The **MHO324FCD-R** is an electronic component typically categorized as a **Surface Mount Device (SMD) Quartz Crystal Oscillator**. It is widely used in telecommunications and data processing equipment to provide a stable frequency reference. --- ### ## Technical Specifications Below are the primary technical parameters associated with this specific part number: | Parameter | Typical Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (SPXO) | | **Frequency Range** | Typically fixed (often in the MHz range) | | **Package Type** | DIL-14 or SMD equivalent (Metal Can) | | **Input Voltage** | +3.3V or +5.0V DC | | **Output Logic** | CMOS / TTL | | **Frequency Stability** | ±25ppm to ±100ppm | | **Operating Temp** | -10°C to +70°C (Standard) | --- ### ## Key Electronic Features 1. **Oscillator Circuitry:** Unlike a simple passive crystal, the MHO series includes internal active circuitry. It integrates a quartz crystal blank and an oscillation circuit (IC) inside a hermetically sealed metal package. 2. **Output Waveform:** It provides a square wave output, making it compatible with direct clock inputs for Microcontrollers (MCUs), FPGAs, and Digital Signal Processors (DSPs). 3. **Low Phase Jitter:** The "FCD" designation often refers to specific tuning or stability characteristics that ensure low timing noise, which is critical for high-speed data transmission. 4. **Pin Configuration:** Most oscillators in this series follow the standard 4-pin layout: * **Pin 1:** NC (No Connection) or Standby/Enable. * **Pin 2:** Ground (GND). * **Pin 3:** Output. * **Pin 4:** Supply Voltage (Vcc). --- ### ## Common Applications * **Networking Gear:** Used in routers and switches to sync data packets. * **Computing:** Serving as the system clock for motherboards or peripheral controllers. * **Industrial:** Timing for automation controllers where environmental stability is required. --- ### ## Part Number Breakdown (Prefix Interpretation) * **MHO:** Series identifier (Metal Hermetic Oscillator). * **3:** Generally indicates the voltage (e.g., 3.3V). * **24:** Often represents the frequency or a specific package size code. * **FCD:** Tolerance and stability rating code. * **-R:** RoHS Compliant (Lead-free).
