The **MHO+15FGG-R** belongs to a specific category of high-precision electronic components, typically classified as a **TCXO (Temperature Compensated Crystal Oscillator)** or a high-stability clock source. These parts are essential in telecommunications, networking, and high-frequency RF applications where frequency stability is critical. --- ### 1. General Specifications The part number follows a specific manufacturer nomenclature (often associated with brands like MMD or Mercury). Below are the typical characteristics of this series: | Feature | Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (TCXO) | | **Package Type** | DIL-14 (Dual In-Line) or Half-Size DIL | | **Output Type** | HCMOS / TTL Compatible | | **Frequency Range** | Typically 1.000 MHz to 160.000 MHz | | **Supply Voltage** | Commonly 5.0V or 3.3V (indicated by suffix) | | **RoHS Status** | Compliant (indicated by the **-R** suffix) | --- ### 2. Breakdown of the Part Number While nomenclature varies slightly between manufacturers, the code usually breaks down as follows: 1. **MHO**: The series prefix, often designating a Metal Can, High-Stability Oscillator. 2. **+**: Often indicates a specific lead-free process or an enhanced version of the base model. 3. **15**: Typically refers to the **Supply Voltage**. In many naming conventions, "1" or "15" relates to a 5.0V operation, whereas "3" relates to 3.3V. 4. **FGG**: These characters usually define the **Frequency Stability** and **Operating Temperature Range**. * *Example:* "F" might represent ±25ppm stability, and "GG" might represent a temperature range of -40°C to +85°C. 5. **-R**: Indicates **RoHS Compliance** (Restriction of Hazardous Substances). --- ### 3. Key Electronic Functions * **Frequency Generation:** It provides a stable "heartbeat" for microprocessors and digital circuits. * **Temperature Compensation:** Unlike standard crystals, this component contains internal circuitry that adjusts the frequency based on ambient temperature to prevent "drift." * **Low Phase Jitter:** Designed for high-speed data transmission where timing errors must be minimized. --- ### 4. Typical Pin Configuration (DIL-14 Style) If this is a standard 14-pin DIP package (where only 4 pins are usually present): | Pin Number | Function | | :--- | :--- | | **Pin 1** | No Connect (NC) or Voltage Control (VCTCXO) | | **Pin 7** | Ground (Case) | | **Pin 8** | Output (Square Wave) | | **Pin 14** | Vcc (Supply Voltage) | --- ### 5. Common Applications * **Networking:** Base stations, routers, and switches. * **Test Equipment:** Oscilloscopes and frequency counters. * **Radio Communication:** Marine and aviation radio systems requiring high precision. ---
