The **MHO+55TFG-R** is a specific series of high-precision crystal oscillators manufactured by **MtronPTI**. These components are widely used in telecommunications and aerospace applications due to their stability and reliability. ### 1. Key Technical Specifications Below are the general electronic characteristics associated with the MHO series (Standard 14-pin DIP package configuration): | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | HCMOS/TTL Compatible | | **Supply Voltage ($V_{cc}$)** | Typically 5.0V (Standard for MHO series) | | **Frequency Range** | 1.000 MHz to 100.000 MHz (Model dependent) | | **Package Style** | 14-pin DIP (Full size) Metal Can | | **Operating Temperature** | -40°C to +85°C (Standard Industrial) | --- ### 2. Part Number Breakdown The nomenclature for MtronPTI parts identifies specific electronic traits: * **MHO:** Series designation (Metal Hermetic Oscillator). * **+:** Denotes RoHS compliance (Lead-free). * **5:** Usually refers to the supply voltage (e.g., 5.0V). * **5:** Refers to the stability (e.g., ±50ppm). * **T:** Temperature range code (e.g., -40°C to +85°C). * **F:** Frequency stability / Symmetry code. * **G:** Enable/Disable function (Tristate) on Pin 1. * **-R:** RoHS compliant version. --- ### 3. Pin Configuration (14-pin DIP) The electronic interface for this part follows a standard industry footprint for through-hole mounting: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | N/C or Tri-state | High = Enable; Low = High Impedance | | **Pin 7** | GND | Circuit Ground / Case Ground | | **Pin 8** | Output | Square wave frequency output | | **Pin 14** | $V_{cc}$ | Positive Supply Voltage (+5V) | --- ### 4. Application and Usage This part is an **active component**, meaning it generates a clock signal internally once power is applied. Unlike a simple crystal (passive), it does not require external capacitors or load matching. * **Clock Generation:** Provides the heartbeat for Microprocessors, DSPs, and FPGAs. * **Stability:** The metal hermetic seal protects the quartz crystal from environmental humidity and aging. * **Noise Performance:** Low phase jitter suitable for high-speed data transmission.
