage | --- ### 4. Typical Applications * **Networking:** Ethernet switches, routers, and high-speed data transmission. * **Computing:** Clock generation for microprocessors and FPGAs. * **Industrial:** Embedded systems requiring stable timing over a wide temperature range. * **Consumer Electronics:** High-definition video equipment and digital audio interfaces.
