The **MHO+74FCG-R** is a specific part number for a high-performance **Crystal Oscillator** (XO) manufactured by **MtronPTI**. These components are critical in electronics for generating a precise, stable clock signal used to synchronize data and operations. --- ### 1. Key Technical Specifications Based on the part numbering convention for the MHO series, here are the primary technical characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | A complete timing solution with integrated crystal and circuitry. | | **Output Type** | CMOS / TTL | Provides a standard digital square wave output. | | **Voltage Supply** | 5.0V (Standard) | Operates on a typical 5V DC power rail. | | **Frequency Range** | 1.0 MHz to 150 MHz | The specific frequency is usually stamped on the physical unit. | | **Package Style** | 14-pin DIP (Half Size) | A "Full Size" or "Half Size" metal can through-hole package. | | **Stability** | ±100 ppm (Typical) | Frequency stability over the operating temperature range. | | **RoHS Status** | Compliant (-R) | The "R" suffix indicates Lead-Free/RoHS compliance. | --- ### 2. Breakdown of Part Number (MHO+74FCG-R) * **MHO:** Series designation (MtronPTI High-Reliability Oscillators). * **7:** Refers to the Operating Voltage (typically 5V for this series). * **4:** Stability code (indicates frequency tolerance over temperature). * **F:** Fixed Frequency (as opposed to voltage-controlled). * **C:** Commercial Temperature Range (0°C to +70°C). * **G:** Symmetry/Duty Cycle (typically 40/60% or 45/55%). * **-R:** RoHS Compliant (Environmentally friendly materials). --- ### 3. Common Applications These oscillators are designed for "Mission Critical" or high-reliability industrial environments. Common uses include: 1. **Microprocessors:** Providing the main clock pulse for CPU execution. 2. **Networking:** Synchronizing data packets in Ethernet or Fiber switches. 3. **Industrial Controls:** Used in PLCs and automation hardware where 5V logic is common. 4. **Legacy Systems:** Often used as a high-quality replacement for older timing components in telecommunications. --- ### 4. Typical Pin Configuration The MHO series in a 14-pin through-hole package usually utilizes only 4 pins: | Pin Number | Function | | :--- | :--- | | **Pin 1** | N/C or Tri-state (Enable/Disable) | | **Pin 7** | Case Ground (GND) | | **Pin 8** | Output Signal (Clock) | | **Pin 14** | Supply Voltage (Vcc) |
