The **MHO+63TGD-R** is a specific series of high-precision crystal oscillators manufactured by **MtronPTI**. These components are critical for providing accurate timing signals in high-reliability electronic systems. ### 1. Technical Specifications Overview The part number follows a specific nomenclature that defines its electronic characteristics: | Feature | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Half Size | | **Output Type** | HCMOS / TTL Compatible | | **Voltage Supply** | Typically 5.0V (Standard for MHO+ series) | | **Operating Temp** | Industrial ranges available (Standard: 0°C to +70°C) | | **RoHS Status** | Compliant (indicated by the suffix/series) | --- ### 2. Key Electronic Features #### A. Tri-State Functionality The **"T"** in the part number usually signifies **Tri-state** capability. This allows the output pin to be placed in a high-impedance state, effectively disconnecting it from the circuit. This is useful for: * Power saving. * Automated board testing (ICT). * Bus-sharing architectures. #### B. Stability and Precision As an "MHO" series device, it is designed for tight frequency stability. It uses a quartz crystal resonator combined with a CMOS integrated circuit to maintain a consistent frequency despite fluctuations in temperature or voltage. #### C. Robust Construction The "R" suffix often denotes **RoHS compliance** (Lead-free), and the physical housing is a hermetically sealed metal can. This protects the internal quartz crystal from moisture and atmospheric contaminants, ensuring long-term frequency aging stability. --- ### 3. Pin Configuration (Typical 14-pin Half-DIP) Although it has a 14-pin footprint, only four pins are typically functional: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable (Tri-state control) or No Connection | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square wave) | | **14** | Vcc | Positive Power Supply (+5.0V) | --- ### 4. Common Applications Due to its reliability and standard footprint, it is frequently used in: 1. **Telecommunications:** Base stations and switching equipment. 2. **Industrial Control:** PLCs and synchronized manufacturing hardware. 3. **Legacy Computing:** Motherboards or expansion cards requiring a stable 5V clock source. 4. **Test & Measurement:** Oscilloscopes and signal generators.
