The **MHO+75FAAD-R** is a specific part number for a high-performance **Crystal Oscillator** manufactured by **MtronPTI**. It is primarily used to provide a stable clock signal for digital circuits. --- ### 1. Key Technical Specifications Below are the primary electrical and physical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Output Frequency** | Fixed (Determined by specific suffix, often 1.0 MHz to 150 MHz range) | | **Frequency Stability** | ±50 ppm (standard for this series) | | **Supply Voltage (Vcc)** | +5.0 VDC | | **Output Type** | HCMOS / TTL Compatible | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Package Style** | 14-pin DIP (Half-Size) Metal Can | | **RoHS Status** | Compliant (-R suffix) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the exact features of the device: * **MHO+**: Represents the product series (5.0V, Half-Size DIP, HCMOS/TTL). * **7**: Indicates the Frequency Stability (±50 ppm). * **5**: Indicates the Operating Temperature Range (-40°C to +85°C). * **F**: Refers to the Symmetry/Duty Cycle (typically 40/60% or 45/55%). * **AA**: Internal codes for specific output configurations or packaging. * **D**: Tri-state enable/disable function (allows the output to be turned off). * **-R**: RoHS Compliant (Lead-free). --- ### 3. Pin Configuration Since this is a "Half-Size" DIP package, it usually utilizes four pins: 1. **Pin 1 (NC/Enable):** Tri-state Control. High or Open = Output Active; Low = High Impedance. 2. **Pin 7 (GND):** Ground connection. 3. **Pin 8 (Output):** The clock signal output. 4. **Pin 14 (Vcc):** +5.0V Power Supply. --- ### 4. Typical Applications Due to its rugged metal casing and industrial temperature rating, it is commonly found in: * **Industrial Automation:** PLCs and controller timing. * **Telecommunications:** Base stations and networking hardware. * **Embedded Systems:** Providing master clocks for microcontrollers and FPGAs. * **Legacy Systems:** Maintenance and repair of older 5V logic boards.
