The **MHO+48TAAD-R** is a specific part number for a **Crystal Oscillator**, typically manufactured by companies like MtronPTI. These components are essential in electronic circuits for providing a stable clock signal. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | A complete oscillator circuit including the crystal and electronics. | | **Package Style** | 14-pin DIP (Full Size) | A metal "can" package with 4 active pins (DIP-14 footprint). | | **Output Type** | CMOS / TTL | Provides a square wave signal compatible with standard logic circuits. | | **Operating Voltage** | 5.0V DC | Requires a stable 5V power supply to operate. | | **Stability** | ±100 ppm (Typical) | Frequency stability over the operating temperature range. | | **Frequency Range** | 1.0 MHz to 100 MHz+ | The specific frequency depends on the exact sub-variant ordered. | --- ### 2. Pin Configuration (DIP-14 Layout) Although it has the physical size of a 14-pin DIP integrated circuit, only 4 pins are usually present or functional: 1. **Pin 1 (NC or E/D):** No Connection or Tri-state Enable/Disable control. 2. **Pin 7 (GND):** Connected to the system ground and the metal case for shielding. 3. **Pin 8 (Output):** The generated clock signal (Square Wave). 4. **Pin 14 (Vcc):** +5V Power Supply input. --- ### 3. Electronic Functionality The MHO+48TAAD-R performs the following roles in a circuit: * **Frequency Generation:** It uses a quartz crystal wafer that vibrates at a precise frequency when electricity is applied (Piezoelectric effect). * **Clock Sourcing:** It acts as the "heartbeat" for microprocessors, digital signal processors (DSPs), and communication interfaces. * **Waveform Shaping:** Internal circuitry converts the crystal's analog resonance into a clean digital square wave (CMOS/TTL compatible). --- ### 4. Application Areas * **Legacy Computing:** Replacement parts for older industrial motherboards or embedded systems. * **Test Equipment:** Providing reference frequencies for oscilloscopes or signal generators. * **Communications:** Timing for networking hardware requiring 5V logic. ---
