The **MHO+68TBD-R** is a specific part number typically associated with **crystal oscillators**, specifically those manufactured by **MtronPTI**. This series is known for its high-reliability performance in industrial and communication applications. --- ### 1. Key Technical Specifications Based on the standard nomenclature for the MHO series, here are the primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Output Type** | TTL / HCMOS Compatible | | **Supply Voltage** | 5.0V (Standard for + series) | | **Package Style** | 14-pin DIP (Full size) or 8-pin DIP (Half size) | | **Mounting Type** | Through-Hole | | **Frequency Range** | Typically 1.0 MHz to 100.0 MHz (Depends on specific value) | --- ### 2. Detailed Part Number Breakdown The alphanumeric code provides specific details about the component's tolerances and features: * **MHO**: Represents the Series (Metal Hermetic Oscillator). * **+**: Indicates a 5.0 Volt supply voltage. * **6**: Refers to the Frequency Stability (Commonly ±25ppm or ±50ppm depending on the specific datasheet revision). * **8**: Refers to the Operating Temperature Range (Often -40°C to +85°C for Industrial grade). * **T**: Indicates "Tri-state" functionality (allows the output to be disabled/disconnected). * **BD**: Specific internal factory codes or sub-specifications for symmetry and rise/fall times. * **-R**: RoHS Compliant (Lead-free). --- ### 3. Functional Pinout (Standard 14-Pin DIP) While the physical housing has 14 pins, usually only 4 are electrically active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-state | Enable/Disable control | | **7** | GND | Case and Circuit Ground | | **8** | Output | The generated clock signal | | **14** | +Vcc | Positive Power Supply (5V) | --- ### 4. Typical Applications These oscillators are designed for environments where stability and durability are required: 1. **Telecommunications**: Timing for networking switches and routers. 2. **Industrial Controllers**: Clocking for PLCs and embedded systems. 3. **Legacy Computing**: Replacement parts for older motherboards or timing circuits requiring 5V logic.
