The **MHO+56TGG-R** is a specific part number belonging to a series of high-performance **Clock Oscillators** (Crystal Oscillators) manufactured by **MtronPTI**. These components are used to provide a stable frequency reference for digital circuits, microprocessors, and telecommunications equipment. --- ### 1. Key Technical Specifications Based on the standard nomenclature for the MHO series, here are the primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Fixed Frequency Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (DIL) - Often 4 pins connected | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage (Vcc)** | 5.0 Volts (Standard for the "5" prefix) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | Typically ±100ppm, ±50ppm, or ±25ppm (depending on grade) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number To understand the specific capabilities, we can decode the alphanumeric string: * **MHO:** Identifies the product series (Metal package, HCMOS/TTL output). * **+:** Usually indicates a specific lead-free or enhanced version. * **5:** Represents the operating voltage (5.0V). * **6:** Often refers to the frequency stability or temperature range (check specific datasheet as this varies by manufacturer revision). * **T:** Denotes "Tight" stability or specific symmetry requirements. * **GG:** These codes typically refer to the specific operating temperature range and output load. * **-R:** Indicates **RoHS Compliance** (Lead-free). --- ### 3. Physical Construction and Pins The MHO series typically uses a hermetically sealed metal "can" to protect the quartz crystal from environmental interference and electromagnetic interference (EMI). | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | NC or Tri-state | No connection or Output Enable/Disable | | **Pin 7** | GND | Circuit Ground | | **Pin 8** | Output | The generated clock signal (Square wave) | | **Pin 14** | Vcc | +5.0V Power Supply | --- ### 4. Common Applications * **Networking:** Routers, switches, and modems. * **Industrial Control:** Embedded systems requiring a steady 5V clock source. * **Legacy Computing:** Replacement parts for older motherboards or timing circuits that operate on 5V logic. * **Test & Measurement:** Oscilloscopes and signal generators. ---
