The **MHO+65FBD-R** is a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. It belongs to the MHO series, which is known for providing stable timing signals in a standard 14-pin DIP (Dual In-line Package) footprint. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (Fixed Frequency) | | **Package Style** | 14-pin DIP (Full Size) | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | 5.0 VDC | | **Stability** | ±100 ppm (Standard for the "F" suffix) | | **Temperature Range** | 0°C to +70°C (Commercial Grade) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown Understanding the alphanumeric code helps identify the specific electronic characteristics: * **MHO:** Series designation (MtronPTI High-Output/Standard series). * **+:** Usually indicates a specific lead-free or enhanced manufacturing process. * **6:** Voltage rating (typically representing 5.0V). * **5:** Symmetry/Duty Cycle (typically 40/60% or 45/55%). * **F:** Frequency Stability (F usually denotes ±100ppm). * **B:** Operating Temperature Range (B usually denotes 0°C to +70°C). * **D:** Tri-state Enable/Disable function (Pin 1). * **-R:** RoHS Compliant (Lead-free). --- ### 3. Functional Pinout Although it fits a 14-pin footprint, most oscillators of this type only utilize 4 active pins: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Tri-State / NC | Logic high or floating allows output; Logic low disables output. | | **7** | Case Ground | Connected to the metal cover for EMI shielding. | | **8** | Output | The generated clock signal (Square Wave). | | **14** | Vcc | +5.0V Power Supply. | --- ### 4. Typical Applications This component is used to provide a "heartbeat" or clock reference for digital circuits, including: * **Microprocessors:** Driving the system clock for legacy computing hardware. * **Industrial Controllers:** Timing for PLCs and automation equipment. * **Networking:** Syncing data transmission in older Ethernet or serial communication hardware. * **Test & Measurement:** Providing stable references for frequency counters.
