The **MHO+14TGG-R** is a specific part number typically associated with a **High-Frequency Crystal Oscillator**. These components are essential for providing a stable clock signal in digital circuits, telecommunications, and computing hardware. Below is a breakdown of the electronic specifications and characteristics based on the standard naming conventions for this series (often manufactured by companies like **MtronPTI**). --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Mounting Style** | Through-Hole | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown While specific manufacturer prefixes can vary slightly, the nomenclature generally follows this logic: * **MHO:** Series designation (Metal Hermetic Oscillator). * **+:** Often indicates a specific voltage or lead-free process. * **14:** Refers to the "14-pin DIP" footprint (though only 4 pins are usually active). * **T:** Temperature Stability/Range code (Typically -40°C to +85°C for industrial grade). * **G:** Symmetry/Duty Cycle specification (e.g., 45/55%). * **G:** Voltage Supply code (Commonly 5.0V or 3.3V depending on the sub-series). * **-R:** RoHS Compliant (Lead-free). --- ### 3. Pin Configuration (Internal Connectivity) Even though the package has a 14-pin footprint, only 4 pins are electrically connected to the internal circuit: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-State | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground / Case Ground | | **8** | Output | The frequency signal output (Square Wave) | | **14** | Vcc | Positive Power Supply (+3.3V or +5V) | --- ### 4. Technical Characteristics * **Frequency Stability:** Usually ranges from ±25ppm to ±100ppm, ensuring the clock signal does not drift significantly with temperature changes. * **Hermetic Sealing:** The "MHO" series is housed in a metal "can" that is resistance-welded to protect the quartz crystal from moisture and atmospheric contaminants. * **Applications:** * Legacy industrial controllers. * Network routers and switches. * Embedded systems requiring a robust through-hole clock source. * Test and measurement equipment. --- ### 5.
