The **MHO+31FAAD-R** is a specific part number typically associated with a **Crystal Oscillator** or **Clock Oscillator**. These components are essential in electronic circuits for providing a precise timing signal (heartbeat) to microprocessors, FPGAs, and other digital systems. Below is a detailed breakdown of the technical specifications and characteristics of this component. --- ### 1. General Specifications Based on standard industry naming conventions for the MHO series (often manufactured by companies like MtronPTI or similar frequency control specialists), here are the typical technical parameters: | Feature | Description | | :--- | :--- | | **Component Type** | Crystal Clock Oscillator (XO) | | **Package Style** | 14-pin DIP (Dual In-line Package) - often 4 pins connected | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage ($V_{cc}$)** | Typically 5.0V (Standard for the MHO series) | | **Stability** | Usually $\pm$100ppm or $\pm$50ppm (depending on the full suffix) | | **Frequency Range** | Fixed frequency (The specific frequency is usually printed on the housing) | --- ### 2. Pin Configuration For a standard 14-pin DIP style oscillator like the MHO+ series, only four pins are functional. The internal layout usually follows this industry standard: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | NC or Tri-state | No Connection or Output Enable/Disable | | **Pin 7** | GND | Ground / Negative Supply | | **Pin 8** | Output | The generated clock signal (Square wave) | | **Pin 14** | $V_{cc}$ | Positive Power Supply (+5V) | --- ### 3. Key Characteristics * **A-Series Design:** The "A" in the part number often denotes specific temperature ranges or stability grades. Standard "A" parts usually operate from **0°C to +70°C**. * **Through-Hole Mounting:** The DIP package is designed for through-hole PCB mounting or insertion into IC sockets, making it popular for industrial equipment and legacy hardware. * **Reliability:** These oscillators are "Fixed Frequency," meaning they are factory-tuned and do not require external capacitors (load caps) to function, unlike a raw 2-pin crystal. --- ### 4. Typical Applications The MHO+31FAAD-R is commonly found in: 1. **Industrial Controllers:** Providing stable timing for PLCs. 2. **Legacy Computing:** Serving as the master clock for older CPU architectures. 3. **Networking Hardware:** Synchronizing data transmission in switches or routers. 4. **Test Equipment:** Used in signal generators or frequency counters. ---
