The **MHO+64FFD-R** is a high-precision, high-frequency crystal oscillator (OCXO/TCXO family) typically used in telecommunications and data networking. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. General Specifications The part number follows a specific nomenclature used by manufacturers (often MtronPTI). | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator | | **Frequency Range** | Typically 1.000 MHz to 100.000 MHz (Varies by sub-model) | | **Package Style** | 14-pin DIP (Full size) or Half-size metal can | | **Output Type** | CMOS / TTL Compatible | | **Operating Voltage** | Usually +5.0V or +3.3V DC | ### 2. Part Number Breakdown (MHO+64FFD-R) The alphanumeric string defines the physical and electrical tolerance of the component: * **MHO**: Series designation (High-reliability series). * **+**: Lead-free / RoHS compliant indicator. * **64**: Stability/Temperature code (indicates frequency stability over a specific temperature range). * **F**: Symmetry / Duty Cycle (e.g., 40/60% or 45/55%). * **F**: Pinout configuration. * **D**: Operating Temperature range (Commonly -40°C to +85°C for industrial use). * **-R**: RoHS Compliant. ### 3. Key Technical Characteristics #### Electrical Performance * **Frequency Stability**: Typically ±20ppm to ±100ppm depending on the specific "64" classification. * **Rise/Fall Time**: Fast transitions (usually < 5ns) to ensure timing accuracy in high-speed digital circuits. * **Supply Current**: Low power consumption, typically drawing between 15mA and 45mA depending on the output frequency. #### Mechanical & Environmental * **Hermetic Sealing**: The metal casing is resistance-welded to prevent moisture ingress, ensuring long-term frequency aging stability. * **Shock/Vibration Resistance**: Designed to withstand MIL-STD-202 specifications, making it suitable for industrial machinery. ### 4. Common Applications Due to its stability and metal-can shielding (which reduces Electromagnetic Interference - EMI), this part is found in: 1. **Network Switches/Routers**: Providing the master clock for data packets. 2. **Industrial Controllers**: Timing for PLCs and automation hardware. 3. **Test Equipment**: Reference signals for oscilloscopes and signal generators. ---
