The **MHO+65FGD-R** is a high-performance, programmable crystal oscillator (SPXO) manufactured by **MtronPTI**. It belongs to the MHO series, which is widely used in applications requiring high stability and precision timing. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Output Type** | CMOS / TTL Compatible | | **Frequency Range** | Typically 1.000 MHz to 125.000 MHz | | **Supply Voltage (Vcc)** | +5.0 VDC (Standard) | | **Frequency Stability** | ±50 ppm (standard for "G" grade) | | **Operating Temp Range** | 0°C to +70°C (Standard) | | **Package Type** | 14-pin DIP (Full Size) | | **Load Capacitance** | 15 pF to 50 pF | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the specific features of this component: * **MHO**: Series designation (Metal, High-reliability, 14-pin DIP package). * **+**: Lead-free / RoHS compliant indicator. * **6**: Voltage indicator (6 usually denotes 5.0V operation). * **5**: Stability code (5 usually represents ±50ppm). * **F**: Symmetry/Duty Cycle (typically 40/60% or 45/55%). * **GD**: Custom frequency or specific internal wiring code. * **-R**: RoHS Compliant. --- ### 3. Pin Configuration (14-Pin DIP) Even though it is a 14-pin package, only 4 pins are usually active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or E/D | No connection or Tri-state Enable/Disable | | **7** | GND | Case Ground | | **8** | Output | Clock Signal Output | | **14** | Vcc | +5.0V Power Supply | --- ### 4. Application Areas Because of its robust metal casing and through-hole design, the MHO+65FGD-R is commonly found in: * **Legacy Computing:** Motherboards and industrial controllers requiring 5V logic. * **Networking:** Synchronous Ethernet and data processing units. * **Test Equipment:** Oscilloscopes and signal generators. * **Industrial Automation:** PLCs and timing circuits in harsh environments. --- ### 5. Key Advantages * **Noise Immunity:** The metal "can" package acts as a Faraday cage, reducing EMI (Electromagnetic Interference). * **Durability:** Through-hole mounting provides superior mechanical strength compared to SMD (Surface Mount Devices). * **Consistency:** MtronPTI oscillators are known for low jitter and long-term aging stability.
