Based on the part number **MHO+46FBD-R**, this component is a specialized **Crystal Oscillator** typically manufactured by **MtronPTI**. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. General Specifications The MHO series represents a line of high-reliability, metal-can (DIP) packaged crystal oscillators. | Parameter | Specification | | :--- | :--- | | **Part Type** | Crystal Clock Oscillator | | **Package Style** | 14-pin DIP (Standard metal can, 4-pins used) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage ($V_{DD}$)** | Usually 5.0V (Standard for MHO series) | | **Termination** | Through-hole | --- ## 2. Part Number Breakdown (MHO+46FBD-R) The nomenclature defines the specific environmental and electrical tolerances: * **MHO**: Series designation (14-pin DIP, 5.0V Oscillator). * **+**: RoHS Compliant (Lead-free). * **4**: Stability code. This typically signifies a frequency stability of **±50 ppm**. * **6**: Operating Temperature code. Usually represents **-40°C to +85°C** (Industrial Grade). * **F**: Symmetry/Duty Cycle. Typically indicates a **45/55%** duty cycle. * **BD**: Specific frequency or internal revision code (requires specific manufacturer datasheet for the exact MHz value, often 1.000 to 100.000 MHz). * **-R**: Packaging suffix (e.g., Tube or Tray). --- ## 3. Key Electronic Characteristics ### Power and Signal * **Current Consumption:** Typically ranges from 15mA to 60mA depending on the target frequency. * **Logic Levels:** * Logic High ($V_{OH}$): 90% of $V_{DD}$ minimum. * Logic Low ($V_{OL}$): 10% of $V_{DD}$ maximum. * **Rise/Fall Time:** Fast transition times (usually < 6ns) to support high-speed digital logic. ### Physical Design The metal package acts as a Faraday cage, providing excellent **EMI (Electromagnetic Interference) shielding**. This makes it ideal for sensitive communication equipment or industrial controllers where noise immunity is critical. --- ## 4. Pin Configuration (14-Pin DIP) While the package has 14 pin spots, only 4 pins are physically present or electrically active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-State | No connection or Output Enable/Disable | | **7** | GND | Case and Circuit Ground | | **8** | Output | The generated clock signal | | **14** | $V_{DD}$ | Positive Supply Voltage (+5.0V) | --- ## 5. Typical Applications * **Microprocessor Clocks:** Providing the heartbeat for CPUs and MCUs. * **Networking:** Timing for Ethernet and data transmission. * **Industrial Control:** Reliable timing in harsh temperature environments.
