The **MHO+65TAAD-R** is a high-performance **Crystal Oscillator** (specifically a Clock Oscillator) manufactured by MtronPTI. It is designed for high-frequency stability and reliability in telecommunications and data processing applications. --- ### 1. Key Technical Specifications Below are the primary electronic characteristics for the MHO+ series: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | Typically 1.000 MHz to 125.000 MHz | | **Supply Voltage (Vcc)** | +5.0 VDC (±10%) | | **Package Type** | 14-pin DIP (DIL) - Full size metal can | | **Output Type** | CMOS / TTL Compatible | | **Frequency Stability** | ±100 ppm (Standard), options for ±25/50 ppm | | **Operating Temperature** | 0°C to +70°C (Standard) | | **Duty Cycle** | 40/60% to 45/55% | --- ### 2. Component Breakdown The part number follows a specific nomenclature used by MtronPTI: * **MHO+**: The series identifier. "MHO" stands for Mtron High-reliability Oscillator, and the "+" indicates it is the lead-free/RoHS compliant version. * **6**: Indicates the Supply Voltage (typically 5.0V for this series). * **5**: Represents the Frequency Stability (5 usually denotes ±100ppm). * **T**: Denotes the Output Load/Symmetry (typically 40/60% or 45/55% symmetry). * **AA**: Temperature Range (Standard commercial 0°C to +70°C). * **D**: Pin 1 functionality (e.g., Tri-state enable/disable). * **-R**: RoHS Compliant. --- ### 3. Pin Configuration (14-pin DIP) Though the package is a 14-pin size, it typically only uses four active electrical connections: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | E/D or NC | Enable/Disable (Tri-state) or No Connect | | **Pin 7** | GND | Case and Circuit Ground | | **Pin 8** | Output | The generated clock signal (Square Wave) | | **Pin 14** | Vcc | +5.0V Supply Voltage | --- ### 4. Application Use Cases * **Network Equipment:** Used in routers and switches for timing synchronization. * **Industrial Control:** Providing stable clock pulses for microprocessors and FPGAs. * **Legacy Hardware:** Because it uses the 14-pin DIP "Full Size" metal can, it is often found in older industrial computers or high-reliability legacy systems.
