The **MHO+68FCG-R** is a high-precision, industrial-grade crystal oscillator. Specifically, it belongs to the **MHO+** series produced by **MtronPTI**, a leading manufacturer of frequency control and spectrum control products. --- ### 1. Component Overview This component is a **Clock Oscillator** designed for high-reliability applications. It converts DC power into a precise square-wave electrical signal used to synchronize the operations of digital circuits. ### 2. Technical Specifications The part number "MHO+68FCG-R" can be broken down into specific technical parameters: | Feature | Specification | Description | | :--- | :--- | :--- | | **Type** | Crystal Oscillator (XO) | Fixed frequency output. | | **Package** | 14-pin DIP (DIL) | Full-size metal plug-in package (often 4 pins active). | | **Output Type** | HCMOS / TTL | Compatible with high-speed CMOS and Transistor-Logic levels. | | **Voltage Supply** | 5.0V | Operates on a standard 5V rail. | | **Stability** | ±25ppm to ±100ppm | Varies by specific dash-code (generally high stability). | | **RoHS Status** | Compliant (-R) | The "R" suffix indicates Lead-Free/RoHS compliance. | --- ### 3. Key Electronic Characteristics * **Tri-state Function:** Most MHO+ series oscillators include an enable/disable function (Pin 1), allowing the output to enter a high-impedance state to save power or perform testing. * **Hermetic Sealing:** The metal casing is resistance-welded to protect the internal quartz crystal from moisture and atmospheric contaminants, ensuring long-term frequency aging stability. * **Low Jitter:** Designed for timing-critical applications where "phase noise" or "jitter" must be minimized to prevent data errors. ### 4. Common Applications Due to its robust metal packaging and 5V operation, this part is typically found in: * **Industrial Control Systems:** PLC units and factory automation. * **Legacy Computing:** Older motherboard designs or embedded systems requiring 5V logic. * **Telecommunications:** Network hubs and transmission equipment. * **Test & Measurement:** Oscilloscopes and signal generators. --- ### 5. Pinout Configuration (Standard 14-pin DIP) While the package has 14 pins, usually only 4 are electrically functional: | Pin Number | Function | | :--- | :--- | | **1** | NC or Tri-state Enable | | **7** | Ground (Case) | | **8** | Output Signal | | **14** | Vcc (+5.0V) | ---
