The **MHO+15FAD-R** is a specific series of **Crystal Clock Oscillators** typically manufactured by companies like MtronPTI. These components are essential in digital electronics for providing a precise and stable timing signal (clock pulse). Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. Key Technical Specifications | Parameter | Specification Detail | | :--- | :--- | | **Component Type** | Crystal Clock Oscillator (XO) | | **Package Style** | 14-pin DIP (Dual In-line Package) - often "Half Size" or "Full Size" | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | Typically 5.0V DC (Standard for the MHO series) | | **Frequency Range** | Usually ranges from 1.000 MHz to 100.000 MHz | | **Stability** | ±100ppm (standard), with options for ±50ppm or ±25ppm | | **Operating Temperature** | 0°C to +70°C (Commercial Grade) | --- ### 2. Functional Breakdown #### **The "MHO" Series Meaning** The "MHO" prefix identifies the physical package and the logic family. It indicates a metal-can package designed for through-hole mounting on a PCB. These are known for their durability and EMI (Electromagnetic Interference) shielding properties. #### **Pin Configuration** Though it looks like a 14-pin integrated circuit, it usually only utilizes 4 functional pins: * **Pin 1:** NC (No Connection) or Tri-state Enable/Disable. * **Pin 7:** Ground (Case). * **Pin 8:** Output (The actual clock signal). * **Pin 14:** Vcc (+5V Power Supply). #### **The "R" Suffix** In electronic component nomenclature, the **-R** usually signifies **RoHS Compliance**. This means the part is manufactured without hazardous substances like lead, making it suitable for modern environmental standards. --- ### 3. Common Applications Because of its high stability and 5V operation, this part is frequently found in: 1. **Legacy Computing:** Providing the master clock for microprocessors and microcontrollers. 2. **Industrial Controllers:** Timing for PLCs and automated machinery. 3. **Networking Equipment:** Synchronizing data transmission in older hubs and switches. 4. **Test Equipment:** Oscilloscopes and signal generators. --- ### 4.
