Based on the part number **MHO+37FDD-R**, this component is a specific type of **high-frequency crystal oscillator**. These are critical components used for timing and frequency control in electronic circuits. Below is a detailed breakdown of its specifications and functions. --- ### 1. Component Identification The "MHO" series is typically manufactured by **MtronPTI**. This specific part is a high-reliability, fixed-frequency oscillator often used in industrial or communication environments. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full size | | **Output Type** | CMOS / TTL Compatible | | **RoHS Status** | The "-R" suffix indicates **RoHS Compliant** (Lead-free) | --- ### 2. Technical Specifications While the specific frequency is determined by the numeric code (if provided in a longer string), the MHO+37 series generally adheres to the following electrical parameters: * **Supply Voltage (Vcc):** Typically **+5.0V DC** (indicated by the "3" or "5" coding in various manufacturer schemes, but MHO+37 is standard 5V). * **Stability:** Usually ±25ppm to ±100ppm depending on the specific grade. * **Operating Temperature:** Generally -40°C to +85°C (Industrial Grade). * **Enable/Disable Function:** The "FDD" designation often refers to the Pin 1 configuration, usually meaning the output is "Always On" or has a specific "Tri-state" (High Impedance) functionality. --- ### 3. Pin Configuration (14-Pin DIP) Even though it is a 14-pin package, most of the pins are removed or not connected. Only 4 pins are active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or E/D | No Connection or Output Enable/Disable | | **7** | GND | Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | Power Supply (+5V) | --- ### 4. Applications This part is commonly found in older or "long-lifecycle" electronic systems because of its through-hole (DIP) mounting style. 1. **Microprocessor Clocks:** Providing the heartbeat for CPUs and MCUs. 2. **Network Hardware:** Used in switches and routers for data synchronization. 3. **Test & Measurement:** Oscilloscopes and signal generators. 4. **Legacy Industrial Control:** Reliable timing for PLC (Programmable Logic Controller) boards. --- ### 5.
