The **MHO+56FBD-R** is a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. It is part of the MHO+ series, known for providing high-frequency stability in a compact, reliable package. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature used by MtronPTI. Below are the primary technical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Fixed Frequency Crystal Oscillator (XO) | | **Output Type** | CMOS / TTL Compatible | | **Frequency Range** | Typically 1.000 MHz to 125.000 MHz | | **Package Style** | 5x7 mm Surface Mount (SMD) - 4 Pads | | **Supply Voltage (Vcc)** | 5.0 Volts (±10%) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | RoHS Compliant (Lead-Free) | --- ### 2. Breakdown of the Part Number To understand the specific features, we can decode the alphanumeric string: * **MHO:** Series designation (MtronPTI High-Frequency Oscillator). * **+:** Indicates RoHS compliance. * **5:** Designates the supply voltage (5.0V). * **6:** Designates the stability/temperature range (typically ±50ppm or ±100ppm over -40°C to +85°C, depending on the specific datasheet revision). * **F:** Frequency stability/Duty cycle code. * **BD:** Package/Pinout configuration (5x7mm SMD). * **R:** Packaging suffix (usually indicates Tape & Reel). --- ### 3. Pin Configuration (Internal Architecture) As a 4-pad SMD device, the internal electronic connections are standard for the 5x7mm footprint: | Pin Number | Function | Description | | :---: | :--- | :--- | | **1** | E/D or NC | Enable/Disable (Tri-state) or No Connection | | **2** | GND | Circuit and Package Ground | | **3** | Output | The generated clock signal (Square Wave) | | **4** | Vcc | Supply Voltage (+5.0V) | --- ### 4. Typical Applications This electronic part is commonly used as a "heartbeat" for digital systems that require a 5V logic level: 1. **Industrial Controls:** Embedded systems requiring wide temperature tolerances. 2. **Legacy Systems:** Hardware requiring 5V CMOS/TTL logic levels (where modern 1.8V or 3.3V oscillators are incompatible). 3. **Communication Gear:** Modems, routers, and networking switches. 4. **Data Storage:** Fiber channel and disk drive controllers. --- ### 5. Features and Benefits * **Tri-state Functionality:** Pin 1 allows the output to be high-impedance, which is useful for testing or power-saving modes. * **Hermetically Sealed:** The quartz crystal is sealed in a ceramic package with a metal lid to prevent environmental aging. * **Low Jitter:** Designed for low phase noise to ensure timing accuracy in high-speed data transmission.
