The **MHO+52FGG-R** is a specific type of **Crystal Oscillator** manufactured by MtronPTI. It is a high-precision frequency control component used to provide a stable clock signal for electronic circuits. --- ### 1. Key Specifications Based on the part numbering system for the MHO series, here are the technical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Full Size) - Often 4 pins connected | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage** | +5.0 VDC | | **Stability** | Generally ±50 ppm or ±100 ppm (depending on suffix) | | **Operating Temperature** | 0°C to +70°C (Standard Commercial) | | **RoHS Status** | Compliant (Indicated by "-R") | --- ### 2. Breakdown of the Part Number To understand the electronic capabilities, we can deconstruct the code: * **MHO**: Represents the Series (Metal Thru-Hole Oscillator). * **+**: Usually denotes a specific lead-free/RoHS enhancement or a custom variation. * **5**: Indicates the voltage rating (5V). * **2**: Often indicates the stability/temperature coefficient (e.g., ±50ppm). * **F**: Frequency stability/Output symmetry code (typically 45/55% duty cycle). * **GG**: Specific internal code for package/pinout configuration. * **R**: **RoHS Compliant**. This ensures the part is manufactured without lead or other hazardous substances. --- ### 3. Internal Components & Operation Inside the metal "can" of the MHO+52FGG-R, there are several key electronic elements: 1. **Quartz Crystal Slice**: The "heart" of the component that vibrates at a specific frequency via the piezoelectric effect. 2. **Oscillator IC**: A small silicon chip that provides the necessary gain to maintain oscillation and buffers the output signal. 3. **Bypass Capacitor**: Internal capacitance to filter noise from the DC power supply. 4. **Hermetic Seal**: The metal housing is filled with an inert gas (like Nitrogen) to prevent the quartz from oxidizing, ensuring long-term frequency stability. --- ### 4. Typical Pin Configuration For a standard 14-pin DIP footprint (where only 4 pins are active): | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | +5V Power Supply | --- ### 5. Common Applications * **Microprocessors**: Providing the master clock for CPUs. * **Networking**: Synchronization in Ethernet or switching hardware. * **Industrial Control**: Timing for PLC (Programmable Logic Controllers). * **Legacy Systems**: Often found in older computing hardware or high-reliability industrial boards that require through-hole mounting.
