The **MHO+17TGG-R** is a specific part number typically associated with **Quartz Crystal Oscillators**, often manufactured by companies like MtronPTI. These components are essential in electronics for providing a stable clock signal. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Full size) or 8-pin DIP (Half size) | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | 5.0V (Standard for MHO series) | | **Frequency Stability** | ±100 ppm (Typical for '17' code) | | **Operating Temperature** | 0°C to +70°C (Commercial Grade) | | **RoHS Status** | Compliant (Indicated by "-R") | --- ### 2. Pin Configuration For a standard 14-pin DIP package (though only 4 pins are usually used): | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / Tri-state | No connection or Output Enable/Disable | | **7** | GND | Ground connection | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | Power supply (+5.0V) | --- ### 3. Key Electronic Features #### **A. HCMOS/TTL Compatibility** The "T" in the part number often signifies TTL compatibility. This means the output signal levels are designed to drive logic circuits that operate on standard Transistor-Transistor Logic or High-speed CMOS thresholds. #### **B. Through-Hole Mounting** Unlike modern SMD (Surface Mount Device) components, the MHO series uses pins that go through the PCB. This makes it ideal for: * Legacy hardware repairs. * Industrial equipment with high vibration resistance requirements. * Prototyping on breadboards or perf-boards. #### **C. Frequency Generation** The "G" suffix usually refers to the specific frequency or symmetry requirements. While the base part number defines the series, the full label on the physical component will include a numerical value (e.g., 10.000 MHz) indicating its oscillation speed. --- ### 4. Common Applications * **Microprocessor Clocks:** Providing the heartbeat for CPUs and MCUs. * **Networking Equipment:** Timing for data packets in routers and switches. * **Industrial Controllers:** Ensuring synchronized operations in PLC systems. * **Test & Measurement:** Used in frequency counters and signal generators.
