The **MHO+65FBG-R** is a specific part number typically associated with high-precision **Crystal Oscillators** (XO), often manufactured by companies like MtronPTI. These components are critical for providing a stable clock signal in electronic circuits. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics. Below is a breakdown of the typical specifications for this series: | Feature | Specification | | :--- | :--- | | **Component Type** | Quartz Crystal Oscillator (Fixed) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | CMOS / TTL Compatible | | **Operating Voltage** | Typically 5.0V or 3.3V (Model dependent) | | **Frequency Stability** | ±25ppm to ±100ppm (Commonly ±50ppm) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the "R" suffix) | --- ### 2. Pin Configuration Since this is a standard 14-pin DIP package (though usually only 4 pins are physically present), the pinout generally follows this industry standard: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or E/D | No Connection or Tri-state Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | Positive Power Supply | --- ### 3. Key Electronic Characteristics * **High Stability:** The "MHO" series is known for maintaining a consistent frequency even when subjected to temperature fluctuations. * **Hermetic Sealing:** The metal "Full Size" DIP can is hermetically sealed to protect the internal quartz crystal from moisture and atmospheric contaminants, ensuring long-term reliability. * **Through-Hole Mounting:** Unlike modern SMD (Surface Mount Device) oscillators, the "FBG" designation usually refers to a through-hole configuration, making it ideal for robust industrial equipment or older PCB designs. ### 4. Typical Applications These oscillators are used in timing circuits where a precise frequency reference is required: 1. **Industrial Controllers:** PLC units and automation hardware. 2. **Communication Equipment:** Modems, routers, and base stations. 3. **Embedded Systems:** Microcontrollers requiring an external high-accuracy clock source. 4. **Legacy Hardware:** Repair and maintenance of older computing systems. ---
