The **MHO+13FAAG-R** is a specific series of **Quartz Crystal Oscillators** manufactured by MtronPTI. These components are used to provide a precise clock signal for digital circuits. --- ## 1. Technical Specifications Below are the primary electrical and physical characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Full Size) - Through Hole | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | Typically 5.0V (Standard for MHO series) | | **Frequency Range** | 1.000 MHz to 150.000 MHz (Specific to exact sub-model) | | **Operating Temperature** | Commercial or Industrial grades available | | **RoHS Status** | Compliant (Indicated by the '-R' suffix) | --- ## 2. Part Number Breakdown Understanding the nomenclature helps identify the exact features of the component: * **MHO**: The series prefix designating a 5.0V Full-Size (14-pin DIP) HCMOS/TTL oscillator. * **+**: Often indicates a lead-free/RoHS compliant process. * **13**: Represents the **Frequency Stability**. In the MtronPTI system, "1" usually denotes $\pm 100$ ppm, and "3" denotes the temperature range (0°C to +70°C). * **F**: Denotes the **Duty Cycle** (typically 40/60% or 45/55%). * **AA**: Internal codes for specific frequency output or package height. * **G**: Denotes the **Tri-state/Enable-Disable** function (Pin 1 is used to enable/disable the output). * **-R**: Explicitly confirms **RoHS Compliance**. --- ## 3. Key Electronic Functions ### A. Clock Generation The device combines a quartz crystal blank with an oscillation circuit and an output buffer. When power is applied, it vibrates at a fixed frequency to provide a "heartbeat" for microprocessors or FPGAs. ### B. Tri-State Function (Pin 1) The "G" designation means this part supports an enable/disable function: * **High (or Floating):** The oscillator outputs the clock signal on Pin 8. * **Low:** The output goes into a high-impedance state, reducing power consumption and allowing other devices to use the line. ### C. Mechanical Layout (14-Pin DIP) While it is called a 14-pin DIP, most oscillators only have 4 functional pins: 1. **Pin 1:** Enable/Disable (Tri-state) 2. **Pin 7:** Ground (Case Ground) 3. **Pin 8:** Output Signal 4. **Pin 14:** $V_{cc}$ (+5.0V) --- ## 4. Common Applications * **Legacy Computing:** Motherboards and peripheral cards requiring 5V logic. * **Industrial Control:** Timing for PLCs and embedded controllers. * **Networking:** Synchronizing data transmission in older telecommunications equipment. * **Test Equipment:** Providing a stable reference frequency for signal generators.
