The **MHO+76TGD-R** is a specific part number for a high-performance **Crystal Oscillator (XO)** manufactured by **MtronPTI**. These components are critical for providing stable timing signals in telecommunications, aerospace, and high-speed networking equipment. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature. Below are the primary technical characteristics associated with this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | CMOS / TTL | | **Voltage Supply** | 5.0V (Standard for MHO series) | | **Package Style** | 14-pin DIP (Full-size) or 8-pin DIP (Half-size) | | **Frequency Range** | 1.0 MHz to 150.0 MHz (Depends on specific sub-code) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Stability** | ±100ppm to ±25ppm (Defined by the "76" code) | --- ### 2. Breakdown of the Part Number While internal manufacturer codes can vary slightly, the "MHO" series generally breaks down as follows: * **MHO:** Series designation (Metal Hermetic Oscillator). * **7:** Indicates the voltage and package type (usually 5.0V, Full-size 14-pin DIP). * **6:** Specifies the frequency stability (e.g., ±25ppm). * **T:** Temperature range (T often denotes extended/industrial range: -40°C to +85°C). * **G:** Duty Cycle / Symmetry requirement (typically 40/60% or 45/55%). * **D:** Tri-state Enable/Disable function (allows the output to be turned off for testing). * **R:** RoHS Compliant (Lead-free). --- ### 3. Application and Usage Because this is a **Through-Hole (DIP)** component rather than an SMT (Surface Mount) device, it is typically found in: * **Legacy Systems:** Maintenance and repair of older industrial controllers. * **Prototyping:** Easier to use on breadboards or through-hole PCBs. * **High-Reliability Gear:** The hermetically sealed metal package provides excellent protection against electromagnetic interference (EMI). ### 4. Comparison with Modern Alternatives | Feature | MHO+76TGD-R (DIP) | Modern SMT (e.g., 7050 size) | | :--- | :--- | :--- | | **Mounting** | Through-hole (requires drilling) | Surface Mount (pick-and-place) | | **Size** | Large (approx. 20mm x 13mm) | Small (approx. 7mm x 5mm) | | **Durability** | High (Metal Casing) | Moderate (Ceramic Casing) | | **Availability** | Often specialized/Legacy | Mass-market | ---
