Based on the part number **MHO+75TBD-R**, this component is a high-precision **Crystal Oscillator** typically manufactured by **MtronPTI**. These parts are commonly used in telecommunications and data processing where stable clock signals are required. --- ### 1. Key Technical Specifications | Feature | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Half Size | | **Voltage Supply** | Typically 5.0V or 3.3V (Model dependent) | | **Output Type** | HCMOS / TTL Compatible | | **Frequency Range** | Usually ranges from 1.0 MHz to 150.0 MHz | | **Operating Temperature** | Often -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number The alphanumeric string follows a specific coding logic used by MtronPTI: * **MHO:** Series designation (Metal Half-size Oscillator). * **+:** Usually indicates a lead-free/RoHS compliant design. * **75:** This code typically refers to the **Frequency Stability**. In many Mtron series, "7" or "5" combined indicates ±50ppm or ±100ppm stability over the temperature range. * **T:** Denotes the **Temperature Range**. "T" usually stands for the industrial range (-40°C to +85°C). * **B:** Refers to the **Duty Cycle** (typically 40/60% or 45/55%). * **D:** Refers to the **Voltage Supply** (D is often a code for 3.3V). * **-R:** Confirms **RoHS Compliance**. --- ### 3. Physical Characteristics and Pinout The "Half-size DIP" package is a 4-pin metal can that fits into a standard 14-pin DIP footprint, occupying only half the length. #### Common Pin Configuration: ```text Pin 1: NC (No Connection) or Tristate/Enable Pin 7: Case Ground Pin 8: Output Signal Pin 14: Vcc (Power Supply) ``` --- ### 4. Typical Applications * **Networking:** Routers, switches, and fiber-optic modules. * **Embedded Systems:** Providing a stable master clock for Microcontrollers and FPGAs. * **Industrial Control:** High-reliability timing in harsh environments. * **Legacy Systems:** Maintenance of older hardware using through-hole technology.
