Based on the technical nomenclature, the **MHO367TAD-R** refers to a high-precision **TCXO (Temperature Compensated Crystal Oscillator)**. These components are critical in telecommunications and navigation systems where frequency stability is paramount. --- ## 1. Core Technical Specifications The part belongs to a class of surface-mount oscillators designed to maintain a consistent output frequency despite fluctuations in environmental temperature. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Package Type** | SMD (Surface Mount Device) | | **Output Type** | Usually Clipped Sine Wave or CMOS | | **Standard Frequency** | Commonly 10.000 MHz to 40.000 MHz (Model dependent) | | **Supply Voltage** | 3.3V (Typical for "TAD" series) | | **Frequency Stability** | ±0.5 ppm to ±2.5 ppm | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ## 2. Key Electronic Characteristics ### Frequency Stability Unlike standard quartz crystals, the "T" in the part number indicates **Temperature Compensation**. It contains an internal thermistor and compensation circuit that adjusts the load capacitance of the crystal to counteract the drift caused by temperature changes. ### Phase Noise and Jitter The MHO series is generally optimized for low phase noise, which is essential for: * Minimizing bit error rates in data transmission. * Improving signal-to-noise ratios in RF applications. ### Power Consumption As an active component, it requires a stable DC power supply (Vcc). The "-R" suffix often denotes **RoHS Compliance**, meaning it is manufactured without hazardous substances like lead. --- ## 3. Pinout and Integration While specific datasheets can vary by manufacturer (often produced by companies like **Mercury Electronic**), the standard pin configuration for this footprint is typically: ```text Pin 1: Vc (Voltage Control) or NC (No Connection) Pin 2: GND (Ground) Pin 3: Output (Frequency Signal) Pin 4: Vcc (Supply Voltage) ``` --- ## 4. Typical Applications 1. **GPS/GNSS Receivers:** Providing the precise timing needed to calculate positioning. 2. **Wireless Communication:** Base stations, Wi-Fi modules, and LTE equipment. 3. **IoT Devices:** Low-power wide-area networks (LPWAN) requiring stable clocks for long-range communication.
