The **MHO315TAD-R** is a specific electronic component, typically categorized as a **Surface Mount (SMD) Crystal Oscillator**. These components are essential in digital electronics for providing a stable clock signal to microprocessors and communication systems. --- ### 1. Technical Specifications The following table outlines the general technical characteristics associated with this series: | Parameter | Typical Value / Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Frequency Stability** | ±25ppm to ±100ppm (varies by sub-grade) | | **Operating Voltage** | 3.3V or 5.0V (Standard) | | **Output Type** | HCMOS / TTL Compatible | | **Package Size** | 14-pin DIP compatible footprint (4-pin active) | | **Operating Temperature** | -10°C to +70°C (Standard Industrial) | --- ### 2. Key Electronic Features * **Tri-State Function:** The "T" in the part number often indicates a Tri-state (Enable/Disable) function. This allows the output to be disconnected electronically, which is useful for power saving or system testing. * **Hermetic Sealing:** These oscillators are usually housed in a metal seam-welded package to protect the quartz crystal from environmental moisture and aging. * **Low Phase Jitter:** Designed to provide a clean square wave with minimal timing deviations, ensuring stable data processing in high-speed circuits. * **Integrated IC:** Unlike a simple 2-pin crystal, this is an "active" component. It contains both the quartz crystal and the oscillation circuitry (inverter and capacitors) inside the package. --- ### 3. Pin Configuration (Standard 4-Pin) | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable control or No Connection | | **2** | GND | Circuit Ground | | **3** | Output | Clock Signal Output | | **4** | Vcc | Positive Power Supply | --- ### 4. Applications The MHO315TAD-R is commonly found in: 1. **Networking Equipment:** Routers, switches, and modems requiring precise timing. 2. **Embedded Systems:** Providing the heartbeat for microcontrollers (MCUs). 3. **Industrial Automation:** PLCs and sensor arrays. 4. **Legacy Upgrades:** Often used to replace older through-hole oscillators due to its high reliability.
