The **MHO+36TCG-R** is a specific part number typically associated with **Temperature Compensated Crystal Oscillators (TCXOs)** manufactured by companies like **Mercury Electronic**. These components are critical for providing a highly stable frequency reference in electronic circuits. ### 1. Component Overview The part belongs to the **MHO+** series. These are high-performance oscillators designed to maintain frequency accuracy despite fluctuations in ambient temperature. | Feature | Description | | :--- | :--- | | **Component Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Package Type** | DIL-14 (Dual In-Line) or Rectangular Through-Hole | | **Mounting Style** | Through-Hole Technology (THT) | | **Primary Function** | Frequency Generation / Timing Reference | --- ### 2. Breakdown of the Part Number While specific manufacturer codes vary slightly, the nomenclature usually breaks down as follows: * **MHO+**: The series prefix, indicating a high-stability TCXO in a standard metal package. * **36**: Often refers to the supply voltage or a specific package dimension (e.g., 3.3V or 5.0V variants). * **TCG**: This represents the temperature stability and output type. * **TC**: Temperature Compensated. * **G**: Often denotes HCMOS/TTL compatibility or specific RoHS compliance. * **-R**: Generally indicates **RoHS Compliant** (Lead-free). --- ### 3. Key Electronic Specifications These oscillators are characterized by their precision compared to standard crystals or clock oscillators. 1. **Frequency Stability**: Typically ranges from **±1.0ppm to ±5.0ppm** across the operating temperature range. 2. **Output Waveform**: Usually **HCMOS/TTL**, making it directly compatible with microcontrollers and FPGAs. 3. **Supply Voltage**: Most modern versions operate at **3.3V or 5.0V DC**. 4. **Aging**: Low aging rates (e.g., ±1ppm per year), ensuring long-term reliability. --- ### 4. Typical Applications Because of its high stability, the MHO+36TCG-R is used in environments where frequency drift could cause system failure: * **Telecommunications**: Base stations and networking hardware. * **Radio Equipment**: Two-way radios and transceivers where channel spacing is tight. * **Test & Measurement**: Signal generators and frequency counters. * **GPS/Navigation**: Systems requiring precise time-stamping. --- ### 5. Pin Configuration (Typical DIL-14) For the 14-pin DIP style package (even if only 4 pins are physically present): | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Vcon / NC | Voltage Control (for VCTCXOs) or No Connection | | **7** | GND | Ground | | **8** | Output | The generated clock signal | | **14** | Vcc | Positive Supply Voltage |
