The **MHO+64FBG-R** refers to a high-performance integrated circuit, typically associated with specialized clock oscillators or frequency control components, often manufactured by companies like **MtronPTI**. Below is a technical breakdown of its electronic characteristics and construction. --- ### 1. Technical Specifications The part belongs to the **MHO+ series**, which are typically High-Reliability (Hi-Rel) Crystal Oscillators. | Feature | Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Full Size | | **Frequency Range** | Typically fixed (range varies by specific sub-model) | | **Output Type** | CMOS/TTL Compatible | | **Input Voltage** | +5.0V DC (Standard for the MHO series) | | **Operating Temperature** | Often -40°C to +85°C (Industrial Grade) | | **Feature Suffix (-R)** | Denotes RoHS Compliance (Lead-Free) | --- ### 2. Key Internal Components The "MHO" series is built using several internal electronic stages: * **Quartz Crystal Resonator:** The heart of the part, providing the stable reference frequency. * **Oscillator IC:** An internal integrated circuit that maintains the vibration of the crystal and converts it into a square wave. * **Compensation Network:** Internal capacitors and resistors used to stabilize the frequency against temperature fluctuations. * **Output Buffer:** Ensures the signal is strong enough to drive downstream digital logic (TTL or CMOS) without signal degradation. --- ### 3. Pin Configuration (Typical 14-Pin DIP) While the physical package is a 14-pin rectangle, usually only 4 pins are electrically connected: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit ground | | **8** | Output | The generated clock signal (Square wave) | | **14** | Vcc | +5.0V Power Supply | --- ### 4. Application Use Cases Because of its "Metal Can" (DIP) form factor and high reliability, this part is commonly used in: 1. **Legacy Computing:** Replacement parts for older industrial motherboards. 2. **Telecommunications:** Timing synchronization in base stations. 3. **Aerospace/Defense:** Robustness against EMI (Electromagnetic Interference) due to the grounded metal casing. 4. **Test Equipment:** Stable clock sources for oscilloscopes and signal generators. --- ### 5. Part Number Decoding * **MHO:** Series Prefix (MtronPTI High-Reliability Oscillator). * **+:** Usually indicates a specific voltage or internal revision. * **64:** Often relates to the frequency (e.g., 64.000 MHz) or a specific stability code. * **FBG:** Specific package/output logic configuration (Standard CMOS, 45/55 symmetry). * **-R:** **RoHS Compliant** (Restricted Hazardous Substances).
