The **MHO+68FAAD-R** refers to a high-performance **Crystal Oscillator (XO)**, typically manufactured by companies like **MtronPTI**. This specific part belongs to a family of frequency control devices used in telecommunications, networking, and industrial computing. --- ### 1. Technical Specifications Table Below are the typical technical parameters associated with this specific series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Quartz Crystal Oscillator (Fixed Frequency) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage ($V_{cc}$)** | +5.0 VDC | | **Frequency Range** | 1.000 MHz to 100.000 MHz (Part specific) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Stability** | ±100 ppm (standard) | | **RoHS Status** | "R" suffix indicates RoHS Compliant | --- ### 2. Breakdown of Part Number Nomenclature While manufacturers vary slightly, the "MHO" series code usually breaks down as follows: * **MHO:** Identifies the product series (5.0V Full Size DIP Oscillator). * **+:** Usually indicates a lead-free/RoHS compliant process. * **68:** Often refers to the frequency stability or specific temperature range (e.g., ±50ppm or ±100ppm). * **F:** Frequently denotes the symmetry or duty cycle requirements (e.g., 45/55%). * **AA:** Internal factory codes or specific output load requirements. * **D:** Pinout configuration (Standard 4-pin connection within a 14-pin footprint). * **-R:** Indicates **RoHS Compliant** (Restriction of Hazardous Substances). --- ### 3. Key Features & Applications #### Key Features * **Reliability:** High resistance to mechanical shock and vibration. * **Output:** High-speed CMOS/TTL driving capability suitable for clocking microprocessors. * **Form Factor:** The 14-pin DIP package is common for older industrial designs or systems requiring "Through-Hole" mounting for durability. #### Common Applications * **Networking:** Clocking for Routers, Hubs, and Switches. * **Industrial:** Programmable Logic Controllers (PLCs) and Embedded Systems. * **Legacy Hardware:** Repair and maintenance of older computing hardware that utilizes 5V logic. --- ### 4. Typical Pin Configuration (14-Pin DIP) Even though the package has 14 pins, only 4 are usually active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / Tri-state | No Connection or Output Enable | | **7** | GND | Case Ground / Negative Power | | **8** | Output | Frequency Signal Output | | **14** | $V_{cc}$ | +5.0V Power Supply | ---
