The **MHO+66FCG-R** is a high-performance **Crystal Oscillator** manufactured by MtronPTI. This specific component belongs to the MHO+ series, which is known for its reliability in industrial and communication applications. --- ### 1. Key Technical Specifications Below is a detailed breakdown of the technical characteristics typically associated with this part number: | Feature | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Output Type** | CMOS / TTL Compatible | | **Package Style** | 14-pin DIP (Full Size) | | **Frequency Stability** | ±100 ppm (standard for this series) | | **Operating Voltage** | 5.0 V DC | | **Temperature Range** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying the exact variant of the electronic part: * **MHO:** Series designation (MtronPTI High-Reliability Oscillators). * **+:** Indicates a lead-free/RoHS compliant version of the base series. * **66:** Represents the specific stability and temperature coefficient (usually 100ppm over industrial range). * **F:** Frequency Control / Tri-state function (allows the output to be disabled/disconnected). * **CG:** Package/Pin configuration code. * **-R:** RoHS Compliant. --- ### 3. Functional Description The MHO+66FCG-R is an active component that generates a precise square wave signal used as a heartbeat for digital circuits. #### A. Tri-State Function The "F" in the part number indicates a **Tri-state Enable/Disable** function. When the enable pin is pulled low, the output goes into a high-impedance state. This is useful for: * Power saving during standby modes. * System testing and automated troubleshooting. #### B. Thru-Hole Mounting Unlike modern surface-mount (SMD) components, this part uses the **14-pin DIP** format. While it only uses four physical pins (Power, Ground, Output, and Enable), the large metal "can" package provides excellent electromagnetic interference (EMI) shielding. --- ### 4. Common Applications * **Networking Gear:** Used in routers and switches for timing synchronization. * **Industrial Controllers:** Providing clock signals for PLCs and ruggedized computers. * **Legacy Systems:** Maintenance and repair of older telecommunication hardware that utilizes DIP sockets. * **Medical Equipment:** Where stable frequency generation in a shielded package is required.
