The **MHO+68FGG-R** is a specific part number typically associated with **MHO+ series High-Frequency Crystal Oscillators** manufactured by providers like MtronPTI. These components are critical for timing and frequency control in telecommunications and data processing hardware. --- ### 1. Component Specification Overview The "MHO" series generally refers to metal-can, through-hole (DIP) crystal oscillators. Below are the typical technical characteristics associated with this part number: | Parameter | Typical Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (or 4-pin equivalent metal can) | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | Usually 5.0V (Standard for MHO+ series) | | **Frequency Range** | Fixed frequency (defined by the specific suffix) | | **Temperature Range** | Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) | --- ### 2. Breakdown of the Part Number While specific manufacturer codes can vary slightly, the nomenclature generally breaks down as follows: * **MHO+**: Series identifier (High-speed, 5.0V logic, through-hole package). * **6**: Often denotes the frequency stability (e.g., ±50ppm or ±100ppm). * **8**: Typically represents the duty cycle or symmetry requirements. * **F**: Temperature range code (Often signifies Commercial or Industrial). * **GG**: Package or output configuration code. * **-R**: **RoHS Compliant**. This indicates the part is lead-free and meets environmental safety standards. --- ### 3. Key Electronic Functions The MHO+68FGG-R performs three primary functions within a circuit: 1. **Clock Generation**: It provides the "heartbeat" for microprocessors, FPGAs, and Ethernet controllers. 2. **Signal Conditioning**: It converts mechanical vibrations from a quartz crystal into a stable square-wave electrical signal (HCMOS/TTL). 3. **EMI Shielding**: Because it is housed in a metal "DIP" package, it offers superior protection against Electromagnetic Interference (EMI) compared to some plastic-molded oscillators. --- ### 4. Typical Applications * **Networking Hardware**: Hubs, routers, and switches. * **Industrial Control**: PLCs (Programmable Logic Controllers). * **Legacy Computing**: Industrial PCs using through-hole PCB designs. * **Test & Measurement**: Signal generators and frequency counters. --- ### 5. Circuit Connection Example When integrating this part, the pinout typically follows the industry-standard 14-pin DIP footprint: ```markdown Pin 1: NC (No Connection) or Tri-state Enable Pin 7: Ground (GND) Pin 8: Output (Clock Signal) Pin 14: Vcc (+5.0V) ```
