The **MHO+22FAD-R** is a specific type of **Crystal Oscillator** (often categorized under Frequency Control products). It is a precision electronic component used to generate a stable clock signal for digital circuits. --- ### 1. Key Technical Specifications Below are the typical technical parameters associated with this specific part series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Full Size) / 4-pins used | | **Output Type** | HCMOS / TTL | | **Voltage Supply** | Typically 5.0V (Standard for MHO series) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±100 ppm (Standard for 'A' suffix) | --- ### 2. Part Number Breakdown While manufacturer coding can vary slightly (often produced by MtronPTI), the alphanumeric string generally breaks down as follows: * **MHO:** Identifies the series (Metal Thru-Hole Oscillator). * **+:** Often indicates RoHS compliance (Lead-free). * **2:** Represents the supply voltage (e.g., 2 = 5.0V). * **2:** Represents the temperature range and stability. * **FAD:** These characters usually denote the output symmetry (Duty Cycle) and specific frequency calibration. * **-R:** Indicates "RoHS Compliant." --- ### 3. Pin Configuration (14-Pin DIP Package) Even though the casing is the size of a 14-pin integrated circuit, only 4 pins are usually present: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square wave) | | **14** | Vcc | Positive Power Supply (+5V) | --- ### 4. Applications The MHO+22FAD-R is commonly found in legacy and industrial hardware where timing stability is critical: * **Microprocessor Clocks:** Providing the heartbeat for CPUs. * **Networking Equipment:** Synchronizing data transmission in switches or routers. * **Industrial Controllers:** Used in PLCs (Programmable Logic Controllers) where through-hole mounting is preferred for durability. * **Test & Measurement:** Oscilloscopes and signal generators. ### 5. Circuit Integration Example To use this part, you generally place a 0.01µF to 0.1µF bypass capacitor between Vcc and GND to filter noise. ```c // Concept: Standard Oscillator Connection [Vcc (+5V)] ----+---- [Pin 14] | [0.1uF Cap] | [GND] ----------+---- [Pin 7] [Pin 8] ------------> [Clock Input of MCU/IC] ```
