The **MHO+17FBG-R** refers to a high-precision, industrial-grade crystal oscillator, typically part of the **MHO Series** (often associated with manufacturers like Mercury Electronic or similar timing component specialists). These components are critical in electronics for providing a stable clock signal to microprocessors and communication buses. --- ### 1. Technical Specifications Below is a breakdown of the typical electronic characteristics for this specific part series: | Parameter | Specification (Typical) | Notes | | :--- | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | Active timing device | | **Package Type** | 14-Pin DIP (Full Size) | Metal can package for EMI shielding | | **Output Type** | HCMOS / TTL | Compatible with most digital logic | | **Supply Voltage** | 5.0V (Standard) | Common in legacy and industrial systems | | **Frequency Stability** | ±25ppm to ±100ppm | Dependent on the specific suffix | | **Operating Temp** | -10°C to +70°C | Standard commercial/industrial range | --- ### 2. Key Features and Construction The MHO+17FBG-R is designed for durability and signal integrity. Its construction includes several internal parts: * **Quartz Crystal Plate:** The core resonating element that determines the frequency. * **Oscillator IC:** An internal integrated circuit that provides the necessary gain and feedback to maintain oscillation. * **Bypass Capacitor:** Often integrated inside the metal can to filter power supply noise. * **Metal Housing:** The "can" acts as a Faraday cage, protecting the internal signal from Electromagnetic Interference (EMI) and reducing emissions. --- ### 3. Pin Configuration (14-Pin DIP Style) Even though the package has the footprint of a 14-pin IC, only four pins are typically active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / ED | No connection or Enable/Disable (Tristate) | | **7** | GND | Circuit ground / Case ground | | **8** | Output | The generated clock signal (Square wave) | | **14** | Vcc | +5.0V Power Supply | --- ### 4. Part Number Decoding The suffix **-R** usually denotes **RoHS Compliance**, meaning the part is manufactured without hazardous substances like lead. ### 5. Application Areas * **Legacy Computing:** Motherboards and peripheral controllers. * **Industrial Automation:** PLCs and timing modules. * **Networking:** Routers and switches requiring stable clocking for data packets. * **Embedded Systems:** Providing the heartbeat for 8-bit or 16-bit microcontrollers.
