The **MHO+14TCG-R** is a specific part number for a high-performance **Crystal Oscillator**. These components are essential in electronics for providing a stable clock signal to microprocessors, telecommunications equipment, and digital circuits. ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | Active timing device | | **Package / Case** | 14-pin DIP (Full Size) | Through-hole metal rectangular package | | **Output Type** | HCMOS / TTL | Compatible with standard digital logic levels | | **Voltage Supply** | 5.0V (Typical) | Standard operating voltage for "MHO" series | | **Frequency Range** | Varies | Depends on the specific frequency stamped on the casing | | **RoHS Status** | Compliant (-R suffix) | Lead-free and environmentally friendly | --- ### 2. Key Internal Components The "MHO" series typically consists of three primary internal elements: 1. **Quartz Crystal Blank:** A precision-cut piece of quartz that vibrates at a specific frequency when an electric field is applied (Piezoelectric effect). 2. **Oscillator IC:** An integrated circuit that sustains the oscillation and converts the mechanical vibration into a clean square wave. 3. **Bypass Capacitor:** Internal filtering to reduce electrical noise on the power supply line. --- ### 3. Pin Configuration (14-pin DIP Standard) Although it uses a 14-pin footprint, most of the pins are removed or unused. The standard pinout for this series is: * **Pin 1:** NC (No Connection) or Tri-state Control (Enable/Disable). * **Pin 7:** Case Ground (GND). * **Pin 8:** Output (The clock signal). * **Pin 14:** Vcc (+5V Power Supply). --- ### 4. Applications The MHO+14TCG-R is commonly found in: * **Legacy Computing:** Motherboards and peripheral cards. * **Industrial Control:** Timing for PLC (Programmable Logic Controllers). * **Networking:** Synchronizing data transmission in routers and switches. * **Test Equipment:** Providing a stable reference frequency for oscilloscopes or signal generators.
