The **MHO+52FCG-R** is a specific series of high-precision, high-stability **Crystal Oscillators** (specifically categorized under the MHO series by manufacturers like MtronPTI). These components are essential in providing a stable clock signal for digital circuits. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. Component Overview The "MHO" series typically refers to **Metal Hybrid Oscillators**. These are active components, meaning they require a power supply to generate a continuous square wave output at a predefined frequency. ### 2. Technical Specifications While specific data can vary slightly based on the full part number suffix, the standard parameters for this series are: | Parameter | Specification | | :--- | :--- | | **Package Type** | 14-pin DIP (Full Size) or 8-pin DIP (Half Size) Metal Can | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage (Vcc)** | Typically +5.0V DC (indicated by the '5' in the code) | | **Frequency Stability** | ±100ppm to ±25ppm (depending on grade) | | **Operating Temperature** | 0°C to +70°C (Standard) or -40°C to +85°C (Industrial) | | **RoHS Status** | Compliant (indicated by the 'R' suffix) | --- ### 3. Pin Configuration (Typical 14-pin DIP) For the standard metal package, the internal connections are usually as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / ED | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | Power Supply (+5V) | --- ### 4. Key Features * **Hermetic Seal:** The metal "can" package is vacuum-sealed or filled with nitrogen to protect the quartz crystal from humidity and oxidation, ensuring long-term frequency stability. * **Low Jitter:** Designed to provide a clean timing signal with minimal phase noise, which is critical for high-speed data communication. * **Built-in Load Capacitance:** Unlike passive crystals, this oscillator includes the necessary oscillation circuitry and load capacitors internally. ### 5. Common Applications * **Microprocessors:** Providing the master clock for CPU operations. * **Networking:** Timing for Ethernet controllers and routers. * **Embedded Systems:** Industrial controllers requiring 5V logic levels. * **Legacy Hardware:** Often used in older computer repairs or industrial equipment due to the through-hole (DIP) form factor. --- ### 6. Decoding the Part Number (General Logic) * **MHO:** Series Prefix (Metal Hybrid Oscillator). * **+:** Often indicates RoHS compliance or a specific revision. * **5:** Indicates 5.0 Volt operation. * **2:** Often refers to the frequency stability grade (e.g., +/- 50ppm). * **F:** Frequency control or specific temperature range indicator. * **CG:** Symmetry or Output Load characteristics. * **R:** RoHS Compliant.
