The **MHO+76FBD-R** refers to a high-precision, high-frequency crystal oscillator, typically manufactured by companies like **MtronPTI**. These components are critical in telecommunications and data processing for providing a stable clock signal. --- ### 1. General Specifications The part number follows a specific nomenclature that defines its electrical and physical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage** | Typically 5.0V or 3.3V (Varies by sub-series) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full Size | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±100ppm to ±25ppm (depending on suffix) | --- ### 2. Key Internal Components An oscillator of this type is not just a crystal; it is an integrated circuit module consisting of: 1. **Quartz Crystal Resonator:** The heart of the part, cut at a specific angle (usually AT-cut) to vibrate at the target frequency. 2. **Oscillator IC:** An internal circuit that maintains the oscillation of the crystal and converts the mechanical vibration into an electrical square wave. 3. **Bypass Capacitor:** Built-in capacitance to filter power supply noise and ensure signal integrity. 4. **Hermetic Seal:** The metal "can" package is resistance-welded to protect the internal quartz from moisture and aging. --- ### 3. Pin Configuration (14-Pin DIP Layout) Although it has a 14-pin footprint, most pins are usually omitted, leaving only 4 functional pins: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or E/D | No Connection or Output Enable/Disable | | **7** | GND | Case Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | Positive Power Supply | --- ### 4. Application Areas The **MHO series** is known for its reliability in "legacy" or "through-hole" PCB designs. Common uses include: * **Networking Hardware:** Routers, switches, and hubs. * **Industrial Control:** PLCs and timing modules. * **Legacy Computing:** Motherboards or expansion cards requiring a stable 14-pin DIP clock source. --- ### 5. Part Number Breakdown (Typical) * **MHO:** Series designation (MtronPTI High-speed Oscillator). * **7:** Voltage/Package identifier (Full size 14-pin DIP). * **6:** Temperature range indicator. * **FBD:** Specific frequency stability and duty cycle code. * **-R:** RoHS Compliant (Lead-free).
