The **MHO+56TCD-R** is a high-precision, high-frequency **Crystal Oscillator (XO)**. These components are critical for providing a stable clock signal in high-speed networking and telecommunications hardware. --- ### 1. General Specifications This part belongs to a class of surface-mount oscillators designed for low-jitter performance. | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | CMOS / TTL Compatible | | **Package Type** | SMD (Surface Mount Device) - often 5x7mm | | **Operating Voltage** | Typically 3.3V or 5.0V (Variant dependent) | | **Frequency Stability** | Usually ±25ppm to ±100ppm | | **RoHS Status** | Compliant (indicated by -R suffix) | --- ### 2. Breakdown of the Part Number While specific manufacturer codes can vary slightly, the nomenclature generally breaks down as follows: * **MHO:** Series identifier (often associated with MtronPTI or similar high-reliability manufacturers). * **56:** Physical package size or specific internal circuit architecture (typically 5x7mm footprint). * **T:** Temperature range (often indicates Industrial Grade: -40°C to +85°C). * **C:** Output type (C usually denotes CMOS). * **D:** Duty Cycle / Voltage requirements. * **-R:** RoHS Compliant (Lead-free). --- ### 3. Key Electronic Features #### High Stability The "MHO" series is engineered to maintain a very consistent frequency even when exposed to temperature fluctuations or power supply noise. This is vital for maintaining data integrity in high-speed serial links. #### Low Phase Jitter Phase jitter refers to small timing deviations in the clock signal. In the MHO+56TCD-R, jitter is minimized to ensure that digital circuits (like FPGAs or CPUs) sample data at the exact correct moment. #### Tri-state Function Most oscillators in this series include an **Enable/Disable** (Tri-state) pin. * When the pin is **High**: The oscillator outputs the clock signal. * When the pin is **Low**: The output goes to a high-impedance state, reducing power consumption. --- ### 4. Common Applications * **Networking:** Routers, Switches, and Fiber Optic modules. * **Industrial:** High-speed data acquisition systems. * **Computing:** Server motherboards and storage area networks (SAN). ---
