Based on your query, the **MHO+32FDG-R** refers to a specific series of **Active Crystal Oscillators** (frequently associated with brands like *Mercury Electronic*). These components are critical for providing a stable clock signal in digital circuits. --- ## 1. Component Overview The MHO series generally consists of HCMOS/TTL compatible crystal oscillators housed in a standard 14-pin DIP (Dual In-line Package) metal enclosure, though only 4 pins are active. ### Technical Specifications | Parameter | Typical Value / Description | | :--- | :--- | | **Package Type** | DIP-14 (Full size) | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | Usually 3.3V or 5.0V (Model dependent) | | **Frequency Stability** | ±25ppm to ±100ppm | | **Operating Temperature** | -10°C to +70°C (Standard) | | **Features** | Hermetically sealed metal case for EMI shielding | --- ## 2. Pin Configuration Even though the package has the physical footprint of a 14-pin IC, only four pins are used to functionalize the oscillator: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Ground connection | | **8** | Output | The generated clock frequency signal | | **14** | Vcc | Power supply input | --- ## 3. Key Electronic Characteristics * **Frequency Generation:** Unlike a passive crystal (which requires external capacitors and an inverter), this is an **Active Oscillator**. It contains the quartz crystal and the oscillation circuitry inside one package. * **Load Capacitance:** Typically optimized for a 15pF to 50pF load. * **Rise/Fall Time:** Designed for high-speed digital switching, usually in the range of 5ns to 10ns. * **EMI Shielding:** The metal "can" is grounded through pin 7, which significantly reduces electromagnetic interference (EMI) compared to ceramic resonators. --- ## 4. Common Applications * **Microprocessors:** Providing the base heartbeat for CPUs. * **Industrial Controllers:** Timing for PLCs and embedded systems. * **Networking:** Synchronizing data transmission in Ethernet or Serial interfaces. * **Legacy Hardware:** Often found in older computing equipment due to the robust DIP-14 form factor. ---
