The part number **MHO+67FCD-R** refers to a high-performance **Crystal Oscillator** (often categorized under "Frequency Control" components). Based on standard electronic component nomenclature, this part typically belongs to high-frequency, low-jitter clocking sources used in networking and telecommunications. Below is a detailed breakdown of the electronic characteristics of this component. --- ## 1. Technical Specifications Table | Feature | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (SPXO - Simple Packaged Crystal Oscillator) | | **Output Type** | LVDS (Low-Voltage Differential Signaling) | | **Supply Voltage** | Typically 2.5V or 3.3V DC | | **Frequency Stability** | ±25ppm to ±50ppm (standard range) | | **Package Size** | Usually 7.0 x 5.0 mm or 5.0 x 3.2 mm SMD | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by the **-R** suffix) | --- ## 2. Part Number Breakdown The alphanumeric code provides specific information about the construction of the oscillator: * **MHO:** Series identifier, typically representing a High-Frequency Differential Output oscillator. * **67:** This often refers to the package size and pin configuration (e.g., 6-pad SMD). * **F:** Usually indicates the frequency stability or temperature range (e.g., ±50ppm). * **CD:** Likely refers to the output logic type. In this series, "CD" often denotes **LVDS** output, which is preferred for high-speed data transmission due to low noise. * **-R:** Indicates **RoHS compliance** (lead-free) and often implies Tape & Reel packaging. --- ## 3. Key Electronic Functions ### A. LVDS Output Logic The "CD" designation points to **Low-Voltage Differential Signaling**. This is crucial for: * **Noise Immunity:** Using two wires with opposite signals allows the receiver to cancel out common-mode electromagnetic interference. * **Low Power:** LVDS consumes less power at high frequencies compared to CMOS or LVPECL. ### B. Precision Timing The component uses a quartz crystal blank to generate a highly stable reference clock. This is essential for synchronizing data packets in high-speed hardware. ### C. Jitter Performance Part numbers in the MHO series are designed for **Low Phase Jitter** (typically <1ps RMS). This ensures that the digital "edges" of the clock signal are sharp and precisely timed, preventing bit errors in high-speed communication. --- ## 4. Common Applications These parts are integrated into complex PCBs where timing is critical: 1. **Fiber Optic Modules:** SFP, SFP+, and QSFP transceivers. 2. **Networking Gear:** Gigabit Ethernet switches and high-end routers. 3. **Storage:** SAS/SATA and Fibre Channel controllers. 4. **FPGA Clocking:** Providing a stable reference clock for Xilinx or Intel Altera FPGAs.
