## MHO+53TAD-R: Technical Overview The **MHO+53TAD-R** is a specific model of a **Crystal Oscillator**, typically manufactured by companies like **MtronPTI**. This component is used to generate a precise clock signal for digital circuits. ### 1. Part Number Breakdown While naming conventions can vary slightly by manufacturer, the code generally follows this logic: | Segment | Meaning | Specification | | :--- | :--- | :--- | | **MHO** | Series Type | Metal Hybrid Oscillator (usually 14-pin or 8-pin DIP) | | **+** | RoHS Compliance | Lead-free / RoHS compliant | | **5** | Operating Voltage | 5.0 Volts DC | | **3** | Stability/Temp | Typically denotes ±50ppm or ±100ppm stability | | **T** | Output Type | TTL / CMOS Compatible | | **A** | Symmetry/Duty Cycle | 40/60% or 45/55% Duty Cycle | | **D** | Tri-state Function | Includes Pin 1 Enable/Disable function | | **R** | Frequency | Specific frequency code (needs full datasheet for Hz value) | --- ### 2. Key Technical Specifications The MHO series is known for its "Full Size" or "Half Size" metal can package, which provides excellent EMI shielding. * **Package Style:** 14-pin DIP (Dual In-line Package) - often only 4 pins are physically present. * **Supply Voltage ($V_{cc}$):** 5.0V ± 10%. * **Frequency Range:** Usually available from 1.0 MHz to 150.0 MHz. * **Operating Temperature:** Typically 0°C to +70°C (Commercial) or -40°C to +85°C (Industrial). * **Output Load:** 15pF to 50pF (CMOS). --- ### 3. Pin Configuration (Typical 14-pin DIP) Though it has the footprint of a 14-pin IC, most oscillators only use four corners: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Tri-State (E/D) | Logic High or Open: Output active; Logic Low: High Impedance | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | $V_{cc}$ | +5.0V Power Supply | --- ### 4. Applications The MHO+ series is commonly used in legacy and industrial hardware where stable timing is required: * **Microprocessor Clocks:** Providing the heartbeat for CPUs. * **Networking Gear:** Switches and routers requiring synchronized data transmission. * **Embedded Systems:** Industrial controllers and automation logic.
