The **MHO323TAD-R** is a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. It is specifically designed as a high-speed, high-stability timing component used in telecommunications and data processing. --- ### 1. Technical Specifications The following table highlights the core electrical characteristics typical of the MHO323 series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Fixed Frequency Crystal Oscillator (XO) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage (Vcc)** | 3.3V or 5.0V (Standard 3.3V for 'TAD' suffix) | | **Package Style** | 14-pin DIP (DIP-14) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±20ppm to ±100ppm (depending on specific sub-code) | | **Mounting Type** | Through-Hole | --- ### 2. Key Features and Design The MHO323TAD-R is built to provide a reliable clock source for digital circuits. Its architecture focuses on the following: * **DIP-14 Package:** It utilizes a full-size metal "can" package with 4 active pins, providing excellent EMI (Electromagnetic Interference) shielding. * **Tri-state Functionality:** The "T" in the part number often indicates a **Tri-state (Enable/Disable)** function. This allows the output to be placed in a high-impedance state, which is useful for testing or power saving. * **RoHS Compliant:** The "-R" suffix denotes that the part is Lead-Free and compliant with the Restriction of Hazardous Substances directive. * **High Driving Capability:** Capable of driving multiple CMOS loads without significant signal degradation. --- ### 3. Pin Configuration For a standard MHO series oscillator in a DIP-14 footprint, the pinout is generally as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-state | Leave open or pull high for output; pull low to disable. | | **7** | Ground | Circuit and Case Ground. | | **8** | Output | The generated square wave frequency. | | **14** | Vcc | Positive Supply Voltage. | --- ### 4. Typical Applications This component is commonly found in industrial-grade hardware where through-hole mounting is preferred for durability or legacy support: * **Networking Gear:** Switches, routers, and hubs. * **Industrial Controllers:** PLC units and automated timing systems. * **Embedded Systems:** Microcontrollers requiring a precise external clock source.
