The **MHO+54FBG-R** is a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. It belongs to the MHO series, which is known for its reliability in industrial and communication applications. --- ### 1. Technical Specifications Below is a breakdown of the core technical parameters for this specific part number: | Parameter | Specification | | :--- | :--- | | **Output Type** | HCMOS / TTL | | **Frequency Range** | Typically 1.000 MHz to 125.000 MHz | | **Supply Voltage (Vcc)** | 5.0 Volts (Standard) | | **Frequency Stability** | ±50 ppm (standard for "54" series) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Package Style** | 14-pin DIP (Full Size) - 4 pins used | | **RoHS Status** | Compliant (indicated by -R suffix) | --- ### 2. Key Features The MHO+54FBG-R is designed with several specific electronic characteristics: * **Output Logic:** It provides a square wave output compatible with both HCMOS and TTL circuits, making it versatile for older legacy systems and modern digital logic. * **Tristate Functionality:** The "F" in the part number usually indicates a **Tri-state (Enable/Disable)** function on Pin 1. This allows the output to be placed in a high-impedance state, which is useful for testing or power saving. * **Through-Hole Mounting:** Unlike modern SMD (Surface Mount) oscillators, this uses a 14-pin DIP footprint, though only four pins are physically present (Pins 1, 7, 8, and 14). * **Hermetically Sealed:** The internal crystal is housed in a metal resistance-weld package to ensure long-term frequency stability and protection against environmental moisture. --- ### 3. Pin Configuration The standard wiring for this 14-pin DIP package is as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-state | Enable/Disable Control | | **7** | Ground | Case Ground | | **8** | Output | HCMOS/TTL Clock Signal | | **14** | Vcc | +5.0V Power Supply | --- ### 4. Applications Due to its 5V operation and rugged DIP packaging, this part is commonly used in: 1. **Industrial Controls:** PLCs and automation hardware requiring 5V logic. 2. **Legacy Computing:** Replacement parts for older motherboards or embedded systems. 3. **Communication Equipment:** Base stations and data processing units. 4. **Test & Measurement:** Internal clock references for laboratory instruments.
