The **MHO362TCG-R** is a high-precision, surface-mount (SMD) electronic component, specifically classified as a **TCXO (Temperature Compensated Crystal Oscillator)**. It is manufactured by companies like Mercury Electronic and is designed for applications requiring high frequency stability over a wide temperature range. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Frequency Range** | Typically 10.000 MHz to 52.000 MHz (Commonly 26MHz) | | **Supply Voltage (Vcc)** | +1.8V to +3.3V DC (Variation dependent) | | **Output Type** | Clipped Sine Wave | | **Frequency Stability** | ±0.5 ppm to ±2.5 ppm (vs. Temperature) | | **Operating Temp** | -30°C to +85°C (Standard Industrial) | | **Package Size** | 3.2 x 2.5 x 1.0 mm (4 pads) | --- ### 2. Functional Components The MHO362TCG-R is not a simple quartz crystal; it is an integrated module containing several internal electronic parts: 1. **Quartz Crystal Resonator:** The primary mechanical element that vibrates at a specific frequency. 2. **Compensation Network:** A specialized analog circuit (often using thermistors or a digital compensation IC) that adjusts the capacitance to counteract frequency drift caused by temperature changes. 3. **Oscillator IC:** An active circuit that maintains the vibration of the crystal and converts it into an electrical signal. 4. **Voltage Regulator (Internal):** Ensures the internal oscillator remains stable even if the input supply voltage fluctuates slightly. --- ### 3. Pin Configuration (4-Pad SMD) | Pad Number | Function | Description | | :--- | :--- | :--- | | **1** | Vcon / NC | Voltage Control (for VCTCXO) or No Connection | | **2** | GND | Ground / Case Ground | | **3** | Output | The generated clock signal (Clipped Sine) | | **4** | Vdd | Power Supply Input | --- ### 4. Applications Because of its small footprint and high stability, this part is used in: * **GPS/GNSS Modules:** Precise timing is required to calculate location. * **Wireless Communication:** WiFi, Bluetooth, and LTE modules. * **IoT Devices:** Low power consumption and stability are critical for remote sensors. * **Smartphones:** Used as a reference clock for RF transceivers. ---
