The **MHO+74FFG-R** is a specific series of high-frequency crystal oscillators manufactured by **MtronPTI**. These components are critical in telecommunications and data processing for providing stable clock signals. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The MHO+ series typically follows the industry-standard 14-pin DIP (Dual In-line Package) footprint, though it often only utilizes 4 pins. | Feature | Specification | | :--- | :--- | | **Package Type** | 14-pin DIP (Compatible) / Metal Can | | **Frequency Range** | Typically 1.0 MHz to 150.0 MHz | | **Output Type** | HCMOS / TTL | | **Operating Voltage** | 5.0V (Standard for the MHO series) | | **RoHS Compliant** | Yes (Indicated by the **-R** suffix) | --- ### 2. Part Number Breakdown To understand the specific electronic capabilities, we can decode the nomenclature: * **MHO**: Represents the product series (Metal Hollow Oscillator / HCMOS-TTL). * **+**: Usually denotes a specific revision or lead-free process improvement. * **7**: Refers to the Operating Temperature range (typically 0°C to +70°C). * **4**: Refers to the Frequency Stability (e.g., ±50 ppm or ±100 ppm depending on the datasheet revision). * **FFG**: Internal codes for specific output symmetry and pull-range requirements. * **-R**: Strictly indicates **RoHS Compliance** (Lead-free). --- ### 3. Pin Configuration The physical layout follows the standard "full-size" oscillator pinout: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Case Ground / Negative Power Supply | | **8** | Output | The generated clock signal (Square wave) | | **14** | Vcc | +5.0V DC Positive Power Supply | --- ### 4. Key Electronic Features * **High Drive Capability:** Designed to drive multiple CMOS or TTL loads without significant signal degradation. * **Hermetically Sealed:** The metal "can" package protects the internal quartz crystal from atmospheric moisture and EMI (Electromagnetic Interference). * **Low Jitter:** Optimized for high-speed data applications where timing precision is vital to prevent bit errors. --- ### 5. Common Applications Due to its robust metal package and 5V operation, it is commonly found in: 1. **Legacy Computing:** Motherboards or industrial PC-104 boards. 2. **Networking:** Routers and switches requiring a master clock. 3. **Industrial Control:** Timing for PLCs and automation hardware.
