The **MHO+46TAD-R** is a specific series classification for a **Crystal Oscillator**, typically manufactured by companies like MtronPTI. These components are used to provide a precise clock signal for digital circuits. --- ### 1. Component Overview The MHO series generally refers to **TCXO (Temperature Compensated Crystal Oscillators)** or high-stability clock oscillators housed in a metal DIP (Dual In-line Package). | Feature | Specification (Typical) | | :--- | :--- | | **Package Type** | 14-pin DIP (Metal Can) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage** | Usually 5.0V or 3.3V | | **Stability** | High precision over temperature ranges | | **Mounting** | Through-hole | --- ### 2. Breakdown of the Part Number While specific manufacturer datasheets vary slightly, the alphanumeric code usually breaks down as follows: * **MHO:** Series identifier (Metal Hollow/High-reliability Oscillator). * **+:** Often indicates RoHS compliance (lead-free). * **4:** Typically represents the supply voltage (e.g., 4 = 5.0V). * **6:** Often represents the temperature stability/range code. * **TAD:** Technical parameters related to duty cycle and output load. * **R:** Packaging suffix (e.g., Tape & Reel or specific Revision). --- ### 3. Pin Configuration (Internal Layout) Most MHO 14-pin DIP oscillators only utilize 4 physical pins located at the corners of the 14-pin footprint: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground / Case Ground | | **8** | Output | The generated frequency (Square Wave) | | **14** | Vcc | Positive Power Supply | --- ### 4. Typical Applications These oscillators are used in environments where frequency stability is critical: * **Telecommunications:** Base stations and networking hardware. * **Test Equipment:** Oscilloscopes and frequency counters. * **Industrial Control:** Synchronizing complex logic in PLCs. * **Legacy Computing:** Timing for older microprocessor architectures. --- ### 5. Implementation Example To use this part in a circuit, you would connect it as follows: ```c // Schematic Logic [Vcc 5V] ----> Pin 14 [GND] ----> Pin 7 [Pin 8] ----> Digital Clock Input (MCU/FPGA) [0.1uF Capacitor] placed between Pin 14 and Pin 7 for noise decoupling. ```
