The part number **MHO+62FBD-R** typically refers to a high-precision, surface-mount (SMD) clock oscillator. These components are essential in digital electronics for providing a stable timing signal (clock pulse) to microprocessors, FPGAs, and communication interfaces. --- ### 1. General Specifications The "MHO" series is generally produced by manufacturers like **MtronPTI**, known for high-reliability frequency control products. | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | SMD (Surface Mount Device) | | **Size** | 5.0 x 7.0 mm (standard for 4-pad or 6-pad layouts) | | **Frequency Stability** | Usually ±25ppm to ±100ppm | | **Output Type** | HCMOS/TTL Compatible | | **RoHS Status** | Compliant (indicated by the "R" suffix) | --- ### 2. Part Number Breakdown (Interpretation) While specific coding can vary by manufacturer year, the alphanumeric string generally breaks down as follows: * **MHO:** Series designation (High-speed CMOS/TTL Oscillator). * **+:** Often indicates an upgraded version or Lead-Free/RoHS compliance. * **62:** Usually refers to the operating voltage (e.g., 6 indicates 3.3V or 5V operation, though this varies by data sheet). * **F:** Frequency Stability code (commonly ±100ppm or ±50ppm depending on the specific catalog). * **BD:** Temperature Range and Duty Cycle code (typically -40°C to +85°C for industrial use). * **R:** Packaging (Tape and Reel) or RoHS Compliance. --- ### 3. Key Electronic Characteristics These parts are designed to be "plug-and-play" timing sources. Unlike a simple crystal, an oscillator includes the internal circuitry required to vibrate the quartz. 1. **Supply Voltage ($V_{DD}$):** Usually operates at **3.3V** or **5.0V**. 2. **Tri-State Function:** Pin 1 is often a "High Impedance" or "Enable/Disable" pin. When pulled low, the output stops, allowing for power saving. 3. **Low Jitter:** Designed for high-speed data transmission where timing precision is critical to avoid data errors. 4. **Load Capacitance:** Optimized for a 15pF to 30pF load. --- ### 4. Typical Pinout (4-Pad Configuration) If you are looking at the bottom of the component, the pinout is generally standard for the 5x7mm footprint: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable (Tri-state) or No Connect | | **2** | GND | Circuit Ground | | **3** | Output | Clock Signal (Square Wave) | | **4** | $V_{DD}$ | Supply Voltage | --- ### 5. Common Applications * **Networking:** Ethernet switches and routers. * **Industrial:** PLCs and embedded controllers. * **Computing:** High-speed I/O interfaces. * **Storage:** Fiber Channel and SAN equipment.
