The **MHO+32FAAD-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, often manufactured by companies like **MtronPTI**. This component belongs to the frequency control category and is used to provide a precise clock signal for electronic circuits. --- ### 1. General Specifications Based on the standard nomenclature for this series, here are the technical characteristics: | Parameter | Specification | |:---|:---| | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage ($V_{cc}$)** | +3.3V or +5.0V (Standard for MHO series) | | **Frequency Range** | Typically 1.0 MHz to 100.0 MHz (Specific to exact sub-model) | | **Operating Temperature** | Standard Industrial/Commercial ranges available | ### 2. Breakdown of the Part Number While internal manufacturer codes vary, the "MHO" series generally follows this structure: * **MHO:** Identifies the product series (Metal Half-size or Full-size Thru-hole Oscillator). * **3:** Usually indicates the Voltage (e.g., 3.3V). * **2:** Often refers to the Frequency Stability (e.g., ±50ppm or ±100ppm). * **FAAD:** These are internal suffixes for Symmetry, Operating Temperature range, and Output Load. * **-R:** Indicates **RoHS Compliance** (Lead-free). ### 3. Key Pinout Configuration For a standard 14-pin DIP package crystal oscillator, only four pins are typically functional: | Pin Number | Function | Description | |:---:|:---|:---| | **1** | NC or E/D | No Connection or Tri-state Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square wave) | | **14** | $V_{cc}$ | Power Supply Input | ### 4. Common Applications * **Microcontrollers:** Providing the external clock source for CPUs. * **Networking:** Synchronizing data transmission in Ethernet or Fiber switches. * **Industrial Control:** Timing for PLC (Programmable Logic Controllers). * **Legacy Systems:** Used in older hardware designs that require through-hole mounting rather than SMD (Surface Mount). ---
