The **MHO+68TAAD-R** is a specific part number typically associated with **MHO+ series crystal oscillators** manufactured by **MtronPTI**. These components are essential in electronics for generating a precise, stable clock signal for timing applications. --- ### 1. Key Technical Specifications Based on the standard nomenclature for the MtronPTI MHO+ series, here is a breakdown of the typical specifications: | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Half Size | | **Frequency Range** | Typically 1.0 MHz to 100 MHz (Specific to customer order) | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | Usually 5.0V or 3.3V | | **Stability** | Generally ±50ppm or ±100ppm | | **RoHS Status** | Compliant (Indicated by the "R" suffix) | --- ### 2. Part Number Breakdown While manufacturer codes can vary slightly, here is the common logic for this series: * **MHO+**: The series identifier for MtronPTI Half-Size High-Frequency Oscillators. * **68**: Often refers to the stability and duty cycle (e.g., ±50ppm, 40/60% duty cycle). * **T**: Usually indicates the operating temperature range (Industrial: -40°C to +85°C). * **AA**: Internal codes for specific frequency/output configurations. * **D**: Often indicates the Pin 1 "Tri-state" (Enable/Disable) function. * **-R**: Indicates **RoHS Compliant** (Lead-free). --- ### 3. Applications and Usage This part is commonly used in legacy and industrial hardware where high reliability and through-hole mounting are required: 1. **Industrial Controls:** Providing stable clocking for microprocessors in harsh environments. 2. **Telecommunications:** Timing for data transmission hardware. 3. **Embedded Systems:** Used in motherboards or interface cards that still utilize DIP sockets or through-hole PCB assembly. ### 4. Typical Connection Diagram If you are looking to integrate this part, the standard 4-pin (half-size DIP) layout is as follows: ```text Pin 1: Tri-state (Enable/Disable) or No Connect Pin 7: Ground (Case) Pin 8: Output (Clock Signal) Pin 14: Vcc (+ Power Supply) ``` ---
