The **MHO+45FAAG-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, specifically in a Full-Size (14-pin DIP) metal package. These components are used to generate a precise clock frequency for digital circuits. --- ### 1. Technical Specifications Below are the typical characteristics of the MHO+ series oscillators (manufactured by companies like MtronPTI): | Parameter | Typical Value / Description | | :--- | :--- | | **Frequency** | Determined by the specific marking (often in MHz) | | **Package Type** | 14-Pin DIP (Full Size) Metal Can | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage ($V_{cc}$)** | Usually +5.0V DC | | **Stability** | Generally ±50ppm or ±100ppm | | **Operating Temp** | 0°C to +70°C (Standard Commercial) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature generally follows this logic: * **MHO:** Series identifier (High-speed CMOS/TTL Oscillator). * **+:** Often indicates a specific lead-free or enhanced version. * **45:** This usually refers to the stability and duty cycle (e.g., 45/55% duty cycle). * **F:** Frequency stability code (often ±100ppm). * **AA:** Operating temperature range (usually 0 to 70°C). * **G-R:** "G" may refer to the pin configuration (Grounded case), and **"-R"** signifies **RoHS Compliance**. --- ### 3. Pin Configuration (14-Pin DIP Package) Even though the package has 14 pins physically, only 4 are usually electrically active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-State | No connection or Output Enable/Disable | | **7** | GND | Ground / Case Ground | | **8** | Output | The generated clock signal (Square wave) | | **14** | $V_{cc}$ | Power Supply (+5V) | --- ### 4. Common Applications * **Microprocessors:** Providing the base heartbeat for CPUs. * **Embedded Systems:** Timing for microcontrollers and FPGAs. * **Legacy Hardware:** Industrial motherboards and communication equipment. * **Data Processing:** Synchronization for serial and parallel data buses.
