The **MHO+24TAAD-R** is a specific series of high-precision crystal oscillators manufactured by **MtronPTI**. These components are typically used as frequency references in telecommunications, aerospace, and industrial electronics. ### 1. Component Identification | Parameter | Detail | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Series** | MHO Series | | **Package Style** | 14-pin DIP (Dual In-line Package) | | **Technology** | HCMOS/TTL Compatible Output | --- ### 2. Technical Specifications The "MHO+24TAAD-R" part number follows a specific nomenclature. Below is the breakdown of its primary electronic characteristics: * **Frequency Range:** Typically available from 1.000 MHz up to 125.000 MHz (The specific frequency is usually marked on the top of the physical part). * **Operating Voltage:** Generally 5.0V or 3.3V (depending on the specific sub-suffix). * **Stability:** High-frequency stability often measured in ±25ppm to ±100ppm depending on temperature range. * **Output Drive:** Capable of driving HCMOS or TTL logic levels, making it versatile for digital circuit integration. * **RoHS Compliance:** The **"-R"** suffix indicates that the part is Lead-Free and RoHS compliant. --- ### 3. Pin Configuration (Typical 14-pin DIP) Though it resides in a 14-pin footprint, only 4 pins are usually active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-State | No connection or Output Enable/Disable | | **7** | GND | Case and Circuit Ground | | **8** | Output | The generated clock signal | | **14** | Vcc | Positive Power Supply (+5V or +3.3V) | --- ### 4. Application Areas These oscillators are designed for environments where reliability and low jitter are required: 1. **Networking:** Routers, switches, and fiber-optic communication. 2. **Microprocessors:** Providing the "heartbeat" or clock cycle for CPUs and MCUs. 3. **Industrial Controls:** Timing for PLCs and automated factory equipment. 4. **Legacy Systems:** Because of the 14-pin DIP package, they are often used in older hardware or robust industrial designs that favor through-hole components over SMD. --- ### 5. Part Number Breakdown (Pattern) * **MHO:** MtronPTI High-reliability Series. * **+:** Positive voltage characteristic or RoHS compliance indicator. * **24:** Refers to specific temperature range/stability (often -40°C to +85°C). * **T:** Usually indicates Tri-state functionality. * **AAD:** Internal code for specific custom output/symmetry. * **-R:** RoHS Compliant.
