The **MHO367TCD-R** is a specific surface-mount electronic component, typically categorized as a **Temperature Compensated Crystal Oscillator (TCXO)** or a high-precision oscillator module. These parts are vital for providing a stable clock signal in RF (Radio Frequency) and telecommunications equipment. --- ### 1. Key Technical Specifications Based on standard industry naming conventions for the MHO series, here are the likely electronic characteristics: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Output Type** | CMOS / Clipped Sine Wave | | **Supply Voltage (Vcc)** | 3.3V or 5.0V (Model dependent) | | **Package Style** | SMD (Surface Mount Device) | | **Frequency Stability** | ±0.5ppm to ±2.5ppm (Over temp range) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | --- ### 2. Functional Breakdown The "TCXO" designation means the part contains internal circuitry to counteract the natural frequency drift of a quartz crystal caused by temperature changes. * **Quartz Crystal:** The core vibrating element that sets the base frequency. * **Compensation Network:** A temperature sensor and a varactor diode that adjusts the load capacitance to keep the frequency constant. * **Buffer/Output Stage:** Ensures the signal is strong enough to drive other digital components (like microcontrollers or FPGAs) without distorting. --- ### 3. Applications The MHO367TCD-R is designed for environments where timing precision is critical even as the device heats up or cools down. Common uses include: * **GPS Receivers:** Fast satellite signal acquisition requires tight frequency tolerance. * **Base Stations:** Synchronizing data packets in cellular networks (4G/5G). * **Wi-Fi Routers:** Maintaining stable wireless carrier frequencies. * **IoT Modules:** Reliable long-range communication (LoRa, Sigfox). --- ### 4. Part Number Breakdown (General Identification) While specific to the manufacturer (often associated with brands like **Mercury Electronic**), the suffix codes usually represent: * **MHO:** Series designation (High-stability oscillators). * **367:** Package size/series code (e.g., 7.0 x 5.0 mm or 5.0 x 3.2 mm). * **TCD:** Temperature range and stability classification. * **-R:** RoHS Compliant (Lead-free). ---
