The **MHO+16TAAD-R** is a specific part number typically associated with **Active Crystal Oscillators**, often manufactured by companies like MtronPTI or similar precision frequency control component suppliers. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. General Specifications The MHO series generally refers to high-reliability, metal-can (DIP) packaged clock oscillators. | Feature | Description | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Full size) or 8-pin DIP (Half size) - Typically 4 pins used | | **Output Type** | CMOS / TTL Compatible | | **Mounting Type** | Through-Hole | | **Enclosure** | Hermetically sealed metal case for EMI shielding | --- ### 2. Part Number Breakdown (Typical) While internal manufacturer codes vary, here is the standard logic for this series: * **MHO:** Series designation (High-speed CMOS/TTL). * **+:** Usually denotes RoHS compliance (Lead-free). * **16:** Frequency indicator (Likely **16.000 MHz**). * **T:** Temperature Stability / Range (Standard is often 0°C to +70°C or -40°C to +85°C). * **AA:** Output Load/Duty Cycle configuration (e.g., 50/50% duty cycle). * **D:** Tri-state Enable/Disable function (Pin 1 can be used to float the output). * **R:** Packaging suffix (e.g., Tube or specific Revision). --- ### 3. Key Electrical Characteristics These parts are designed to provide a stable clock signal for microprocessors, FPGAs, and digital communication circuits. #### **A. Power Requirements** * **Operating Voltage ($V_{DD}$):** Typically 3.3V or 5.0V DC. * **Current Consumption:** Low power, usually between 10mA and 45mA depending on the frequency and load. #### **B. Signal Integrity** * **Frequency Stability:** Usually ranges from $\pm 25$ ppm to $\pm 100$ ppm. * **Rise/Fall Time:** Fast transitions (typically $< 10ns$) to ensure clean digital clock edges. * **Load Capacitance:** Optimized for a 15pF to 50pF load. #### **C. Pin Configuration (4-Pin standard)** | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable (Tri-state) or No Connect | | **7** | GND | Ground / Case Ground | | **8** | Output | The generated clock signal (Square wave) | | **14** | $V_{DD}$ | Positive Power Supply | --- ### 4. Application Use Cases * **Digital Systems:** Providing the heartbeat for CPUs and MCUs. * **Networking:** Synchronizing data transmission in Ethernet or Serial interfaces. * **Industrial:** Used in environments where metal shielding (EMI protection) is required due to high noise. ---
