The **MHO+54FCG-R** is a specific part number belonging to the **MHO+ series** of high-performance crystal oscillators manufactured by **MtronPTI**. These components are frequently used in telecommunications, data processing, and military/aerospace applications where high-frequency stability and reliability are required. --- ### 1. Technical Specifications Table The part number follows a specific nomenclature that defines its electrical and physical characteristics. | Parameter | Specification (Typical for MHO+ Series) | | :--- | :--- | | **Component Type** | Fixed Frequency Crystal Oscillator (XO) | | **Output Type** | CMOS / TTL Compatible | | **Package Style** | 14-pin DIP (Full Size) - 4 pins active | | **Supply Voltage (Vcc)** | +5.0 VDC (indicated by the '5' in the code) | | **Operating Temperature** | Commercial or Industrial grades available | | **Frequency Stability** | ±25ppm to ±100ppm (depending on suffix) | | **Termination** | RoHS Compliant (indicated by the '-R') | --- ### 2. Part Number Breakdown The nomenclature for this series can be decoded as follows: * **MHO+**: The series prefix (High-speed CMOS/TTL 5x7mm or 14-pin DIP standard). * **5**: Represents the Operating Voltage (5.0 Volts). * **4**: Represents the Frequency Stability (typically ±50ppm, though this varies by manufacturer chart). * **F**: Represents the Duty Cycle (typically 40/60% or 45/55%). * **C**: Represents the Temperature Range (usually Commercial: 0°C to +70°C). * **G**: Represents the specific "Full Size" 14-pin DIP package configuration. * **-R**: Indicates **RoHS Compliance** (Lead-free). --- ### 3. Key Electronic Features #### A. Output Logic The device provides a square wave output. Because it is **CMOS/TTL compatible**, it can drive high-speed digital logic gates directly without needing additional buffering, provided the load capacitance is within limits (usually 15pF to 50pF). #### B. Thru-Hole Design The **14-pin DIP** footprint (though it only uses 4 pins: Vcc, Ground, Output, and an optional Tri-state/NC) is designed for through-hole mounting. This makes it ideal for: * Robust industrial environments. * Prototyping on breadboards or perf-boards. * Legacy system repairs. #### C. Tri-state Functionality Most parts in this series include an **Enable/Disable** function on Pin 1. When the pin is pulled low, the output goes into a high-impedance state, allowing for power saving or bus sharing. --- ### 4. Common Applications * **Networking:** Clock generation for Ethernet controllers. * **Embedded Systems:** Master clock for Microprocessors and FPGAs. * **Industrial Control:** Timing for PLCs and automation hardware. * **Testing Equipment:** Signal generators and frequency counters.
