The **MHO+16TAG-R** belongs to a specific category of electronic components known as **Crystal Oscillators**. These are used to provide a precise clock frequency for microprocessors, digital signal processors (DSPs), and other logic circuits. Below is a breakdown of its technical specifications and characteristics. --- ### 1. Component Overview The "MHO" series is typically manufactured by **MtronPTI**. This specific part is a Thru-Hole Crystal Clock Oscillator. | Feature | Specification | | :--- | :--- | | **Part Number** | MHO+16TAG-R | | **Component Type** | XO (Standard Crystal Oscillator) | | **Package Type** | 14-pin DIP (Full Size) or 8-pin DIP (Half Size) Compatibility | | **Mounting Style** | Through-Hole | | **Output Type** | CMOS / TTL | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Part Number Deciphering The nomenclature of these oscillators usually follows a specific coding pattern: * **MHO:** The series prefix (High-speed CMOS/TTL compatible). * **+:** Often indicates a specific voltage or lead-free process enhancement. * **16:** This usually refers to the **Frequency** (16.000 MHz). * **T:** Temperature Stability/Range indicator. * **A:** Accuracy/Tolerance rating (e.g., ±100ppm or ±50ppm). * **G:** Duty Cycle / Symmetry specification (e.g., 40/60%). * **-R:** RoHS Compliant (Lead-free). --- ### 3. Pin Configuration For a standard 14-pin DIP package (though only 4 pins are physically present), the layout is typically: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No Connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated 16 MHz Square Wave | | **14** | Vcc | Power Supply (usually +5V or +3.3V) | --- ### 4. Key Technical Characteristics 1. **Frequency Stability:** These oscillators are far more stable than ceramic resonators, often maintaining accuracy within parts per million (PPM) over a wide temperature range. 2. **Logic Compatibility:** The "TAG" variants are designed to drive CMOS and TTL loads directly without additional buffering. 3. **Encapsulation:** It is housed in a hermetically sealed metal "can" to protect the quartz crystal from environmental interference and electromagnetic interference (EMI). ### 5. Common Applications * **Microcontrollers:** Providing the "heartbeat" for CPUs. * **Networking:** Timing for Ethernet controllers. * **Industrial:** Timing for PLC (Programmable Logic Controllers). * **Legacy Hardware:** Often found in older computer motherboards or arcade systems requiring a 16MHz clock.
