The **MHO+27FAD-R** is a high-performance, differential output Crystal Oscillator (XO). It is primarily designed for high-frequency applications requiring low jitter and high stability, such as networking, telecommunications, and data centers. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of the MHO+ series (specifically the 27FAD-R variant): | Parameter | Specification (Typical) | | :--- | :--- | | **Output Type** | LVDS (Low-Voltage Differential Signaling) | | **Supply Voltage (Vcc)** | +2.5V or +3.3V (Model dependent) | | **Frequency Stability** | ±25ppm to ±50ppm (Standard) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Package Size** | 7.0 x 5.0 mm (SMD Package) | | **Function** | Tri-state (Enable/Disable on Pin 1) | | **Termination** | RoHS Compliant / Lead-Free | --- ### 2. Breakdown of the Model Code The nomenclature for this part usually breaks down as follows: - **MHO+**: Series name for MtronPTI High-Frequency Oscillators. - **27**: Represents the package size and voltage characteristic (usually 7.0x5.0mm). - **F**: Represents the Frequency Stability (e.g., ±25ppm). - **A**: Represents the Operating Temperature Range (e.g., Industrial). - **D**: Represents the Output Type (**LVDS**). - **R**: Indicates compliance with **RoHS** standards. --- ### 3. Functional Pin Configuration The device typically features 6 pads for surface mounting: | Pin # | Function | Description | | :--- | :--- | :--- | | **1** | Tri-state | Logic '1' or Open: Output Enabled; Logic '0': High Impedance | | **2** | No Connect | Often used for internal testing or left floating | | **3** | Ground | Case and Circuit Ground | | **4** | Output | Positive Differential Output | | **5** | Complementary Output | Negative Differential Output | | **6** | Vcc | Supply Voltage | --- ### 4. Application Areas Due to the **LVDS** output, this component is ideal for: - **High-Speed Networking:** Gigabit Ethernet, Fibre Channel, and SONET/SDH. - **FPGA Clocking:** Providing a stable reference clock for high-speed I/O. - **Data Storage:** SAN (Storage Area Networks) and high-speed bus interfaces. ---
